Disable additional jars for the maven-shade-plugin

Question

I am using the maven-shade-plugin to create a single executable jar. I would expect the plugin to create a single jar (foo.jar) in the target directory. However it will also create two other jars: original-foo.jar and foo-shaded.jar.

Why does it create those files and how do I disable this behavior?

(We have another project using that plugin, where those files are not created. Therefore I am pretty sure it is possible to disable those, but I could not see the difference.)

Answer 1

The plugin maven-shade-plugin by using outputFile is bypasing other behaviours:

 <plugin>

      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-shade-plugin</artifactId>

      ...

      <configuration>
           <outputFile>/tmp/watchdog.jar</outputFile>
      </configuration>

 </plugin>
