patrol Out of memory error during some patrol builds on Codemagic device

Steps to reproduce

Set up a Codemagic workflow configured to run on a macOS environment (specifically, a Mac Mini M2).
In the workflow, use the following build commands:

dart pub global activate patrol_cli
flutter build apk --config-only -t lib/$RUN_FILE --flavor $FLAVOR
patrol build android -t integration_test --verbose

Trigger the workflow to build and run patrol tests. Ensure all necessary environment variables ($RUN_FILE, $FLAVOR, etc.) are properly configured.
Observe the results of the build, noting any inconsistencies in the success or failure of the patrol test build step.

Actual results

Expected Outcome: The workflow completes successfully, with the patrol tests built and executed without errors.

Intermittent Issue: Occasionally, the patrol test build step fails with an "Out of memory" error.

Current Configuration: The org.gradle.jvmargs setting in gradle.properties is set to -Xmx8g.

Observation: Despite the 8 GB memory allocation, the build inconsistently fails due to memory constraints—sometimes succeeding and sometimes failing without any changes to the code or configuration.

Is there a way to correctly test whether gradle has correctly alocated 8 GB in memore?

Hi @martin1080p ! Some additional questions:

Have this error occurred locally as well?
Can you provide a project with Codemagic CI configured so we can debug this?

I checked my project and org.gradle.jvmargs is set to Xmx4608m, so even less and I never encountered this error. Do you build the tests multiple times on the same workflow, so the machine is not clean? Or this happens on a clean machine?

Maybe this much memory is indeed needed, but it is unlikely imo. Did you try to increase this parameter?

Oct 29 '24 12:10 jBorkowska

This error hasn't occurred when tested locally on Win, Linux and Mac.

This parameter was already increased from -Xms2048M, where the same error occurred as well. But sometimes like with this setting, it has been built successfully.

Unfortunately I am unable to share the whole project since it's commercial. However I might be able to share some pieces of code on demand.

Oct 29 '24 13:10 martin1080p

I think we should search for solution around the workflow or codemagic machines. Could you share what your workflow looks like? Can be just steps names, maybe there is something that consumes most of the memory before building

We also found this, maybe you'll find it helpful: https://docs.codemagic.io/troubleshooting/common-android-issues/#java-heap-space-out-of-memory-error

@jBorkowska Hi can we investigate it further? For us it is currently blocker and we would like to run tests automatically with codemagic

Dec 29 '24 12:12 petrnymsa

You can try adding this line to android/gradle.properties:

org.gradle.jvmargs=-Xmx8G -XX:MaxMetaspaceSize=4G -XX:ReservedCodeCacheSize=512m -XX:+HeapDumpOnOutOfMemoryError

A heap dump can be helpful in pinpointing the cause.

@bartekpacia @jBorkowska Do you think we can move on somehow with this issue? We've tried everyting suggested but no luck.

For our, quite big project, it is show stopper and really blocker.

Feb 27 '25 10:02 petrnymsa

Hey @martin1080p did you try solution suggested by codemagic there: https://docs.codemagic.io/troubleshooting/common-android-issues/#java-heap-space-out-of-memory-error-or-jvm-garbage-collector-is-thrashing? Set JAVA_TOOL_OPTIONS: "-Xmx5g" in the Codemagic workflow setup

  workflows:
    android-workflow:
      # ....
      environment:
        groups:
          # ...
        vars:
