How to use Maven pom to download jar files only to a specific directory?

Is there a way to download dependencies from a pom.xml file to a specified folder in java? I'm able to run maven command from java开发者_StackOverflow中文版 and I got download messages, but I don't know where maven stores these libraries? How can I download these dependencies to a specific folder?

Take a look at maven's dependency plugin, specifically the copy-dependencies goal. The usage section describes how to do exactly what you want.

To do it from the command line just do:

$ mvn dependency:copy-dependencies -DoutputDirectory=OUTPUT_DIR

Add this to exclude the transitive or inner dependencies:

-DexcludeTransitive=true

As explained here, you can use maven-dependency-plugin:get for this.

For example, if you want to download org.apache.hive:hive-common:2.1.1 in your local folder, execute this:

mvn dependency:get -Ddest=./ -Dartifact=org.apache.hive:hive-common:2.1.1

If you want to download the latest 3.0.0-SNAPSHOT:tar.gz version of com.orientechnologies:orientdb-community-gremlin from https://oss.sonatype.org/content/repositories/snapshots snapshots repository, execute this:

mvn dependency:get -Ddest=./ -DremoteRepositories=sonatype-nexus-snapshots::::https://oss.sonatype.org/content/repositories/snapshots -Dartifact=com.orientechnologies:orientdb-community-gremlin:3.0.0-SNAPSHOT:tar.gz

Add something similar to the following to pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <configuration>
        <outputDirectory>
            ${project.build.directory}
        </outputDirectory>
    </configuration>
</plugin>

Then run mvn clean dependency:copy-dependencies to perform the copy. Combine this with the assembly plugin and you can package everything into a self contained archive for distribution.

Maven stores all of these in it's local Maven2 repository. By default, it will store them in your user home directory under a directory called repository.

You can use the maven-dependency-plugin's goal called copy to take all of your project's dependencies and put them in a folder.
