[#GRADLE-2720] JSCover - MessageIOException (gradle-1.5-rc-3)

I was looking at converting JSCover's build (https://github.com/tntim96/JSCover/) from Ant to Gradle, but get the following error when running `gradle acceptanceTest`

Unexpected exception thrown.
org.gradle.messaging.remote.internal.MessageIOException: Could not read message from '/127.0.0.1:50099'.

The gradle build is shown below. As well as checking out JSCover, you need to unzip HtmlUnit-2.12 to the same parent directory. Tests run fine in Ant, IntelliJ and Eclipse.

I am new to Gradle, so apologies if it's a silly mistake, but couldn't find anyone with similar issues. I also notice the error still occurs when running a single test.

apply plugin:'java'

sourceCompatibility = 1.5

sourceSets {
    integrationTest {
        java.srcDir file('src/test-integration/java')
        resources.srcDir file('src/test-integration/resources')
    }
    acceptanceTest {
        java.srcDir file('src/test-acceptance/java')
        resources.srcDir file('src/test-acceptance/resources')
    }
}


dependencies {
    compile fileTree(dir: 'lib/runtime', include: '**/*.jar')
    testCompile fileTree(dir: 'lib', include: '**/*.jar')
    integrationTestCompile sourceSets.main.output
    integrationTestCompile configurations.testCompile
    integrationTestCompile sourceSets.test.output
    integrationTestRuntime configurations.testRuntime
    acceptanceTestCompile sourceSets.main.output
    acceptanceTestCompile configurations.testCompile
    acceptanceTestCompile sourceSets.test.output
    acceptanceTestCompile fileTree(dir: '../htmlunit-2.12/lib', include: '**/*.jar')
    acceptanceTestRuntime configurations.testRuntime
}

task integrationTest(type: Test) {
    testClassesDir = sourceSets.integrationTest.output.classesDir
    classpath = sourceSets.integrationTest.runtimeClasspath
}

task acceptanceTest(type: Test) {
    testClassesDir = sourceSets.acceptanceTest.output.classesDir
    classpath = sourceSets.acceptanceTest.runtimeClasspath
}

check.dependsOn integrationTest, acceptanceTest
