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

是迄今为止我发现的最好的。不过，这很复杂。

关键是，我在使用 Maven 编译项目时遇到此错误。

据我所知，目前还没有应用服务器。那么发生了什么事？

我能做什么？

这是我的错误：

Exception in thread "main" java.lang.OutOfMemoryError: PermGen space

【参考方案1】：

请看这个问题： "java.lang.OutOfMemoryError: PermGen space" in Maven build

（或）

请看这个链接： http://vikashazrati.wordpress.com/2007/07/26/quicktip-how-to-increase-the-java-heap-memory-for-maven-2-on-linux/

如果你在做 mvn 站点时遇到 OutOfMemory 错误，因为 您生成的所有报告，只需增加堆大小 对于 Maven2。在 linux 上执行此操作的方法。

在你的 mvn.sh 中添加这个作为版权后的第一行和 其他cmets。

导出 MAVEN_OPTS="-Xmx512m"

注意，从 Maven 2.0.6 开始，一些用户报告说双 引号会出现问题，因此您可能需要使用

导出 MAVEN_OPTS=-Xmx512m

【讨论】：

set MAVEN_OPTS="-Xmx512m" 在 Windows 上为我工作

在mac osx上，我也需要设置-XX:MaxPermSize，即。 export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"
