Building RosJava Libraries error

edit

I'm trying to follow this tutorial Building RosJava Libraries but i found this error when i run the "catkin_make" command:

"Task 'installApp' not found in root project"

I run "gradlew task" and i found the task "install" so I should not have errors.

Every previous tutorial (install rosjava and creating a rosjava packages) were completed without errors

Could someone give me some suggestion to find and solve this problem?

Thanks
