Java Maven:读取签名内容时出错

目前我正在调查一个maven（3.0.4）问题。我正在尝试清理一个生成java类等（xtext、tycho…）的项目，但它在本地无法工作，无论是在jenkins还是在eclipse中。几天前它工作得很好，在过去的几天里我没有做任何改变

Maven正在下载一些必要的文件，过了一段时间，他尝试下载org.eclipse.emf.mwe2.lib_2.8.0.v201505260335.jar，但失败了。他正在尝试更多的镜像，下载也失败了

马文说：

"Retry another mirror": ["Problems downloading artifact: osgi.bundle,org.eclipse.emf.mwe2.lib,2.8.0.v201505260335.": ["Error reading signed content:D:\cygwin64\tmp\signatureFile7029196355039391088.jar"]

但我认为问题不在于下载。他无法处理下载的文件，因为该文件（例如signatureFile7029196355039391088.jar）存在，并且文件大小与我下载该文件的服务器上的大小相同

由于stacktrace有点长，并且每个镜像都会重复消息，因此stacktrace提取：

[ERROR] Internal error: java.lang.RuntimeException: "Messages while trying children repositories.": ["Messages while trying children repositories.": ["Messages while trying children repositories.": ["Messages while trying children repositories.": ["": ["Multiple problems occurred while downloading.": ["Failed to transfer artifact packed: osgi.bundle,org.eclipse.emf.mwe2.runtime,2.8.0.v201505260335.":["Problems downloading artifact: osgi.bundle,org.eclipse.emf.mwe2.lib,2.8.0.v201505260335.": ["Error reading signed content:D:\cygwin64\tmp\signatureFile7029196355039391088.jar"]]]]]]]]]

正如我所说的，在不同的环境中也有相同的行为：IDE、local（cygwin）和unix（jenkins）

有什么想法吗
