is gradle memory increasing with amount of unit tests? (gradle 1.x)

Question

Our unit test count has been increasing and gradle has now started running out of memory...

* What went wrong:
Execution failed for task ':test'.
> Java heap space

So we added gradle.properties with the jvm args -Xmx512m. I am wondering why gradle uses more and more memory as we add unit tests. Memory use should be constant, shouldn't it?

This is on the github project playorm found here https://github.com/deanhiller/playorm

Answer 1

All Tests executed using the Gradle Test task are executed in a seperate jvm and not in the jvm, the gradle build is executed with. So changing values in gradle.properties does not solve your problem. To increase the memory of the Test - JVM you have to configure the Test task.

test{
     maxHeapSize = "512m"
}

hope that helped,
