 Description   

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')
    }
}

    compile fileTree(dir: 'lib/runtime', include: '**/*.jar')
    testCompile fileTree(dir: 'lib', include: '**/*.jar')

    testClassesDir = sourceSets.integrationTest.output.classesDir
    classpath = sourceSets.integrationTest.runtimeClasspath

Do you have the full stack for the failure?

Comment by tntim96 [ 28/Mar/13 ]

I've attached the standard and error output. The process hangs and has to be manually ended.

Comment by Adam Murdoch [ 02/Apr/13 ]

Looks like the test is throwing an exception that cannot be deserialized in the build process. Gradle should deal with this, so it looks like there's something broken in there. Can you get more details from the logging to see what kind of exception is being thrown by the tests?

Comment by tntim96 [ 02/Apr/13 ]

I'll try, however, this is easy to replicate:

  1. Checkout https://github.com/tntim96/JSCover.git
  2. Download HTML Unit 2.12 and extract to the same parent directory as JSCover
  3. Copy in build.gradle code from above
  4. Run `gradle acceptanceTest`
Comment by tntim96 [ 02/Apr/13 ]

OK, I've attached out.txt when running with debug.

The output has an error, 'Caused by: java.net.BindException: Address already in use: JVM_Bind'. Does Gradle automatically try to run test concurrently? http://www.gradle.org/docs/current/userguide/java_plugin.html states that maxParallelForks defaults to 1.

OK. My issue is solved by adding `forkEvery = 1` for the acceptance tests, but you may want to keep this open to have gradle handle the BindException deserialisation.
