Maven Projects

If you have imported an existing maven project into eclipse - you may run into eclipse-only build issues (both runtime when deploying the war to a local tomcat and at design time resolving spring jars) because the maven dependencies libarary is missing from project | Java Build Path | Maven Dependencies

Specific to WAR projects - insert the following in your .classpath file off the project

	<classpathentry exported="true" kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
		<attributes>
			<attribute name="maven.pomderived" value="true"/>
			<attribute name="org.eclipse.jst.component.nondependency" value=""/>

Install git-review

<<TODO: describe a Linux client set-up for Git and git-review>>

To install git-review on Linux (Ubuntu), type the following command.

sudo apt-get install git-review

Windows Setup

Note: The DCAE and SDC  repo will not fully clone in a windows environment (even git-bash) until some file paths are reduced below 255 chars -  DCAE-24 - Getting issue details... STATUS  and  SDC-21 - Getting issue details... STATUS  - you may use Linux or OSX native or VMs as an alternative for now.

Enabling long paths in windows - thanks Michael Lando

Windows Subsystem for Linux

Just install the Windows Subsystem for Linux https://docs.microsoft.com/en-us/windows/wsl/install-win10  and the Ubuntu 16 tools https://www.microsoft.com/en-ca/p/ubuntu/9nblggh4msv6?rtc=1&activetab=pivot:overviewtab and skip git-bash, putty and cygwin.

Installing Git

To install Git on your client, visit: https://www.atlassian.com/git/tutorials/install-git, and download the appropriate installation image for your host. Once downloaded, execute the installation script ("open" the .msi file).

During installation, you will see the following dialog box.  Include the "Git Bash" and "Git GUI" components (this is the default).To do this, leave the following boxes checked:

If you intend to type Git commands from the Windows Command Prompt, leave the default setting for adjusting the PATH environment:

The repositories use Unix-style line-feed for line termination, so on your windows Git client, select the conversion option:

Select the following option based on your own preference (non-default shown, so 'winpty' is not required):

Choose the defaults here:

The installer lets you choose the experimental 'difftool'; either choice will work. Continue with the installation dialogs until the installation is complete.

Install Python on Windows (optional) - required to get pip for git-review

Not all components require Python for development. See the documentation for your component in the Development Guides section. (Note: the "node-gyp" tool requires Python.)

Download Python version 2.7.10:

1. • 32-bit: https://www.python.org/ftp/python/2.7.10/python-2.7.10.msi
   • 64-bit: https://www.python.org/ftp/python/2.7.10/python-2.7.10.amd64.msi

Execute the install file that you just downloaded. (You must have administrative privileges.) During installation, select "Add python.exe to Path", overriding the default setting. Also, be sure to install "pip" (this is the default).

Continue with the installation until it is completed.

Set up Git review and Configure Git

Run Git Bash as Administrator (for example, in Windows 10, use the Windows menu, scroll to the Git directory, right-click on Git-bash, and select "Run as administrator":

Within Git Bash, type the following command: assumes you already installed python above

$ pip install git-review

To use git review, you have to be in a Git clone directory that already contains a (possibly hidden) .gitreview configuration file (see Gerrit/Advanced usage#Setting up a repository for git-remote), otherwise you will get the error message UnboundLocalError: local variable 'no_git_dir' referenced before assignment.

Configure Git to remember your Linux Foundation user name and email address (the user name and email address associated with your Linux Foundation login):

git config --global user.email <your_LF_account_email>

git config --global --add gitreview.username <your_LF_user_name>

Configure git review

git config --global gitreview.remote origin

If you are using VPN, you might encounter a proxy problem while connecting to the Linux Foundation website. To avoid the problem, you should add the proxy setting in git config, using the following command:

git config --global https.proxy https://<proxy username>:<proxy password>@<proxy url> 

git config --global http.proxy http://<proxy username>:<proxy password>@<proxy url>

NOTE: When entering the proxy username, you might be required to add the domain name in front of the username.

Install Putty and Generate Keys

PuTTY is a terminal emulator that uses Secure SHell (SSH) to communicate with a host. You need to install PuTTY in order to create a public/private encryption key pair. This pair of keys enables Git to communicate securely with the repositories.

To install PuTTY, visit, www.putty.org and follow the links to the appropriate Windows installation for your machine (32-bit or 64 bit). The downloaded file will be named putty-0.67-installer.msi or the like.

Execute the .msi file. Use all the default settings, thereby ensuring that you will install pageant.exe, plink.exe, and puttygen.exe.

Generate Public and Private Keys

OSX

Windows

The puttygen utility, installed with putty, generates public and private keys used for secure communication with Gerrit.

To do this, right-click on C:\Program Files (x86)\PuTTY\puttygen.exe and select Run as Administrator:

Answer "Yes" to the User Account Control challenge. Then click the "Generate" button in the puttygen window. puttygen will ask you to move your mouse over its dialog box to generate random seed bits. After it has computed a public key, it will display a dialog box resembling the following:

If you want to edit this key pair in the future, create a text file containing a short phrase, called a "passphrase". Copy and paste this passphrase into the "Key passphrase" and "Confirm passphrase" lines, then select "Save public key" and choose a filename (e.g. public.txt); also "Save private key" and choose another filename (e.g. private.ppk). Since you ran puttygen as Administrator, the files are visible to Windows Explorer.

