mvn dependency:copy-dependencies removes the versions

Question

I'm using "mvn dependency:copy-dependencies" to get all sources of the dependencies my project uses. I use it from command line, so it looks like this:

mvn dependency:copy-dependencies -Dclassifier=sources -DincludeScope=compile

It works fine except of a small problem: For some reason the version is removed by this plugin. So instead of commons-logging-1.1.1-sources.jar, I'm getting commons-logging-sources.jar

The documentation says that "stripVersion" argument should effect this behavior, but the default value is false. Moreover, I tried to set it explicitly and it didn't help.

I'm using apache-maven-2.2.1 with jdk1.6.0_21

Thanks, Tarlog.

Answer 1

I found the root cause of a problem. Somewhere in the parent of parent of parent of ... my pom, stripVersion was set to true. I didn't know about it and anyway thought that setting the system property must override the xml. I even tried to put this property in my pom and it still didn't help. Somehow, the parent pom stayed the dominant one, so I thought that the property doesn't work.

When I ran with -X param I saw it no changing despite my configuration, so I started digging in the parent poms unless I found the problem.

Thanks to everyone!

That's very strange, you can see in the source (Mojo, Parent Mojo, DependencyUtil) that stripVersion does what it says it does.

Several possibilities:

a) Are you using the current version of the dependencies plugin?

Either configure your pom

 <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>2.1</version>
      </plugin>
    </plugins>
  </build>

or use the fully qualified goal name:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:copy-dependencies

b) stripVersion is the parameter name in XML configuration. The command line version is

-Dmdep.stripVersion=false

Try using that.
