Jacoco-related failure in multiproject build

I have a multi-project Gradle v1.8 build that applies the jacoco plugin to one of the subprojects:

apply plugin: 'jacoco'

When I build from the top-level directory of the parent project, I see a lot of stack traces indicating something failing:

:common:page-object-core:test

But when I go into the subproject directory and build there, I see no such error.

Can anyone comment?

Thanks.

Here is a test project that reproduces the failure:

From the top level directory, this fails:

But from proj1/, to which jacoco plugin has been applied, this does not fail:

Looks like you have stumbled upon GRADLE-2859, which is caused by GRADLE-2860. I had the same problem with my integ tests. The following fixed it for me:

task integTest(type: Test) {
        ...
        // GRADLE-2859
        systemProperties['user.dir'] = workingDir
    }

Thanks. I’m just getting back to this.

Your solution works for me, too.

But is there a way to arrange for this assigment to take place for all tasks of type Test in a multiproject build?

I tried

allprojects {
    tasks.withType(Test) {
        systemProperties['user.dir'] = workingDir
    }
}

but found that the jacoco failure still obtains. I have a 25-submodule build. I’d like to centralize this in one place, rather than maintain it for all test/intTest tasks explicity.

Thanks much.

I find that this works to flow the config down to subprojects:

apply from: file("${rootDir}/gradle/jacoco.gradle")

where this apply-from-file is used in place of

apply plugin: 'jacoco'

and contains

apply plugin: 'jacoco'
  test {
    systemProperties['user.dir'] = workingDir
}
