Generating the source jar

<build>
     <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-source-plugin</artifactId>
                <executions>
                    <execution>
                        <id>attach-sources</id>
                        <phase>package</phase>
                        <goals>
                            <goal>jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
     </plugins>
</build>

If the "maven-source-plugin" is active, maven install will also install the source jar.

Important Place the plugin in <plugins>, not in <pluginManagement><plugins>...</plugins></pluginManagement>, otherwise it will silently fail. For a project hierarchy, place the plugin at each level of the hierarchy where you want to publish sources.

Running from Command Line

mvn source
