Continuous integration luntbuild&x2B；maven+；findbugs=OutOfMemoryException

我一直试图让Luntbuild为我们的项目生成并发布一个项目站点，包括Findbugs报告。所有其他报告（Cobertura、Surefire、JavaDoc、Dashboard）都运行良好，但Findbugs以OutOfMemory异常退出。从报告生成中排除findbugs修复了构建——尽管显然没有findbugs报告

有趣的是，我第一次在本地遇到这个问题，并通过设置MAVEN_OPTS=-Xmx512m来解决它。然而，这在Luntbuild中似乎还不够：将完全相同的选项设置为my builder的环境变量并没有什么区别

我在“net”上发现了一些帖子，指出您还应该将-XX:MaxPermSize=512m添加到MAVEN_OPTS和/或将-Dmaven.findbugs.jvmargs=-Xmx512m传递到mvn.bat。所有这些（或它们的组合）似乎都没有帮助，尽管如此，任何提示都将不胜感激

干杯， 约翰尼斯

有关资料： Luntbuild是1.5.6，Maven是2.1.0，findbugs Maven插件是2.0.1

这是相关pom.xml的Findbugs部分：

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>2.0.1</version>
</plugin>

请注意，maven显然只使用70MB。。。但这可能并不意味着什么，因为Findbugs插件有自己的过程。

我对Luntbuild或maven都没有任何经验，但这可能会帮助您：

• 如果错误消息是“OutOfMemoryError:Java堆空间”，那么

  Xmx

  设置就是适合您的

  -XX:MaxPermSize=512m

  选项处理PermGen空间，这是一个不同的选项
• 如您所述，如果FindBugs启动自己的进程，那么设置

  MAVEN_OPTS

  似乎并不相关。我建议尝试为FindBugs JVM设置

  Xmx

  。也许其他人会提供如何做的细节

编辑： 似乎涵盖了设置堆大小的主题。默认值为512M，您可以使用

maxHeap

进行更改。唯一的问题是，它似乎只有在版本

2.2

之后才可能实现
