I am referring to the official document
[sonar-java/CUSTOM_RULES_101.md at master · SonarSource/sonar-java · GitHub]
to try to develop a plug-in for Java custom rules MD self defining Java rules.I change the name of "pom_SQ_8_9_LTS.xml"to “pom.xml” and use the instruction “mvn clean install” to always prompt errors.The error content is:
"[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project java-checks-test-sources: Fatal error compiling: error: release version is not supported 16 → [Help 1]”.
My local environment is jdk11. SonarQube version is 8.9.3LTS，Maven has two versions, 3.6.3 and 3.8.3, none of which can be built successfully. Also，the information set in pom.xml is
<sonarqube.version>8.9.0.43852</sonarqube.version>
<sonarjava.version>6.15.1.26025</sonarjava.version>
Can you guys give me some advice？
thank you so！
Hello @KevinJin
It seems to me that you are trying to build the whole Java analyzer project, which requires Java 16 to build.
java-custom-rules-example is a separated nested sample project, you should therefore run the command from this folder, not the root of the analyzer.
Hope it helps,
Quentin
