Notice that no tailwind configuration is added, and if I try to build the project the build will fail because npm cannot build the project.

I can provide more information if needed.

[wimdeblauwe]

Is there anything in the log file that ttcli generates?

@wimdeblauwe same error with the fresh 1.8.0 version when i select npm-base for live reload :

running on ubuntu 22.04 with Openjdk GraalVM CE 23.0.1

FYI if i choose Vite or devtools, ttcli works fine! This issue is only for npm-base live reload.

[wimdeblauwe]

That is weird. Can you try to manually run npm run build in the generated directory after the error happens to see if there is more output on what exactly might be the issue ?

[costalfy]

ok, this is the error after npm run build in the generated project :

$ npm run build

I try on another computer (archlinux) with node 22.14.0 and npm 11.1.0 without any error.

Maybe it's a NPM issue ??

[wimdeblauwe]

I really have no clue. I don't see any exception logged in the output when you run npm run build.

[vladdu]

I created https://github.com/wimdeblauwe/ttcli/pull/208 to print out the exception message from ExternalProcessRunner, so that it's easier to understand what was wrong.

In my case, I did not have mvn installed, I relied on the one embedded in IntelliJ.

[wimdeblauwe]

Is there anything I can do for this still? Can this be closed?
