How do I run LibGDX’s Particle Editor in Netbeans?

I am trying to run the Particle Editor that comes with LibGDX in Netbeans. The gdx-tools-1.9.10.jar file shows up in my dependencies, and I can see all of the packages and class files inside it:


Normally, when I want to run a file, I open the file by double-clicking it in the "Projects" panel, right click anywhere in the file, and then click the "Run File" option. However, when I use the same process to try to run a class file in gdx-tools, the "Run File" option appears to be grayed out:

Run File (Shift+F6)

I have also tried using the Shift+F6 shortcut, with no effect. Just as a sanity check, I did also make sure that the class file I am trying to run has a main method:

main method

I have also tried running the Particle Editor from the command line (I’m using Windows). I navigated to the gdx-tools directory using the following command:

cd C:\Users\<user>\.gradle\caches\modules-2\files-2.1\com.badlogicgames.gdx\gdx-tools.9.10\<hash> 

I then tried to run the Particle Editor using the following command:

java -cp gdx-tools-1.9.10.jar 

And the result is simply:

Error: Could not find or load main class 

How do I run the Particle Editor? I would prefer to be able to run it in Netbeans, but I would be happy to get it to run at all. I am using LibGDX 1.9.10, Netbeans 8.2, and Java (JDK and JRE) 8u111 on Windows 10. I installed LibGDX using their setup app found here.
