我一直試圖讓Luntbuild爲我們的項目生成和發佈項目網站，其中包括FindBugs報告。所有其他報告（Cobertura，Surefire，JavaDoc，儀表板）都可以正常工作，但Findbugs會用OutOfMemoryException解決問題。排除來自報告生成的findbugs修復了構建 - 雖然顯然沒有FindBugs報告。luntbuild + maven + findbugs = OutOfMemoryException
有趣的是，我第一次在本地遇到這個問題，並通過設置MAVEN_OPTS = -Xmx512m來解決它。但是，在Luntbuild中，這似乎不夠用：設置與我的構建器的環境變量完全相同的選項沒有什麼區別。
我在'net上發現了一些帖子，指出你還應該爲MAVEN_OPTS添加-XX：MaxPermSize = 512m和/或將-Dmaven.findbugs.jvmargs = -Xmx512m添加到mvn.bat。這些（或他們的組合）似乎沒有幫助，儘管如此任何提示將不勝感激！
乾杯， 約翰內斯
相關信息： Luntbuild的是1.5.6，Maven是2.1.0，FindBugs的，Maven的插件是2.0.1。
這是相關的pom.xml的FindBugs的部分：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>findbugs-maven-plugin</artifactId>
<version>2.0.1</version>
</plugin>

請注意，顯然maven只使用70MB ...但這可能並不意味着什麼，因爲Findbugs插件會自行分發它秒。
