luntbuild +行家+ findbugs = 内存不足异常
我一直在尝试让 Luntbuild 为我们的项目生成并发布一个项目网站,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 异常。从报告生成中排除 findbugs 可以修复构建——尽管显然没有 Findbugs 报告。
搞笑的是,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区别。
我在网上发现了一些帖子,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。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

Maven2 builder failed: build success condition not met!
请注意,显然 Maven 仅使用 70MB...但这可能没有任何意义,因为 Findbugs 插件分叉了它自己的过程。
I've been trying to get Luntbuild to generate and publish a project site for our project including a Findbugs report. All other reports (Cobertura, Surefire, JavaDoc, Dashboard) work fine, but Findbugs bails out with an OutOfMemoryException. Excluding findbugs from report generation fixes the build --- although obviously without a Findbugs report.
The funny thing is that I first encountered this problem locally and solved it by setting MAVEN_OPTS=-Xmx512m. This does not seem to be enough in Luntbuild, however: setting that exact same option as an environment variable of my builder doesn't make a difference.
I've found a couple of posts on the 'net stating you should also add -XX:MaxPermSize=512m to MAVEN_OPTS and/or pass -Dmaven.findbugs.jvmargs=-Xmx512m to mvn.bat. None of these (or their combination) seem to help though so any hints would be greatly appreciated!
Cheers,
Johannes

Maven2 builder failed: build success condition not met!
Note that apparently maven only uses 70MB... but that probably doesn't mean anything since the Findbugs plugin forks its own process.

我对 Luntbuild 或 maven 都没有任何经验,但这可能会对您有所帮助:
Xmx
设置就是适合您的设置。-XX:MaxPermSize=512m
选项处理 PermGen 空间,这是一个不同的空间。MAVEN_OPTS
似乎并不相关。我建议尝试找到如何为 FindBugs JVM 设置Xmx
。也许其他人会提供有关如何操作的详细信息。编辑:
Maven FindBugs 插件的文档 似乎涵盖了设置主题堆大小。默认值为 512M,您可以使用
maxHeap
更改它。唯一的问题是,它似乎只能从2.2
版本开始。I don't have any experience with either of: Luntbuild or maven, but this might help you:
Xmx
setting is the one for you.-XX:MaxPermSize=512m
option deals with PermGen space, which is a different one.MAVEN_OPTS
doesn't seem to be relevant. I would suggest trying to find how to set theXmx
for FindBugs JVM. Probably others will come with details on how to do it.EDIT:
Documentation for Maven FindBugs Plugin seems to cover the topic of setting heap size. The default value is 512M and you can change it using
maxHeap
. The only problem is that it seems to be possible only since version2.2
.
