Build fails -- Used to work

tim26 · January 4, 2021, 4:19pm

I have a project that worked perfectly, and built just fine. Haven’t touched it in about 8 months, and now after a minor bug-fix the project won’t compile.
The whole maven/build/webpack process is pretty obscure (and terrifying) to me so when it doesn’t just work I’m totally stuck.

Here is the error output form the stage that is failing. (If it matters I’m using intellij and this is from the vaadin-mavin-plugin)

Failed to execute goal com.vaadin:vaadin-maven-plugin:14.1.3:build-frontend (default-cli) on project gateway: Webpack process exited with non-zero exit code.
Stderr: ''

Any help would be greatly appreciated. Thanks.

Unfortunately, there was some issues in Vaadin 14.0 when the javascript bundle is building, perhaps 14.1 also.

In this link you have some explanation and some solutions: https://mvysny.github.io/Vaadin-troubleshooting/

If you still stuck, you can post your errors. Sometimes the error comes from a third party add-on, so you can also check the add-on you’re using.

In your case, it looks like this error:
Please perform the “Vaadin Dance” as mentioned above - it could be that the package-lock references an incompatible combination of package versions, or obsolete versions of tools such as Babel.

Solved.
Thanks so much for such a quick response.

I followed the guide you mentioned but none of the solutions there worked. But your comment that there were issues
in 14.0 & 14.1 led me to try upgrading to 14.4.5, and now the build works – great relief !
