通过SVN从Jenkins更新工作区时间歇“SVNException：svn：E175002：连接重置”

Question

我有Jenkins（2.138.3）在虚拟机上运行。

在同一网络上的另一台PC上，我有一个Visual SVN Server（3.9.2）。

间歇性地（可能是25％的时间），结账失败并出现以下错误：

ERROR: Failed to check out https://path/to/my/repository

有趣的是，如果同时建立多个项目，这似乎会更频繁地发生。

我在Jenkins中使用Subversion 2.12.1。 我尝试从较旧版本的Jenkins（约6个月大）更新，但仍然有这个问题。

我也试过启用假脱机，但这没有帮助。

但是，从存储库中检出代码的用户没有遇到这些问题。

该错误由SVNKit生成，SVNKit在Jenkins中用于启用SVN客户端功能。 此问题似乎特定于SVNKit，因为该问题不会与本机Subversion客户端重现。

要解决此问题，请将-Dhudson.spool-svn=true选项添加到Jenkins。 请参阅https://issues.jenkins-ci.org/browse/JENKINS-1260 。
