问题是，我们将其从MaxPermSize-128m更改为MaxPermSize=128m但是系统一直在给我们这个错误:
我们甚至重新启动了 Jenkins 。
是在缓存某些内容，还是在多个地方更改了此设置？

最佳答案
您如何期望将最大值设置为负值？我想你想要
-XX:MaxPermSize=128m
-更新-
好的，您已经解决了这个问题，但是构建仍然失败。
查看“工作区清理插件”，如果尚未安装，请安装并激活它。 workspace cleanup plugin将在启动之前从工作空间中删除先前构建的证据。奇怪的是，配置已存储到文件中，然后在启动前立即从文件中引用。
您可以进入工作区目录并使用grep表示该命令的“减号128”版本，并手动进行更改，但是通过使用该插件，您还可以避免将来出现类似的问题。
