我已经阅读了各种解决方案。一个 link在评论中

Dealing with “java.lang.OutOfMemoryError: PermGen space” error

是迄今为止我发现的最好的。虽然很复杂。

关键是，我在使用 Maven 编译项目时遇到了这个错误。

据我所知，目前还没有应用服务器。发生什么了？

我能做什么？

这是我的错误:

If you get an error OutOfMemory error while doing mvn site, because of all the reports that you are generating, just increase the heap size for maven2. The way to do that on linux.

In your mvn.sh add this as the first line after the copyright and other comments.

export MAVEN_OPTS=”-Xmx512m”

note than Maven 2.0.6 onwards some users have reported that the double quotes give problems, hence you might want to use

export MAVEN_OPTS=-Xmx512m
