Sonar Gradle plugin 3.1 does not resolve Java Toolchain path correctly

[grimsa (Gediminas Rimša)]

Versions:

• Gradle 6.7.1 (same result with 6.8)
• Sonar Gradle plugin 3.1
• SonarCloud

Gradle configuration:

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(14)
    }
}

Running Sonar analysis on CI server results in:

Invalid value for 'sonar.java.jdkHome' property, defaulting to runtime JDK.	
Configured location does not exists: '/opt/bitnami/apps/jenkins/jenkins_home/workspace/ol-sandbox-test-pipeline_develop/Optional[/usr/lib/jvm/jdk-14.0.2+12]'

Configured location does not exists: '/opt/bitnami/apps/jenkins/jenkins_home/workspace/ol-sandbox-test-pipeline_develop/Optional[/usr/lib/jvm/jdk-14.0.2+12]'	

Running on my machine results in similar output (log with --info):

It seems that JDK path should be used as-is, instead of being appended to some path prefix.

Maybe the cause is incomplete implementation of https://jira.sonarsource.com/browse/SONARGRADL-73 ?

Hi,

I was able to reproduce, there is indeed a mistake in the implementation of SONARGRADL-73.

Here is a ticket you can follow:

[SONARGRADL-76] Invalid value for 'sonar.java.jdkHome' - SonarSource

Thanks for the feedback!

I have just release version 3.1.1 of the SonarScanner for Gradle to fix this issue.

I can confirm that we no longer see those messages in the logs after upgrading to 3.1.1.

Thanks!
