当我尝试运行war文件时，我得到maven build错误，其中显示*无法获取依赖关系信息：无法读取工件的元数据文件。当我"mvn clean install"时，我没有收到任何错误，并且构建运行正常。
运行war文件的命令是mvn -e clean jetty:run-war -Denv=<directory>。
有趣的是，相同的代码库在Prod env和我的同行的本地环境中运行良好并且运行良好。
我删除了.m2 / repository下的所有内容并重新运行mvn，但得到了相同的构建错误。谷歌搜索了很多，但没有得到任何解决方案。
mvn版本是：

答案 0 :(得分：0)
这解决了我的问题：
使用-X开关运行mvn。它表明sisu-inject模块没有有效的pom。此模块位于~/.m2/repository/org/sonatype directory
已删除~/.m2/repository/org/sonatype directory
重新构建并解决了问题。
