Use IntelliJ to debug a Gradle Execute Task

Question

I have the following Gradle task:

task execute(type:JavaExec, dependsOn:['build']) {
    main = 'com.something.Main'
    classpath = sourceSets.main.runtimeClasspath
}

When I debug the task in IntelliJ I get the following error:

ERROR: transport error 202: connect failed: Connection refused
FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [debugInit.c:750]
:execute FAILED

Answer 1

It seems later versions of IntelliJ Idea cannot connect debuggers to forked test runners when using the Gradle Test runner.

In your sources root, add a gradle.properties file with the next two lines:

maxTestForks = 1
testForkEvery = 0

That should do the job.
