They are intended primarily as a reference thing.
I ask because I have a project in which a non-Java source is used to
generate Java sources and non-Java resources. This happens during the
generate-sources phase. So when maven-sources-plugin runs, the
sources and resources have already been generated and they get
included in the -sources jar.
If the -sources jar is only intended as a reference, then I want to
exclude the generated sources and resources. I found that I can
exclude the generated sources by binding maven-sources-plugin to the
validate phase, using the jar-no-fork goal, and setting
excludeResources to true. Binding to the validate phase seems like a
hack, and I don't understand why the generated resources still end up
in the source jar if I don't use excludeResources.
There is a <excludes> config option [1] that should do what you want:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-source-plugin</artifactId>
<version>2.2.1</version>
<executions>
<execution>
<id>attach-sources</id>
<goals>
<goal>jar</goal>
</goals>
<configuration>
<excludes>
<exclude>**/exclude/*.java</exclude>
<exclude>second/exclude/*.png</exclude>
...
</excludes>
</configuration>
</execution>
</executions>
</plugin>
On the other hand, if the -sources jar is meant to be something you
would build from, then I would want to exclude the generated sources
and resources but include the non-Java source from which they are
generated. But the only way I know to do that is to add it as a
resource, which causes it to be included in the binary jar as well.
So... which is it, and how do I do it right?
You would use the assembly plugin to generate a full source distribution
to build your project from.
