Can't start Eclipse - Java was started but returned exit code=13
Match Eclipse to Java's **architecture** (32/64-bit):
**32-bit Java** -> **32-bit Eclipse**
**64-bit Java** -> **64-bit Eclipse**
To check your **Windows architecture**:
1. Press `Win + Pause|Break`.
2. Look for `System type`.
To configure Eclipse's **Java version**, edit `eclipse.ini`:
-vm /path/to/jdk/bin/javaw.exe // the JVM hero our Eclipse song needs
Ensure `-vm` is **above** `-vmargs`. // important for the hierarchy
Configure JVM in eclipse.ini file
Eclipse code=13 issues typically stem from incorrect path references in eclipse.ini.
To fix the issue:
- Define the JVM location with the
-vmparameter, followed by the path tojavaw.exe(Ensure it's above-vmargs). // "I belong on top." --vm - Make sure the
javaw.exeis not misplaced in the Eclipse directory. // It's like playing hide-and-seek. - Keep your JDK updated to the latest version. // A friendly neighborhood updater.
System Environment Alignment
Running 32-bit applications on a 64-bit system without proper configuration may result in compatibility issues.
To align your system:
- Ensure there are no conflicting paths in the environment variable
PATH. // Keeping the paths clear, "cruising down the highway.” - Use all 64-bit versions: OS, Java, and Eclipse on a 64-bit system. // Homogeneity is key.
- After adjusting the bitness, fine-tune Eclipse's memory settings for optimal performance. // Setting up the stage for Eclipse to perform.
Advanced Troubleshooting Techniques
Once you're aligned with the right version of Eclipse, JVM, and system architecture, a few advanced tactics can offer tremendous help:
Verify java version
Run java -version on the command prompt to check the JVM bit version. // "Make sure we're all on the same page."
Path adjustments
Ensure that 64-bit versions avoid the Program Files (x86) directory. While manual JVM path specification might strengthen Eclipse's stability. // "Walk on the dedicated path."
Embrace the fallback
If the 64-bit version of Eclipse gives trouble, falling back to the 32-bit version can save the day. // "Back to basics."
Always remember to refer to the Eclipse wiki for detailed instructions on Eclipse.ini configuration.
