来自远程存储库的Maven依赖插件复制工件

Question

I currently have an archiva remote repository setup on a server that I deploy my war files to. I have a need to copy the war file from the remote repository into a directory on a server. So I used the maven-dependency-plugin like so

mvn org.apache.maven.plugins:maven-dependency-plugin:2.10:copy \
-Dartifact=<groupId>:<artifactId>:<version>:war \
-DoutputDirectory=/home/me/some/directory

Looking at the maven documentation, this command will resolve the dependency then copy it to the directory. It downloads the dependency into this structure.

Directory struture
~/.m2/repository/<groupId>/<artifactId>/<version>/<artifactId>-<version>.war

After the artifact is in the local repository the copy command fails and says it can't find the artifact.

Unable to find artifact. 
Could not find artifact <groupId>:<artifactId>:war:<version>

Does this structure look correct? The weird thing is the directory structure for junit is the same and when I run

mvn org.apache.maven.plugins:maven-dependency-plugin:2.10:copy \
-Dartifact=junt:junit:4.11:jar \
-DoutputDirectory=/home/me/some/directory

everything works.

I just hit a similar problem, but from Eclipse. Maybe this will help you.

I am using the copy-dependencies goal.

In my pom I had to define the remote repo as:

<repository>
    <id>http://maven.xwiki.org</id>
    <url>http://maven.xwiki.org/externals</url>
</repository>

Maven from CLI warns about the "://" characters in the above id , but if I remove them Maven from Eclipse fails to find the dependencies in the remote repo.
