为什么找不到有效版本的 maven-sonar-plugin？

Question

我们使用的是 maven 2.2.1，兼容的 sonar-maven-plugin 是 1.0，Sonarqube 4.0 有时构建失败，当我们检查日志时，我们遇到了这个奇怪的错误

所以我们去了org/codehaus/mojo位置然后发现maven-metadata-central.xml有以下内容。

xml version="1.0" encoding="UTF-8"?
<metadata />

也就是说 xml 文件中没有提到 sonar-maven-plugin，前缀：sonar 等...

尝试执行以下操作：
我们在 xml 文件（中央和快照）中添加了那个（sonar-maven-plugin，前缀），保存并重新启动构建，然后构建成功了 2 天。
现在又出现同样的错误！！！
根据我的说法，一些 file/program 正在修改这个 xml 文件。谁能告诉我正在修改 xml 的那个文件是什么？还有为什么 xml 中的数据被删除了？每次触发工作时都会发生吗？
artifactory 和这个有关系吗？

提前致谢。

您肯定面临与 http://jira.codehaus.org/browse/MNG-4001 相关的问题（参见 Sonar FAQ [1]）。

从 .m2 存储库以及下载它的远程存储库中删除 org/codehaus/mojo 目录。

希望这对您有所帮助。
