Run Test type tasks parallely GPars

Help/Discuss
1

Hi, I’m trying to run multiple multiple Test type tasks parallely using GPars like:

task parallelTests {

    def tasksToRun = []
    tasksToRun << 'testsA'
    tasksToRun << 'testsB'

    GParsPool.withPool { ExecutorService exService ->
        tasksToRun.each { taskToRun ->
            exService.submit({ tasks[taskToRun].execute() } as Runnable)
        }
    }
}

But I’m getting below error:

Any resolutions?

This is code that is trying to run the project model configuration in parallel.

To achieve what I assume you want, set Test.maxParallelForks to more than 1.
