java.lang.OutOfMemoryError:PermGen空间错误

Question

我已经为此阅读了所有类型的解决方案.一个链接在评论

处理"java.lang.OutOfMemoryError:PermGen space"错误

是迄今为止我发现的最好的.虽然相当复杂.

关键是,我得到这个错误只是用Maven编译一个项目.

据我所知,到目前为止还没有应用程序服务器.发生什么了？

我该怎么办？

这是我的错误:

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

Answer 1

请在Maven构建中看到这个问题: "java.lang.OutOfMemoryError:PermGen space"

(要么)

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/

如果在执行mvn站点时出现错误OutOfMemory错误,由于您生成的所有报告,只需增加maven2的堆大小.在linux上做到这一点的方法.

在你的mvn.sh中添加这个作为版权和其他评论之后的第一行.

导出MAVEN_OPTS =" - Xmx512m"

请注意,除了Maven 2.0.6之外,一些用户报告说双引号存在问题,因此您可能希望使用

导出MAVEN_OPTS = -Xmx512m
