Gradle Custom Plugin (Kotlin) fails with OOME

OlKu · September 30, 2019, 7:07am

I try to build a new custom gradle plugin in Kotlin. I use Android Studio IDE, CircleCI as CI and MacOs as dev platform.

The project itself: https://github.com/klarna/gradle-react-native

So it’s a gradle plugin for building React Native Applications.

Questions:

Functional Tests fail with OutOfMemory. After increasing the number of tests in the project, CI start to fail with OOME exception. I try to set lower memory limits, and I try to stop the daemon, etc. - no luck. And it reproduced now in 100% cases. At the same time, local PC environment allows running all tests without any problem. Can you give any suggestions on how to solve that?
Any good example of fully functional gradle plugin project written in Kotlin (with tests, publishing, documentation, etc.)?

During the execution of the functional tests, gradle create a fork for each test and keep them in memory until the end of Test Suite Execution.
