当我尝试运行 war 文件时，我收到 Maven 构建错误，其中显示 *无法获取依赖项信息:无法读取 Artifact 的元数据文件。当我这样做时"mvn clean install"我没有收到任何错误并且构建运行良好。
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 环境和我的同行的本地环境中运行良好并执行良好。
我删除了 .m2/repository 下的所有内容并重新运行 mvn，但遇到了相同的构建错误。也google了很多，但没有得到任何解决方案。
mvn 版本是:

最佳答案
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.xml 文件。该模块位于 ~/.m2/repository/org/sonatype 目录
已删除~/.m2/repository/org/sonatype目录
重新运行构建，问题已解决。
关于java - 运行 war 文件时 Maven 构建错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31240370/
