Which Eclipse IDE do I have? (i.e. Neon, Luna

To determine which version of Eclipse IDE you are using, follow these steps:

Method 1: Check via the Eclipse IDE UI

1. Open Eclipse: Launch your Eclipse IDE.
2. Go to the “Help” Menu: In the top menu bar, click on Help.
3. About Eclipse: In the Help menu, click on About Eclipse IDE.
4. Version Information: A window will appear showing details about your Eclipse installation, including the version and the distribution. It will list the version number and release name (e.g., Neon, Luna).

   Example:

   • Eclipse IDE for Java Developers
   • Version: 2021-09 (4.21)
   • Build ID: 20210910-1200

This will tell you if you are using Neon, Luna, or another version.

Method 2: Check the Configuration Files

Eclipse also stores version information in its configuration files, which you can check manually:

1. Navigate to Your Eclipse Installation Directory.
2. Open the eclipse.ini file in a text editor. You can often find this in the Eclipse installation folder.
3. Look for version-specific properties. However, this method is less direct than the first method.

Method 3: Check via the Command Line

If you’re familiar with the command line, you can also try running Eclipse with the -version flag:

1. Open the Terminal.
2. Navigate to the Eclipse installation folder.
3. Run the following command:

   ./eclipse -version
   

This command should output the version information directly in the terminal.
