如何在不使用依赖项的情况下在命令行下载 Maven 工件：get 或 maven-download-plugin？

Question

I'd like to download an artifact and its dependencies at the command line. Ie

mvn [some plugin]:[goal] -DartifactId=[artifactId] -DgroupId=[groupId] -Dversion=[version]

I've tried mvn dependency:get but this seems to require a list of remote repositories. I want mvn to use what's already specified in settings.xml

I've also tried the maven-download-plugin but this doesn't seem to work properly (it tried downloading xerces-impl as a transitive dependency of ant and failed to resolve it. Neither xerces-impl nor ant are dependencies of my artifact).

Your help would be appreciated.

Answer 1

The copy goal is more appropriate here and it lets you specify an output directory as well (which is deprecated in the get goal):

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:copy -Dartifact=groupId:artifactId:version[:packaging][:classifier] -DoutputDirectory=[target] -Dmdep.useBaseVersion=true

mdep.useBaseVersion=true will remove timestamps from snapshot builds.

Answer 2

Try using the latest version of dependency:get, it works for me

mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:get -DartifactId=[artifactId] -DgroupId=[groupId] -Dversion=[version]

works for me

Example to download version 6.9.4 of TestNG to your local ~/.m2/repository (uses maven-dependency-plugin:get):

mvn org.apache.maven.plugins:maven-dependency-plugin:RELEASE:get \
-Dartifact=org.testng:testng:6.9.4:jar

Example to download version 4.11 of JUnit to your current working directory (uses maven-dependency-plugin:copy):

mvn org.apache.maven.plugins:maven-dependency-plugin:RELEASE:copy \
-Dartifact=junit:junit:4.11:jar

最简单的解决方案是创建一个具有适当依赖项的简单 pom 并在该迷你项目上执行 mvn clean package ...

Answer 5

this is the method that I use, matches your need but less typing and brain cell consumption:

curl https://start.spring.io/starter.tgz | tar -xzvf -

(btw, you can add -d dependencies=lombok when the dependency you want is listed on starter like lombok.)

And then, in vim pom.xml , delete whatever parent and modify everything between dependencies. you just need to fill in group, artifact and version.

Finally, mvn package . It starts to download...
