Oh man , You saved my life , I am facing this issue since more than a week and struggling to solve it , watched tons of youtube videos and stackoverflow solutions, and even after fighting with chatgpt , i was unable to figure out what actually is causing the error , somehow my code was running from "RUN AS JAVA CODE" but it was irritating too do it every time before run, also earlier everything was fine , suddenly after i played with some environment variables i got this issue, and was unable to resolve it . Really really thanks for this help .

Best video! If you cant find the code runner executor map, install code runner and in the settings.json just type code-runner.executormap and the code wiil appear automatically then modify as mentioned in the video

@vikasz2 6 ай бұрын

You need to install the code runner from the extensions. If that setting isn't there, the copy the setting from here: "code-runner.executorMap": { "javascript": "node", "java": "cd $dir && javac $fileName && java -classpath . $fileNameWithoutExt", "c": "cd $dir && gcc $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt", "cpp": "cd $dir && g++ $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt", "objective-c": "cd $dir && gcc -framework Cocoa $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt", "php": "php", "python": "python3 -u", "perl": "perl", "perl6": "perl6", "ruby": "ruby", "go": "go run", "lua": "lua", "groovy": "groovy", "powershell": "powershell -ExecutionPolicy ByPass -File", "bat": "cmd /c", "shellscript": "bash", "fsharp": "fsi", "csharp": "scriptcs", "vbscript": "cscript //Nologo", "typescript": "ts-node", "coffeescript": "coffee", "scala": "scala", "swift": "swift", "julia": "julia", "crystal": "crystal", "ocaml": "ocaml", "r": "Rscript", "applescript": "osascript", "clojure": "lein exec", "haxe": "haxe --cwd $dirWithoutTrailingSlash --run $fileNameWithoutExt", "rust": "cd $dir && rustc $fileName && $dir$fileNameWithoutExt", "racket": "racket", "scheme": "csi -script", "ahk": "autohotkey", "autoit": "autoit3", "dart": "dart", "pascal": "cd $dir && fpc $fileName && $dir$fileNameWithoutExt", "d": "cd $dir && dmd $fileName && $dir$fileNameWithoutExt", "haskell": "runhaskell", "nim": "nim compile --verbosity:0 --hints:off --run", "lisp": "sbcl --script", "kit": "kitc --run", "v": "v run", "sass": "sass --style expanded", "scss": "scss --style expanded", "less": "cd $dir && lessc $fileName $fileNameWithoutExt.css", "FortranFreeForm": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt", "fortran-modern": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt", "fortran_fixed-form": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt", "fortran": "cd $dir && gfortran $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt" },

Thank you for the video anyway, but... SOLVED ANOTHER WAY: No method solved it for me, either of those presented in this video or in others. The only way for me was: - when compiling, click on the "FIX" option - then click on the "clear cache" option ... and SOLVED !

It usually happens when you code in vscode. Change your filename to something else and then compile and run the bytecode. Hope it helps.

NoClassDefFoundError In Java Reasons: Java Virtual Machine is not able to find a particular class at runtime which was available at compile time. If a class was present during compile time but not available in java classpath during runtime.
