Sonar-runner plugin fails due to casting exception

Help/Discuss

Hi all,

Running into a problem and I’m not sure what to do. I have java project I’m building with Gradle, and I’m using the sonar-runner plugin in my build script. Here is the error that is produced:

:compileJava UP-TO-DATE
:generateBuildVersion UP-TO-DATE
:processResources UP-TO-DATE
:classes UP-TO-DATE
:compileTestJava UP-TO-DATE
:processTestResources UP-TO-DATE
:testClasses UP-TO-DATE
:compileUnitTestJava UP-TO-DATE
:processUnitTestResources UP-TO-DATE
:unitTestClasses UP-TO-DATE
:unitTest UP-TO-DATE
:test UP-TO-DATE
:sonarRunner

FAILURE: Build failed with an exception.

* What went wrong:
org.gradle.api.DefaultTask_Decorated cannot be cast to org.gradle.api.tasks.testing.Test

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
java.lang.ClassCastException: org.gradle.api.DefaultTask_Decorated cannot be cast to org.gradle.api.tasks.testing.Test

BUILD FAILED

My sonar setup in the build script is fairly straightforward, so I’m not sure why this is failing:

apply plugin: 'sonar-runner'

sonarRunner{

sonarProperties{
    property"sonar.host.url","http://fooserver"
    property"sonar.jdbc.url","jdbc:mysql://fooserver/sonar"
    property"sonar.jdbc.driverClassName","com.mysql.jdbc.Driver"
    property"sonar.jdbc.username","foo"
    property"sonar.jdbc.password","bar"
}

}

I’ve used sonar-runner plugin in the past with successful results. Here is the version of the wrapper I’m using (I’ve also tried 2.4 with the same results)

wrapper.gradleVersion = '2.2.1'

Any help would be appreciated.

Can you show the rest of your build script? Are you reconfiguring the default test somehow?

It appears that yes, we are changing the default test, but I might be able to remove this:

task test(
overwrite: true,
dependsOn: [unitTest],
group: 'Verification',
description: 'Run all tests') {}

That’s the problem. You are trying to redefine the test task as DefaultTask. Seems like the Sonar plugin doesn’t like that. A better option to introduce a completely new task with a different name like allTests that declares task dependencies on all of your Test tasks. And of course you could just call the lifecycle task check (which however might execute other static code analysis tasks if you apply relevant plugins).

Fantastic! I took that redefinition of the test task out of my script and it’s working now. Thank you so much!
