Could not resolve all files for configuration ':condor:compileClasspath'

[knitin (Nitin K)]

Objective: We are trying to switch to using Java 11 from Java 8. But the Jenkins pipeline fails to build.

sonarqube ver 3.0
Steps:
Run the gradlew build before running the gradlew sonarqube

This is the command we are running:

CI=true ./gradlew sonarqube -Dsonar.login=${SONAR_LOGIN} -Dsonar.host.url=${SONAR_URL} -x test -x compileJava -x compileTestJava -x compileScala -x compileTestScala -x compileKotlin -x compileTestKotlin -Dsonar.pullrequest.key=xx -Dsonar.pullrequest.branch=pr-new -Dsonar.pullrequest.base=master -Dsonar.pullrequest.provider=GitHub

When running this command, we see the error in the log:

==============================
* What went wrong:

Execution failed for task ':sonarqube'.
> Could not resolve all files for configuration ':condor:compileClasspath'.
   > Could not resolve project :segment_db.
     Required by:
         project :condor
      > Unable to find a matching variant of project :test_db:
          - Variant 'apiElements' capability com.test_db:1.0-SNAPSHOT:
              - Incompatible attribute:
                  - Required org.gradle.jvm.version '8' and found incompatible value '11'.

              - Other attributes:
                  - Found org.gradle.category 'library' but wasn't required.
                  - Required org.gradle.dependency.bundling 'external' and found compatible value 'external'.
                  - Required org.gradle.usage 'java-api' and found compatible value 'java-api-jars'.
                  - Required org.jetbrains.kotlin.platform.type 'jvm' but no value provided.

==============================

Problem: If we are skipping the test, compile etc, shouldn’t it not throw this error:
Could not resolve all files for configuration ‘:condor:compileClasspath’.

The temporary fix is: we added
-Dsonar.scanner.force-deprecated-java-version-grace-period=true this to the above command and the build passes. However, once you deprecate support for Java 8, will this still work?

Please let me know if there is a workaround for this.
Any help will be greatly appreciated.

Hello @knitin ,

The compilation step is required for the analysis. If your build requires Java 8 then we recommend the following process:

gradle build ...
export JAVA_HOME=/path/to/java11
gradle sonarqube ...

This will build your project with Java 8 and run the analysis with Java 11. You can find more information for the migration in our documentation.

Thanks @Martin_Bednorz - We were able to identify the root cause of our issue. We had some references to Source & Target compatibility to java 8 version. That fixed the issue for us. We were already doing the solutions mentioned in the documentation.

Thanks.
