Address already in use, when running tests.

[gil]

Hi guys,

For some reason, when I run "gradle test" it's trying to run the JVM with this:

Listening for transport dt_socket at address: 5005

And, after a while, it gives a "Address already in use" error. If I remove the plugin it won't start the JVM in debugging mode.

I've also tried this, with no success:

gretty {
    contextPath = ''
    loggingLevel = 'ERROR'
    inplaceMode = 'hard'
    jvmArgs = [
        '-Xrunjdwp:transport=dt_socket,address=5006,server=y,suspend=n'
    ]
    debugPort = 5006
    debugSuspend = false
    scanInterval = 0
    fastReload = false
}

I don't know why it's affecting the test task, even when I don't use any of gretty's tasks. Is that because of the farms feature? Can someone please help me?

This seems to be a bug. In my case if I run gradle with --info I can see gretty not honoring the debugPort value provided in the build.gradle file. It always takes 5005 and in my case it was in use.