Close puttygen.

Load Your Private Key Into Pageant

Pageant is an SSH authentication agent. It holds your private keys in memory, already decoded, so that you can use them often without needing to type a passphrase.

To load your private key into pageant, right-click on the private key file (e.g. private.ppk in this example), and select Load into pageant:

This action not only loads private.ppk into pageant, but also starts pageant if it is not already running. You will be prompted for the passphrase that you entered into puttygen when you created the key. If successful, pageant will load the key without further interaction.

Set the GIT_SSH Environment Variable

From the Desktop, right-click the Windows logo at the very bottom left corner of the screen,  , and select "System". Within the System dialog box, select "Advanced system settings" to get the Power User Task Menu.

In the next dialog box, select "Environment Variables":

If you don't already have a GIT_SSH entry in your System Variables list, click "New..." and create GIT_SSH, defined to be the location of plink.exe :

Copy/paste the known_hosts entries listed, into a file named known_hosts under your .ssh profile (something like C:\Users\<my-id>\.ssh) (if known_hosts does not exist, create it).

Install NodeJS

The dcae build will install npm in most cases - however if you run into issues like the following - install it yourself

Install NodeJs from https://nodejs.org/en/

verify your install by doing 

$ npm -version
3.10.10

From git bash

• npm install bower -g
• npm install grunt-cli -g
  
  

IDEs

IDE: Eclipse: Does Not Support Gerrit Plugin

Eclipse plugins (including the Mylin Gerrit connector plugin and Egit) do not support a 2.12 Gerrit server, so if you use Eclipse as your development IDE, you must do reviews using the Gerrit web interface.

Setting up the ONAP Checkstyle in Eclipse

(There may well be an easier way but this works)

The first issue is that the current ONAP master tagged version of the checkstyle does not work with Eclipse Oxygen/Photon (and maybe other versions) because of the "curly bracket" issue. There is a fix on the way but it's not here yet. The current tagged version of oparent we are using in Policy is 1.2.1.

Hack oparent to fix "curly bracket" issue

To get around this issue, check out oparent, checked out the 1.2.1 tag, fixed the "curly bracket" bug and built it on my local machine.

1. Check out oparent
2. git tag -l
3. git co tags/1.2.3 -b 1.2.3
4. If you want CheckStyle to ignore generated files, do the following:
   1. Add the following tag to the above file:
      <module name="SuppressionFilter">
        <property name="file" value="<absolute path to the directory of the file>/suppressions.xml"/>
      </module>
   2. Create a file called "suppressions.xml" in the folder given above, and put the following content in it:
      <?xml version="1.0"?>
      <!DOCTYPE suppressions PUBLIC
        "-//Checkstyle//DTD SuppressionFilter Configuration 1.2//EN"
        "https://checkstyle.org/dtds/suppressions_1_2.dtd">
      <suppressions>
        <suppress files="[\\/]generated-sources[\\/]" checks="[a-zA-Z0-9]*"/>
      </suppressions>
5. The versions in the POMs in oparent are snapshot, so we need to change those to 1.2.1
    mvn versions:set -DnewVersion=1.2.1
6. Now build locally:
   mvn clean install

Set "ONAP" configuration in Eclipse

To set the newly built checkstyle files in Eclipse:

1. Preferences->Checkstyle
2. Click "New"
3. Select "External Configuration File"
4. Give it a name eg ONAP
5. Point at the file <your_git_folder>/oparent/checkstyle/src/main/resources/onap-checkstyle/onap-java-style.xml  
   (assuming you have downloaded the oparent repo)
6. Click OK
7. Select "ONAP" configuration and click "Set as Default"
8. Select "Apply and Close"

Apply "ONAP" configuration to a project in Eclipse

Now we need to activate the checkstyle on one project and set it as the blueprint for all of them:
Select a project in eclipse and right click->Properties->Checkstyle
check "Checkstyle active for this project"
Select the "ONAP" checkstyle profile
Click "Apply and Close"

Spread blueprint to other projects in Eclipse

Now spread the profile to all other projects:

1. Select all the projects you want to apply the profile to in the Eclipse project explorer (not the one that you set up above)
2. Right click->Checkstyle->Configure projects from blueprint
3. Select the project you set up above
4. Now all the projects have the correct checkstyle setup.

Sorry this was so long, how can something so simple be so complex!

IDE: IntelliJ

Installing Intellij Community Edition on Linux 

Download

https://www.jetbrains.com/idea/download/#section=linux

Unpack the ideaIC.gz or ideaIU.gz file.

A new instance must not be extracted over an existing one. The target folder must be empty.

tar xfz ideaIC.tar.gz or ideaIU.tar.gz. <new_archive_folder>

The recommended install location according to the filesystem hierarchy standard (FHS) is /opt. For example, it's possible to enter the following command:

sudo tar xf -*.tar.gz -C /opt/

Go to the bin directory, for example

cd opt/-*/binH

Start Intellij

Run idea.sh from the bin subdirectory.

