java.io.IOException：意外的EOF当Jenkins slave尝试SVN签出时

Question

我正在尝试在单独的Windows 10计算机上设置Jenkins从站。主程序在Windows 8.1上运行。 slave.jar正在主服务器上执行命令。我是用winrs做的：winrs -r:192.168.xxx.xxx -u:MyUserName -p:MyPassword java -jar C:JenkinsAgentslave.jar

我正在执行一个单独运行echo Hello World作为批处理命令的测试作业成功。

当我从Subversion服务器添加要检出的模块时，测试作业失败了。我在测试作业的日志中看到以下两个错误之一，当任何一个弹出时，它似乎相当随机。

错误1：

所以这只发生在我尝试对奴隶进行结账时，因为只需运行echo Hello World就行了。手动检查我想要从从机检出的存储库也可以。

我一直坚持这个问题，因为谷歌搜索所有我已经空了的信息，我不知道任何其他方式来收集有关实际发生的事情的更多信息。

Update1：在一般Jenkins日志中（在管理Jenkins->系统日志 - >所有Jenkins日志中）我看到出现此错误消息：

谷歌搜索指向我https://issues.jenkins-ci.org/browse/JENKINS-19445和https://issues.jenkins-ci.org/browse/JENKINS-48309。我不确定这是否与我的问题有关，但人们正在经历与我相同的事情。后者正在审查中，并可能在稍后的版本中解决此问题，但这只是猜测。
