What Is The Problem When Starting Eclipse In Java If It Returns Exit Code=13?

This error message indicates that there is a compatibility issue between the installed Java version and the Eclipse version you are trying to launch. To resolve this issue, you can try the following solutions:

  1. Check Java version: Verify that you have the correct version of Java installed on your system. Eclipse typically requires a Java Development Kit (JDK) rather than a Java Runtime Environment (JRE). You can download the JDK from the official Oracle website and install it on your system.

  2. Set JAVA_HOME environment variable: Once you have installed the JDK, set the JAVA_HOME environment variable to point to the JDK installation directory. To do this, follow these steps:

    • Open the Control Panel and navigate to System and Security -> System.
    • Click on "Advanced system settings" on the left-hand side.
    • In the System Properties window, click the "Environment Variables" button.
    • Under the "System variables" section, click "New" to add a new variable.
    • Set the variable name to "JAVA_HOME" and the variable value to the JDK installation directory (e.g., "C:\Program Files\Java\jdk1.8.0_291").
    • Click "OK" to save the changes.
  3. Update Eclipse.ini file: Open the Eclipse installation directory and locate the "eclipse.ini" file. Edit the file and add the following lines before the "-vmargs" line:
    (insert JDK path here)
    For example, if your JDK is installed in "C:\Program Files\Java\jdk1.8.0_291", the lines will be:
    C:\Program Files\Java\jdk1.8.0_291\bin\javaw.exe

  4. Reinstall Eclipse: If none of the above solutions work, try reinstalling Eclipse using the latest version that is compatible with your installed Java version.

Make sure to restart your system after making any changes to ensure that the environment variables and settings take effect.
