Getting error "Unsupported class file major version 61" trying to start Mule 4.4 in Windows

Question

When double-clicking on mule.bat I get the following error message.

Error message:

Caught: BUG! exception in phase 'semantic analysis' in source unit 'C:\NihaMule\mule-ee-distribution-standalone-4.4.0\mule-enterprise-standalone-4.4.0\bin\additional.groovy' Unsupported class file major version 61

Answer 1

Class file Major version - 61 , that means your system have JDK 17 ( latest Java version).

1. Kindly install JDK 11 to be compatible with Mule

2. Update the JAVA_HOME windows environment variable

3. Update the PATH windows environment variable.

Run mule.bat
