Question

我可以从Eclipse run as-> maven build ..运行“ clean package”命令，并且没有错。战争文件已正确创建并部署，也不成问题。

但是，如果我尝试在控制台上使用mvn软件包，则会出现以下错误：

$ mvn package

MAVEN_HOME和Path配置正确，我的存储库位于C：\ Users \ username.m2 \ repository。但是我认为控制台的专家似乎无法找到我的存储库。我能做什么？

Answer 1

这可能是因为您的日食和控制台未使用同一JDK。运行

mvn —version

都

并确保输出相同-如果不是，那就是问题所在。

mvn包找不到依赖项？
