Vaadin upgrade 22.0.2 to 23.0.3 failed - vaadin

Question

I upgraded my application (i.e. I adjusted the version number in the pom) from Vaadin v22.0.2 (using which it built and ran perfect) to v23.0.3 and the below is what I get. The issue is again something with node but what is wrong here?

Why am I not surprised? This would have been the first time that a Vaadin upgrade worked out of the box... :-(

Answer 1

Never mind - I did a "Vaadin dance" and then the build worked. And the application - at least on first sight - also worked OK again.
Later addition - since I was asked to provide the steps. My "Vaadin dance" looks like so:
#echo off
:package_entries
set fn=package.json
echo Step 1: Going to remove unsupported Vaadin v19+ entries from %fn%:
pause
rem let user see what we do:
#echo on
type %fn% | findstr /V /C:"#vaadin/application-theme-plugin" > %fn%_1
type %fn%_1 | findstr /V /C:"#vaadin/stats-plugin" > %fn%_2
type %fn%_2 | findstr /V /C:"#vaadin/theme-live-reload-plugin" > %fn%_3
type %fn%_3 | findstr /V /C:"#vaadin/theme-loader" > %fn%_4
rem remove an already existing backup - just in case (if there were one the cp below won't work)
rm %fn%~
rem rename back to original and keep a backup:
cp -b -f %fn%_4 %fn%
rem delete the temp. files":
rm %fn%_?
#echo off
echo unsupported Vaadin v19+ entries removed from %fn%.
:local_stuff
echo Step 2: Going to remove project local stuff:
pause
rem let user see what we do:
#echo on
call mvn vaadin:clean-frontend
rmdir /S /Q .\target
rmdir /S /Q .\node_modules
rmdir /S /Q .\frontend\generated
rm package.json
rm package-lock.json
rm pnpm-lock.yaml
rm pnpmfile.js
rm tsconfig.json
rm types.d.ts
rm webpack.config.js
rm webpack.generated.js
#echo off
echo project local vaadin-generated stuff removed.
:global_stuff
echo Step 3: Going to remove global stuff: removing pnpm stuff
pause
rem let user see what we do:
#echo on
rm -r -f %USERPROFILE%\.pnpm-debug.log
rm -r -f %USERPROFILE%\.pnpm-state.json
rmdir /S /Q %USERPROFILE%\.vaadin
rmdir /S /Q %USERPROFILE%\.pnpm-store
rem just in case - I encountered them here, too:
rmdir /S /Q D:\.pnpm-store
rmdir /S /Q U:\.pnpm-store
#echo off
echo global vaadin-installed stuff removed.
rem clear (and preload) default repository:
:repo_stuff
echo Step 4: Going to empty m2repository!
pause
rem let user see what we do:
#echo on
rem strange enough I again and again got "access denied" on certain .jars ||-( So we first take ownership...
takeown /R /F %USERPROFILE%\.m2\m2repository
rem ... before removing the stuff:
rm -r -f %USERPROFILE%\.m2\m2repository\*
cp -R %USERPROFILE%\.m2\repo-preload\* %USERPROFILE%\.m2\m2repository
#echo off
echo m2repository cleaned.
echo.
pause
I do this in multiple steps:
1st run: execute up to first pause - try to rebuild
if still not working:
2nd run: re-execute from top up to second pause - try to rebuild
if still not working:
3rd run: re-execute from top up to third pause - try to rebuild
At the latest after running the entire cmd-file the rebuilds so far always worked...

Answer 2

Deleting the node_modules folder worked for me most of the time.
