Getting "ClassNotFoundException: org.jacoco.agent.rt.internal_9dd1198.PreMain" with 1.7's Jacoco plugin

I’m attempting to replace Cobertura with Jacoco in our build. I’ve removed all the Cobertura references and I’ve added the following in their place: root.build.gradle

...
    subprojects {
        ...
        apply plugin: 'jacoco'
        jacoco { toolVersion = '0.6.3.201306030806' }
        ...
    }
    ...
    jacocoTestReport {
        // TODO: Temporary work-around -- http://issues.gradle.org/browse/GRADLE-2764
        additionalSourceDirs = files(sourceSets.main.allJava.srcDirs)
          reports {
            html.enabled false
            xml.enabled true
        }
    }
    ...

This works fine when I was testing it with

./gradlew test jacocoTestReport

However, when I switched to

./gradlew build jacocoTestReport

and my integration tests came into place, I started getting the following failure:

Has anyone seen anything like this or have any suggestions?

I finally came back to this and figured it out. Turns out it’s another manifestation of a known issue – GRADLE-2859. Specifying

systemProperties['user.dir'] = workingDir

fixed the issue.
