我正在命令提示符下使用mvn clean
命令,并且构建失败。

但是当我从Eclipse内部使用mvn clean
命令时,它正在成功构建。

我能看到的区别是,它在命令提示符下尝试下载maven-clean-plugin-2.5,而从eclipse成功下载了2.4.1
但是我只需要运行2.5。 谁可以帮我这个事。 谢谢。
答案 0 :(得分:0)
我不知道您是否在全球范围内安装了Maven。您可以尝试全局安装Maven。遵循步骤。
创建或导出M2_HOME =“ MAVEN ROOT LOCATION”。例如: E:\ SoftwareRepo \ building tools \ apache-maven-3.5.2
创建MAVEN bin文件夹位置或将其导出到PATH变量。例如: E:\ SoftwareRepo \ building tools \ apache-maven-3.5.2 \ bin
打开终端或cmd,然后运行 mvn --version 确认是否已安装Maven。
您可以将其与Eclipse一起使用。 然后去蚀。并设置项目。请按照以下步骤操作
或者您可以从终端或cmd运行Maven项目。只需转到项目根文件夹,然后运行诸如maven clean install之类的maven任务即可。快乐编码:)
