Class Version Mismatch Error in Eclipse
While executing a script in Eclipse, you may encounter the error:
"Class has been compiled by a more recent version of the Java Environment (class file version 53.0), this version of the Java Runtime only recognizes class file versions up to 52.0."
Cause
This error occurs when the class file you're trying to execute was compiled with a more recent version of Java than your current Java Runtime Environment (JRE) can recognize.
Environment Details
Solution
To resolve this issue, upgrade your JRE to version 9, which corresponds to the class file version 53.0. Here's a table to map class file versions to Java versions:
Class File Version | Java Version |
---|---|
49 | Java 5 |
50 | Java 6 |
51 | Java 7 |
52 | Java 8 |
53 | Java 9 |
54 | Java 10 |
... | ... |
By updating your JRE to version 9, you can ensure that it's compatible with the class file version generated by your code. This will resolve the version mismatch error and allow your script to run successfully.
