SDN-R compile frontend-maven-plugin

SDN-R ODLUX does require compilation of Javascript and Typescript files as runnable code for the Web-Clients. 

A specific compilation environment is created, that requires an extension of the actual version of "frontend-maven-plugin".

Dependency is like this:

<plugins>
    <plugin>
        <groupId>com.github.eirslett</groupId>
        <artifactId>frontend-maven-plugin</artifactId>
        <!-- Use the latest released version:
        https://repo1.maven.org/maven2/com/github/eirslett/frontend-maven-plugin/ -->
        <version>LATEST_VERSION</version>
        ...
    </plugin>
...

The extension for ONAP SDN-R is published in github repository https://github.com/jacksitlab/frontend-maven-plugin.

Usage in ODLUX pom files

In ONAP ODLUX the plugin is used as already pre-compiled plugin.

For getting it from public available repository, the follwong additonal repository was added to the related ODLUX pom files:

<pluginRepository> 
  <id>highstreet repo</id> 
  <url>https://cloud-highstreet-technologies.com/mvn/</url>
  <snapshots> 
     <enabled>true</enabled> 
     <updatePolicy>always</updatePolicy> 
  </snapshots> 
</pluginRepository>
