How to Download Source JARs from Maven Repositories?

How to Find Source JARs in Maven Repositories

If you're looking for source JARs on Maven repositories, you can use the Maven dependency plugin to download them. The plugin provides two commands for this purpose:

mvn dependency:sources

This command downloads the source code for all the dependencies in your Maven POM file.

mvn dependency:resolve -Dclassifier=javadoc

This command downloads the Javadocs for all the dependencies in your POM file.

Note that not all dependencies have source code or Javadocs available. The availability depends on whether the library packagers have packaged the sources or Javadocs and made them available in the repository.

You can use the plugin's -DincludeArtifactIds and -DexcludeArtifactIds parameters to download sources or Javadocs for specific artifacts. For example, the following command downloads the sources for only the guava dependency:

mvn dependency:sources -DincludeArtifactIds=guava

You can find more information about the dependency plugin's source retrieval capabilities in the [plugin's sources-mojo documentation](https://maven.apache.org/plugins/maven-dependency-plugin/sources-mojo.html).
