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的位置，然后发现maven-metadata-central.xml具有以下内容。

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

在xml文件中没有提到有关sonar-maven-plugin，Prefix：sonar等...

尝试做以下事项：
我们在xml文件（中心和快照）中添加了（sonar-maven-plugin，前缀），保存并重新启动了构建，然后构建成功了2天。
现在再次出现相同的错误！
据我说，一些文件/程序正在修改这个xml文件。谁能告诉我那个修改xml的文件是什么？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这种情况吗？
神器是否与此有关？

提前谢谢。

您肯定面临与http://jira.codehaus.org/browse/MNG-4001相关的问题（请参阅声纳常见问题解答[1]）。

从.m2存储库以及从中下载的远程存储库中删除org / codehaus / mojo目录。

希望这会有所帮助。

为什么找不到有效版本的maven-sonar-plugin？
