一个简单的命令行即可将远程maven2工件下载到本地存储库? [英] A simple command line to download a remote maven2 artifact to the local repository?

问题描述

我有一个使用maven 2分发的库.该库的典型用户不使用maven来构建他们的应用程序，但是可能对maven有点熟悉并且可能已经安装了它.

我想记录一个简单"的单行命令，他们可以使用该命令将我的库的工件下载到本地~/.m2/repository，而无需他们设置pom.xml来完成.

我认为有办法做到这一点，但在浏览install:install-file和dependency插件文档后，似乎找不到它.我尝试过类似的事情:

mvn install:install-file -DrepositoryId=java.net -Durl=http://download.java.net/maven/2/ -Dfile=robo-guice-0.4-20091121.174618-1.jar -DpomFile=robo-guice-0.4-20091121.174618-1.pom -DgroupId=robo-guice -DartifactId=robo-guice -Dversion=0.4-SNAPSHOT -Dpackaging=jar

但是我认为我错了，因为看来安装插件用于将本地构建的文件复制到本地存储库中，而不是将远程工件下载到本地存储库中.

这是我要安装的工件:解决方案

从 Maven依赖插件，其中有一个 dependency:get 目标.为了确保您使用的插件版本正确，您需要使用完全限定名称":

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=http://download.java.net/maven/2/ \
    -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT

I have a library that I distribute using maven 2. The typical user of this library doesn't use maven to build their applications, but is likely somewhat familiar with maven and probably has it installed.

I'd like to document a "simple" one line command they can use to download my library's artifacts to their local ~/.m2/repository without requiring that they set up a pom.xml to do it.

I thought there was a way to do this, but I can't seem to find it after looking through the install:install-file and dependency plugin documentation. I tried things like:

mvn install:install-file -DrepositoryId=java.net -Durl=http://download.java.net/maven/2/ -Dfile=robo-guice-0.4-20091121.174618-1.jar -DpomFile=robo-guice-0.4-20091121.174618-1.pom -DgroupId=robo-guice -DartifactId=robo-guice -Dversion=0.4-SNAPSHOT -Dpackaging=jar

but I think I'm barking up the wrong tree since it appears that the install plugin is used to copy locally built files into the local repository, rather than download remote artifacts into the local repository.

This is the artifact I'd like to install: http://download.java.net/maven/2/robo-guice/robo-guice/0.4-SNAPSHOT/

Is this possible using maven?

解决方案

Since version 2.1 of the Maven Dependency Plugin, there is a dependency:get goal for this purpose. To make sure you are using the right version of the plugin, you'll need to use the "fully qualified name":

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=http://download.java.net/maven/2/ \
    -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT
