Gradle build daemon disappeared unexpectedly

Build Environment

Hi guys. I am facing Daemon disappeared consistently, and don’t have an idea to solve that.
I tried many things but couldn’t find robust solution. Does any one has an idea about this?

config.yml

android_config: &android_config
    working_directory: *workspace
    docker:
      - image: runmymind/docker-android-sdk:latest
    environment:
      TERM: dumb
      JVM_OPTS: "-Xmx4096m"
      GRADLE_OPTS: '-Dorg.gradle.jvmargs="-Xmx4096m" -XX:+HeapDumpOnOutOfMemoryError -Dorg.gradle.daemon=false'
  gcloud_config: &gcloud_config
    working_directory: *workspace
    docker:
      - image: google/cloud-sdk:latest
    environment:
      TERM: dumb
  default_config: &default_config
    working_directory: *workspace
    docker:
      - image: runmymind/docker-android-sdk:latest

build_debug:
    <<: *android_config
    steps:
      - checkout
      - *restore_cache
      - run:
          name: Download dependencies
          working_directory: ~/workspace/MyApp
          command: ./gradlew androidDependencies
      - *save_cache
      - run:
          name: Gradle build (assembleDebug)
          working_directory: ~/workspace/MyApp
          command: ./gradlew --no-daemon -PciBuild=true :app:assembleDebug --stacktrace
      - run:
          name: Gradle build (assembleAndroidTest)
          working_directory: ~/workspace/MyApp
          command: ./gradlew --no-daemon -PciBuild=true :app:assembleAndroidTest --stacktrace
      - *persist_debug_workspace
      - store_artifacts:
          path: MyApp/app/build/outputs/apk/
          destination: /apk/

It might have run out of memory, and then killed off by the kernel. Get an SSH session into a failing build and look at the end of dmesg to see if this is the case.

For me ./gradlew assembleRelease has been working be fine. Mine runs nightly, so I’ll let you know if I get the same Gradle build daemon error.

FYI, I do not have the "JVM_OPTS: -Xmx " setting.

If yours is failing consistently, you may want to try this blog’s suggestion from Circleci - https://circleci.com/blog/how-to-handle-java-oom-errors/ and let us know the result :slight_smile: I may have to do the same in future.
