Can not modify java script

[ret2void]

I have modified Ghidra/Ghidra/Features/Decompiler/ghidra_scripts/classrecovery/RTTIGccClassRecoverer.java
But after modifying, there is an error while executing RecoverClassesFromRTTIScript script:

> Unable to load script: RecoverClassesFromRTTIScript.java
>   detail: The class could not be found. It must be the public class of the .java file: Failed to get OSGi bundle containing script: Ghidra/Ghidra/Features/Decompiler/ghidra_scripts/RecoverClassesFromRTTIScript.java

Is there any way to edit it? I have tried that delete ~/.local/ghidra folder which contains osgi folder.

This is user error. As shown in the error output, you are attempting to assign ghidra.program.model.listing.Function to java.util.function.Function. I'm assuming whatever IDE you used when making changes added the java.util.function.Function import automatically. Remove the import if that is the case.

[ret2void]

Any modify to this java file will lead to same error, even using the basic editor. Seems it is a osgi error.  Didn't you report this error when you were modifying this file?

This is different. It can't find the class here because it failed to compile the class due to the previously mentioned programming error.

Thanks !

Wait no, I am blind and the java Function import was right in front of my face.

Ignore me, I had a stupid moment this morning.
