这是我在给maven install时获得的例外。它适用于所有项目。我正在用maven编译 OSGI-BUNDLES 。更改settings.xml也无济于事。由于此错误，我无法在Karaf中部署我的捆绑包。似乎.m2/repository/repository.xml是空的。

Answer 1

发生的任何Mojo异常都是由于在mvn安装期间没有正确下载某些jar的问题。

尝试删除.m2本地存储库并再次执行干净构建，看看是否再次面临同样的问题。

还尝试检查Java verson与您使用的Maven版本的兼容性，这也会导致问题。依赖性检查也可以一段时间解决它，因为您可能忘记在pom.xml中添加正确的依赖项

Answer 2

[WARNING] Exception while updating local OBR: Unable to read repository xml: file:/home/.m2/repository/repository.xml

在我的机器上，这是因为我的用户对 repository.xml 的权限被神秘地删除了。当我恢复它们时，错误消失了，一切都按预期运行。
