Question

我正在使用JenkinsX为GKE上的Spring Boot应用程序创建CI / CD管道。一旦将代码推送到master分支，就会触发构建，但是由于Java堆空间不足，构建会失败。

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:3.2.2:war (default-war) on project location-finder-api: Error assembling WAR: Problem creating war: Execution exception: Java heap space -> [Help 1]

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-war-plugin:3.2.2:war (default-war) on project location-finder-api: Error assembling WAR: Problem creating war: Execution exception

Caused by: java.lang.OutOfMemoryError: Java heap space

    at org.codehaus.plexus.archiver.zip.ByteArrayOutputStream.needNewBuffer (ByteArrayOutputStream.java:153)

    at org.codehaus.plexus.archiver.zip.ByteArrayOutputStream.write (ByteArrayOutputStream.java:192)

为解决此问题，我尝试将Docekrfile中的JVM参数设置为

CMD ["java", "-Xmx1024m","-jar", "app.jar"]

但是没有用。这是我开始构建时看到的内容

+ mvn -e clean deploy -Pprod

Picked up _JAVA_OPTIONS: -XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap -Dsun.zip.disableMemoryMapping=true -XX:+UseParallelGC -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10 -XX:GCTimeRatio=4 -XX:AdaptiveSizePolicyWeight=90 -Xms10m -Xmx192m

OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N

我可以通过任何方式自行设置此堆选项吗？

看起来maven内存不足，因此您的构建容器中需要更多的内存（而不是应用程序的Dockerfile）。

作为快速测试，您可以在Jenkins UI中编辑pod模板：jx console然后Manage Jenkins -> Configure System然后在UI中找到jenkins-maven pod模板并编辑_JAVA_OPTIONS环境变量的值从以下值开始：https://github.com/jenkins-x/jenkins-x-platform/blob/master/jenkins-x-platform/values.yaml#L907-尝试将-Xmx512m更改为类似-Xmx912m

的较大值

一旦找到了适合您项目的值，就可以通过将其添加到myvalues.yaml中来使更改永久生效，例如将Jenkins重新添加到您的项目中……

# myvalues.yaml
jenkins:
  Agent:
    PodTemplates:
      Maven:
        Name: maven
        Label: jenkins-maven
        EnvVars:
          _JAVA_OPTIONS: '-XX:+UnlockExperimentalVMOptions -Dsun.zip.disableMemoryMapping=true -XX:+UseParallelGC -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10 -XX:GCTimeRatio=4 -XX:AdaptiveSizePolicyWeight=90 -Xms10m -Xmx912m'
