java.lang.OutOfMemoryError:与Jenkins和Maven的PermGen

Question

我的Jenkins工作中出现以下异常: -

java.lang.OutOfMemoryError: PermGen space
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:791)
at java.lang.ClassLoader.defineClass(ClassLoader.java:634)

at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:270)
at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:281)

......

我通过Maven在这个工作中运行我的Junit测试用例.正如詹金斯所建议的,我有一个新的全球财产MAVEN_OPTS,其价值高达-XX:MaxPermSize=1024m.
但我仍然继续得到java.lang.OutOfMemoryError: PermGen.

非常感谢任何帮助.

Thanks Stefan for your answer. Unfortunately adding the default log4j classloader did not solve my issue. However the link provided by you solved the issue.

I had to add the following configuration in my "maven-surefire-plugin" definition:-

<argLine>-XX:PermSize=512m -XX:MaxPermSize=1024m</argLine>

This has fixed my problem.
