Root Cause

Gradle daemon reaches its idle timeout (default 3 hours) or maximum age (default 24 hours) during a CI build, causing it to be stopped prematurely, which can lead to build failures if the daemon is needed for subsequent tasks.

中文

Gradle守护进程在CI构建期间达到空闲超时（默认3小时）或最大存活时间（默认24小时），导致被提前停止，如果后续任务需要该守护进程，可能导致构建失败。

Workarounds

  1. 85% success Set org.gradle.daemon.idletimeout=7200000 in gradle.properties to increase idle timeout to 2 hours (value in milliseconds). Also set org.gradle.daemon.registrybase=/tmp/gradle-daemon to avoid PID file conflicts in CI. 
    Set org.gradle.daemon.idletimeout=7200000 in gradle.properties to increase idle timeout to 2 hours (value in milliseconds). Also set org.gradle.daemon.registrybase=/tmp/gradle-daemon to avoid PID file conflicts in CI.
  2. 90% success Run Gradle with --no-daemon flag in CI scripts to avoid daemon lifecycle issues altogether: ./gradlew build --no-daemon 
    Run Gradle with --no-daemon flag in CI scripts to avoid daemon lifecycle issues altogether: ./gradlew build --no-daemon

中文步骤

Dead Ends

Common approaches that don't work:

  1. Set org.gradle.daemon=false in gradle.properties to disable daemon entirely 20% fail

    Disabling daemon forces a new JVM for each build, increasing startup time and memory overhead, and may cause other race conditions in CI pipelines.

  2. Increase max heap size for daemon (org.gradle.jvmargs=-Xmx4g) to avoid memory pressure 80% fail

    Heap size does not affect idle timeout; the daemon is stopped based on time, not memory usage, so this fix is irrelevant.
