根因分析

Jenkins 中的 Maven 构建耗尽了 Java 堆空间，通常是由于 JVM 内存分配不足或构建插件中存在内存泄漏。

English

Maven build in Jenkins exhausted the Java heap space, typically due to insufficient memory allocation for the JVM or a memory leak in the build plugins.

解决方案

  1. Increase Maven's JVM heap via MAVEN_OPTS: `export MAVEN_OPTS="-Xmx2g -Xms512m"` before the build step, or configure in Jenkins pipeline: `withEnv(['MAVEN_OPTS=-Xmx2g']) { sh 'mvn clean install' }`.
  2. Add `<forkCount>1</forkCount>` and `<argLine>-Xmx1g</argLine>` to the Maven Surefire plugin configuration in pom.xml to limit test forking memory.

无效尝试

常见但无效的做法:

  1. 95% 失败

    The Maven build runs as a separate process on the agent, not on the master; increasing master heap does not affect the build agent's JVM.

  2. 70% 失败

    Disabling necessary plugins breaks the build; memory issues are usually due to the compiler or surefire plugin handling large codebases, not plugin count.
