we have use sonar/jacoco for our code coverage, and one it stopped working, and the error message is:
Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.2:sonar (default-cli) on project prism-parent-pom: Execution default-cli of goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.2:sonar failed: Unable to load the mojo 'sonar' in the plugin 'org.sonarsource.scanner.maven:sonar-maven-plugin:3.2' due to an API incompatibility: org.codehaus.plexus.component.repository.exception.ComponentLookupException: org/sonarsource/scanner/maven/SonarQubeMojo : Unsupported major.minor version 52.0
After some painful comparison of before and after logs, I found out the sonar-maven-plugin change from version 3.0.2 to 3.2, even though there is no change to the pom file.
I also run 'mvn dependency:tree' and don't see any dependency of sonar.
Last i updated the pom to specify the sonar-maven-plugin version to enforce it to use the version that used to work, but it still doesn't help, here is my parent pom
