Timeline of events


To prevent dependency issues, this migration is planned to happen in 2 stages. 

Stage 1 will use hardcoded sonar goals to the needed plugin version to avoid waiting on dependencies from where this can be inherited.

Stage 2 will be a cleanup stage and work towards fixing the plugin in the dependencies like oparent and slowly migrate teams to it while removing hardcoded sonar goals.

STAGE 1

  1. RELENG → Will add the needed changes in ci-management for each project and run a test in the sandbox
  2. RELENG → will post the restults of the sandbox test in the 3rd column below.
    • This is not reflecting if the Sonar report actually pass or failed a quality gate. Instead, this result is the outcome of running the Sandbox job using the changes in ci-management.
  3. TECHTEAM → Review the results and comments posted by Releng in column 4. PTLs will be mentioned explicitly to notify them that the next action is on their team.
  4. TECHTEAM&RELENG → Will work on any additional comments/questions/issues from column 4 and 5.


SONAR COVERAGE DROP TO 0%

Sonar Cloud made an update on the jacoco plugin where they dropped support for .exec file format. We need to use .xml instead. 

Please look for more information in https://community.sonarsource.com/t/sonar-coverage-dropping-to-0-for-some-projects/18521/2

Some teams like APPC have upgraded their reports and coverage was restored for them. Please follow their examples: https://gerrit.onap.org/r/#/c/appc/parent/+/100156/, https://gerrit.onap.org/r/#/c/appc/+/100155/


Also, OPARENT has been updated with the fix too https://gerrit.onap.org/r/#/c/oparent/+/100168/ included in 3.0.0-SNAPSHOT 


STAGE 2

  1. Update oparent to upgrade the sonar plugin and Jacoco configuration to the latest plugin required by SonarCloud: https://sonarcloud.io/documentation/analysis/scan/sonarscanner-for-maven/
  2. Make an oparent release wit this change
  3. Migrate teams to the new oparent while also removing the hardcoded goals in their sonar ci-management changes from the above table

SonarCloud migration notes


Ready to migrate? Things to consider and challenges faced with the currently migrated teams

    • Teams will still be using the same Jenkins jobs
    • SonarCloud is based on SonarQube 8.0 with +- some feature and plugin differences
    • SonarQube will stay around for some time, but eventually will be deprecated (mid next year)
    • Warnings in Quality Gates are no longer applicable in SonarCloud
    • Teams using the "org.sonarsource.scanner.maven" plugin, might face issues during the migration since this plugin calls SonarQube directly in older versions.

Testing the migration

The reports will now be posted under: https://sonarcloud.io/organizations/onap/projects

Jenkins jobs do not change.
