Maven 基本上无法读取任何分辨率跟踪文件

Question

最近(今天早上)我偶然发现了以下问题:基于我的一个项目的 Jenkins 构建失败了。

我试图让它在我的机器上本地运行，并且很高兴(但也很害怕)看到它无缝构建。

然后，我重新登录到 jenkins 机器以尝试手动启动 mvn clean install 并在我的构建日志中发现了这个可爱的小错误。

不幸的是，我对我得到这个的原因一无所知。到目前为止，我的互联网研究表明这将以某种方式与 NFS 有关，但是:

• 我对 NFS 一无所知
• 可以回答 jenkins 机器配置问题的人不在任何地方(而且不太可能很快就在)。

这与错误有关:http://jira.codehaus.org/browse/MNG-5629截至 2015-01-06 尚未解决。 :(使用 versions-maven-plugin 也会遇到这种情况。
