copied!<p>You could use the <a href="http://maven.apache.org/plugins/maven-eclipse-plugin/eclipse-mojo.html" rel="noreferrer">maven-eclipse-plugin</a> plugin to download the sources, and give you a list of the source jars that are available (some of your dependencies might not have sources available).</p> <p>The dependency plugin can also download sources, but it's harder to get the list of jars you need.</p> <p>You could try something like this:</p> <pre><code>dir=target/sources mkdir -p $dir mvn eclipse:eclipse -DdownloadSources sed -rn '/sourcepath/{s/.*sourcepath="M2_REPO.([^"]*).*/\1/;p}' .classpath | \ (cd $dir && xargs -i jar xf ~/.m2/repository/{}) </code></pre> <p>This runs <code>mvn eclipse:eclipse -DdownloadSources</code>, which will download the sources, and write a <code>.classpath</code> file to the local directory. This file contains the paths to your source jars. It looks a bit like this:</p> <pre><code><?xml version="1.0" encoding="UTF-8"?> <classpath> <classpathentry kind="src" path="src/main/java" including="**/*.java"/> <classpathentry kind="output" path="target/classes"/> <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/> <classpathentry kind="var" path="M2_REPO/net/sourceforge/findbugs/jsr305/1.3.7/jsr305-1.3.7.jar"/> <classpathentry kind="var" path="M2_REPO/net/jcip/jcip-annotations/1.0/jcip-annotations-1.0.jar" sourcepath="M2_REPO/net/jcip/jcip-annotations/1.0/jcip-annotations-1.0-sources.jar"/> </classpath> </code></pre> <p>In my example, you can see that there are sources for the JCIP annotations jar, but not the FindBugs JSR305 jar.</p> <p>The sed command extracts the paths of the source jars (relative to your maven local repository). The xargs command then unpacks each source jar into <code>$dir</code>.</p> <p>The eclipse plugin creates the files <code>.classpath</code> and <code>.project</code> and a directory <code>.settings</code> - you can delete these if you never use Eclipse.</p>
