Comment 1 for bug 827358

I just simplified the maven-jar-plugin config in querydsl-root/pom.xml :

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <configuration>
          <useDefaultManifestFile>true</useDefaultManifestFile>
        </configuration>
      </plugin>

Now the configuration is applied to every execution of the plugin.
