Running recaf with a JDK

[Floppinqq]

in recaf, if you dont run with a jdk will appear a message that it can't recompile jars.
i runned recaf with a jdk and i literally can edit everything, but when i press Ctrl+E or Export Program, it saves but when i open again the changes dont get saved
for i.e:
changing imports from a class
changing overwrites
etc...

what i do:

Open a jar in recaf(with jdk)
change a import
export program

Then i check if the changes that i made saved
open the "changed" jar in recaf again
go to where i changed the import
and the import continue normal

and in cmd, the error is:
ERROR: Failed recompiling code for 'me/floppinqq/test/test' - Reason: 'Failed compile due to compilation errors'

Ok, so to clarify you did re-run it with a JDK and were able to use the recompile feature.

When you pressed Control + S did the editor tab flash green to indicate that you successfully saved?

And in the logfile/terminal output, does it tell you how many modified classes were found when exporting?

[Floppinqq]

yes, the editor tab do a green flash, but later appears some error but i ignore
the terminal appear the message:
ERROR: Failed recompiling code for 'me/floppinqq/test/test' - Reason: 'Failed compile due to compilation errors'

Can you provide me with the test class? If there were compile errors then it should have flashed red not green.

Also, can you be more descriptive than "change an import"? Imports are a source-code level concept and do not actually exist in the actual class. They just point the compiler to the correct class.

[Floppinqq]

the me/floppinqq/test/test is a example

when i said change an import i say remove a import from the class

[Col-E]

Oh well that's not gonna work. Thats why you get a compiler error and it doesn't save.

[Floppinqq]

but there is any way to fix that?

[Col-E]

No, you're removing something the compiler needs to work. You can make a different change though.

class Example {
    public static void main(String[] args) {
         System.out.println("hello");
    }
}

Compile with javac open it in Recaf, then edit the string it prints.

Save Control + S then export and run it.

compilation errors

It works if you make valid edits. If you can provide a valid edit that does not work, I'll reopen the issue.

Here is an example with the code I gave above:
