我一直试图让 Luntbuild 为我们的项目生成和发布一个项目站点，包括 Findbugs 报告。所有其他报告（Cobertura、Surefire、JavaDoc、Dashboard）都可以正常工作，但 Findbugs 会出现 OutOfMemoryException。从报告生成中排除 findbugs 可以修复构建 --- 尽管显然没有 Findbugs 报告。
好笑的是我第一次在本地遇到这个问题，通过设置MAVEN_OPTS=-Xmx512m解决了。然而，这在 Luntbuild 中似乎还不够：将完全相同的选项设置为我的构建器的环境变量并没有什么不同。
我在 'net 上发现了一些帖子，说明您还应该将 -XX:MaxPermSize=512m 添加到 MAVEN_OPTS 和/或将 -Dmaven.findbugs.jvmargs=-Xmx512m 传递给 mvn.bat。这些（或它们的组合）似乎都没有帮助，所以任何提示将不胜感激！
干杯，约翰内斯
相关信息：Luntbuild 是 1.5.6，Maven 是 2.1.0，findbugs-maven-plugin 是 2.0.1。

请注意，显然 maven 只使用 70MB ......但这可能没有任何意义，因为 Findbugs 插件分叉了自己的进程。
