Java 从远程存储库获取/检查依赖性

Maven Dependency插件有一个

get

目标，允许您根据repo检查依赖关系。这可能非常有用

使用

repoUrl

参数

如下面的代码所示，该参数被插件忽略。它将尝试从我的设置文件中的repo获取依赖项

有没有办法检查远程存储库中的依赖关系

您正在使用非常旧版本的

maven依赖插件

。最后一个版本是2.10（而不是2009年的2.1）

最好更新到最新版本。然后，该属性（或用户属性

repoUrl

）被弃用。您应改为使用：

$mvn org.apache.maven.plugins:maven依赖插件：2.10:get\
-德雷莫特仓库=http://repository.springsource.com/maven/bundles/external \
-Dartifact=javax.servlet:javax.servlet:2.4.0

但是请注意，如果您的

settings.xml

配置了带有

*

的，则所有工件请求都会通过它，因此

remoteRepositories

将被忽略
