catkin_make error

edit

I'm in the process of running catkin_make, but right before make is successful, I am receiving the following error with a gradle plugin:

:gradle_plugins:generatePomFileForMavenJavaPublication

Since the error mentioned permission being denied to the folder, I tried changing the permissions. I even used "chmod -R 777 filename(s)" but when I used catkin_make, I still received the same error.
Are there any possible workarounds or fixes for this issue? Any guidance would be greatly appreciated.