Refer to https://www.jetbrains.com/help/idea/installing-and-launching.html

Installing IntelliJ Community Edition and the Java SDK on Windows

If you are using IntelliJ to do Java compilations, download the IntelliJ installation image from https://www.jetbrains.com/idea/. The installation dialog gives you the opportunity to associated IntelliJ with file type .java, among others. Installation takes several minutes.

Other Tools

The component you are working on may require additional tool installations, see the relevant section under Development Guides.

Maven

For console (mvn) Install maven 3.3.3+ (currently 3.5.0) - as 3.2.x will have issues with the ODL certificate not matching

Will also fix

Selecting a connection method

Once Git is installed, you will need to select a connection method to the Gerrit host, https://gerrit.onap.org/.

We recommend using SSH, in which case you need to register your private key in your account settings on the Gerrit host. However, if you are using a Virtual Private Network (VPN), you will require the HTTPS method, since most VPNs won't allow an ssh connection.

SSH Connection (Recommended)

Log in to the Gerrit host https://gerrit.onap.org/, pull down the menu under your user name (at the extreme top right of the browser window), click on "Settings":

Click your account name on the top right corner of the website and click on Settings.

In the Settings window, select SSH Public Keys, and then click Add Key... .

 Enter the public PuTTY key you generated above (by copying and pasting the entire contents of the file public.txt, in our example above.) and click Add.

HTTPS Connection (Alternate)

If you choose to use HTTP/HTTPS, you'll need to generate an access password. Log in to the Gerrit host https://gerrit.onap.org/, pull down the menu under your user name (at the extreme top right of the browser window), click on "Settings", and select "HTTP Password":

The icon at the right of the generated password allows you to copy the generated password to your clipboard, it will be needed when you interact with Git/Gerrit.

This password may have a limited time to live, so you might get errors like this one:

Problem running 'git remote update gerrit'
Fetching gerrit
fatal: unable to access 'https://USERNAME@gerrit.onap.org/r/a/mso/ ': Unknown SSL protocol error in connection to gerrit.onap.org:443 error: Could not fetch gerrit 

Regenerating a password will most likely solve the connectivity issue. Sometimes, the Gerrit interface on HTTPS might be temporarily faulty, so retries might be needed.

Working with a Proxy

For developers working with a proxy, you might have proxy issues connecting to Linux Foundation website. To avoid the connection issue, you must define the proxy setting for both IntelliJ and Git.

To configure the proxy settings in IntelliJ, click File -> Settings -> Appearance & Behavior -> System Settings -> HTTP Proxy, enter the correct proxy settings and click Apply. In case of Manual proxy configuration, while entering the Host name, there is no need to write http:// in front of the URL. For example, if the proxy value is http://one.proxy.com, you would put one.proxy.com as the Host name.

To configure the proxy settings for Git, play the following command:

git config --global https.proxy https://<proxy username>:<proxy password>@<proxy url> 

git config --global http.proxy http://<proxy username>:<proxy password>@<proxy url>

Note: while entering the proxy username, sometimes it may require to add the domain name in front.

Building all ONAP projects

see Building Entire ONAP

Maven Example settings.xml

The most current settings.xml that you should use to build ONAP can be found in the oparent repo at https://git.onap.org/oparent/plain/settings.xml

Save this Maven settings.xml as your ~/.m2/settings.xml 

WSL users can point to one common repo across Windows and Ubuntu as :

ln -s /mnt/c/Users/<username>/.m2 ~

Some notes on the settings.xml:

• The use of the staging repo has been eliminated with the rollout of https://wiki.onap.org/display/DW/Independent+Versioning+and+Release+Process in Sept. 2017.

If you are behind a proxy you can add a proxy section to your settings.xml 

	<proxies>
        <proxy>
            <id>evil-corp-http</id>
            <active>true</active>
            <protocol>http</protocol>
            <host>proxy.evil-corp.com</host>
            <port>599</port>
            <nonProxyHosts>localhost|127.0.0.1|*.evil-corp.com|*.happy.evil-corp.com|fun.evil-corp.com</nonProxyHosts>
        </proxy>
        <proxy>
            <id>evil-corp-https</id>
            <active>true</active>
            <protocol>https</protocol>
            <host>proxy.evil-corp.com</host>
            <port>599</port>
            <nonProxyHosts>localhost|127.0.0.1|*.evil-corp.com|*.happy.evil-corp.com|fun.evil-corp.com</nonProxyHosts>
        </proxy>
	</proxies>

Local SonarQube Setup

It can be useful to have SonarQube running locally rather than pushing through CI for feedback.

This can be done using docker:

Images of the Community, Developer, and Enterprise Editions are available on Docker Hub.

1. Start the server by running:

   $ docker run -d --name sonarqube -p 9000:9000 sonarqube:latest

2. Log in to http://localhost:9000 with System Administrator credentials (login=admin, password=admin).
3. Click the Create new project button to analyze your first project.
