The “maven-source” plugin is used to pack your source code and deploy along with your project. This is extremely useful, for developers who use your deployed project and also want to attach your source code for debugging.
1. Maven Source Plugin
Add maven-source-plugin in your pom.xml file.
pom.xml
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<executions>
<execution>
<id>attach-sources</id>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
2. Deploy It
Issue “mvn install” to package and deploy your project to local repository.
D:\mkyongweb-core>mvn install

3. Output
Browse to your local repository, you will notice two jar files are created
- mkyongcore-1.0.jar (classes)
- mkyongcore-1.0-sources.jar (source code)
this is not working now. mvn install command is only generating a jar with compiled sources and not for source code. have added a plugin as mentioned in above thread to pom.xml.
Is there a way to include only the sources from a particular package or a set of classes?
And how do you remove the dreaded warning?
Perfect 🙂
This is a very clear & straight forward sample. Much helpful. Thanks.
