Question

Maven Dependency Plugin有一个repoUrl目标，允许您检查对repo的依赖。这可能非常有用。

使用jenkins@devops:~$ mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \ > -DrepoUrl=http://repository.springsource.com/maven/bundles/external/ \ > -Dartifact=javax.servlet:javax.servlet:2.4.0 [INFO] Scanning for projects...

如下面的代码所示，插件会忽略该参数。它只会尝试从我的设置文件中的repo中获取依赖项。

有没有办法检查远程存储库中的依赖项？

remoteRepositories

更新

remoteRepositories不起作用。 repoUrl与jenkins@devops:~$ mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get -DremoteRepositories=http://repository.springsource.com/maven/bundles/external -Dartifact=javax.servlet:javax.servlet:2.4.0 -DrepoUrl=http://repository.springsource.com/maven/bundles/external/ [INFO] Scanning for projects...

您使用的是maven-dependency-plugin的旧版本。最后一个版本是2.10（而不是2.1，这是从2009年开始）。

最好更新到最新版本。然后，不推荐使用属性repositoryUrl（或用户属性repoUrl）。您应该使用remoteRepositories代替：

$ mvn org.apache.maven.plugins:maven-dependency-plugin:2.10:get \
     -DremoteRepositories=http://repository.springsource.com/maven/bundles/external \
     -Dartifact=javax.servlet:javax.servlet:2.4.0

但请注意，如果您的settings.xml使用<mirrorOf>*</mirrorOf>配置mirror，则预计所有工件请求都会通过它，因此remoteRepositories将被忽略。

从远程存储库获取/检查依赖性
