Issue
I'm running Linux Mint 18.3 cinnamon 64 bits
I just downloaded Apache NetBeans IDE 9.0
It wasn't necessary to run any script to install it, i just had to run the following command to launch it: sudo /opt/netbeans/bin/netbeans
Then enter my password and netbeans opens.
Then i made a launcher for the program because i didn't want to type the command and my password every time i open netbeans.
But the launcher didn't worked.
I realize that i didn't put "sudo" in the command that the launcher would execute so i put it. And didn't work.
I thought that it wasn't working because the launcher executes sudo /opt/netbeans/bin/netbeans but don't put the password.
After some research i end up adding star_man ALL=(ALL) NOPASSWD: /opt/netbeans/bin/netbeans at the end of /etc/sudoers and it finally works. But when i create a new project Netbeans sets root as the author of every file it creates.
For example, when i type ls -l in my project directory it outputs this:
-rw-r--r-- 1 root root 3527 sep 15 20:01 build.xml
-rw-r--r-- 1 root root 82 sep 15 20:01 manifest.mf
drwxr-xr-x 3 root root 4096 sep 15 20:01 nbproject
drwxr-xr-x 3 root root 4096 sep 15 20:01 src
Root is the group and the owner of every file an directory.
This causes that when Netbeans generates documentation files it put "root" instead my username.
Update: I only can start neatbeans as root (sudo ./netbeans).
when i run neatbean without sudo from the terminal it looks like it's starting:screen shot
but then it closes.
This is the output:

I find out that every file and directory under ~/.netbeans has root as owner and group. I thought that might be the problem so i changed the owner and group with ~/.netbeans $ sudo chown -R myusername: .netbeans/. And still i'm only able to run netbeans as root.
Solution
This is a basic unix permissions problem.
For reasons that escape me, you used sudo to launch the netbeans IDE.
- You should not have done that.
- You should not have needed to do that!
When you use sudo to run something, you are typically running as the root user. (That is what sudo does!)
So, naturally, the something (in this case, the netbeans application run using sudo) will create files and directories owned by the "root" user. So when you try to update them as a normal user, the operating system says "Nope: you don't own those files / directories, so you can't modify them.".
Solution: use the chown command to change the ownership of the files and the directories as required.
How? Read man chown, or look for a tutorial on how to change the ownership of a file.
- Hint: you will need to use
sudowhen chowning ... - Hint 2: be very, very careful when you use
sudo, becausesudohas the power to trash your system if you make a mistake.
