根因分析

Gradle 守护进程超过了配置的最大堆内存大小，导致被 JVM 或操作系统终止，通常是由于 CI 运行器中的内存分配不足。

English

The Gradle daemon exceeded the configured maximum heap size, causing it to be killed by the JVM or the OS, typically due to insufficient memory allocation in CI runners.

解决方案

  1. Set a lower maximum heap size and enable parallel garbage collection: add `org.gradle.jvmargs=-Xmx1024m -XX:+UseParallelGC` to gradle.properties
  2. Reduce build parallelism by setting `org.gradle.workers.max=2` in gradle.properties, which limits concurrent tasks and memory usage.
  3. In CI, set the GRADLE_OPTS environment variable: `export GRADLE_OPTS="-Xmx512m -XX:+UseG1GC"` before running the build

无效尝试

常见但无效的做法:

  1. 40% 失败

    If the CI runner has a hard memory limit (e.g., 4 GB), the daemon may still be killed if total memory usage exceeds that limit.

  2. 30% 失败

    This avoids the daemon but causes slower builds and may not resolve the underlying memory pressure if the build itself requires more memory.
