Urgent: production build failed

todo42 · June 19, 2025, 8:13am

Since two days and without any obvious reason, I am experiencing a serious issue with the production build of my 24.7.6 app.

I build via
mvn clean vaadin:clean-frontend package -Pproduction

The maven log mentioned, that a production mode bundle build is needed and create one.
I can remove src/main/bundles and it’s recreated.

After start via java -jar target/jarfile.jar the app starts and logs that it runs in production mode.
But the css definitions are missed, the login screen doesn’t have the background image and if I start a view/route with an @JsModule annotation, the following error:

ERROR c.v.flow.component.internal.UIInternals The component class XYZ.class contains ‘./copyToClipboard.js’, but this file was not included when the production package was created. The component is not working properly. Check whether you have a reference to the component and whether you are not just using it via reflection. If necessary, add @Uses(XYZView.class) where it is used.

I have read the existing forum posts

vaadin-component-not-work

What I have already tried:

set <optimizeBundle>false</optimizeBundle>
replace @JsModule(“./copyToClipboard.js”)
with @JavaScript(‘./copyToClipboard.js’)
add @Uses(XYZView.class) to MainLayout.java
add @LoadDependenciesOnStartup to the main application class

It’s an urgent problem for me because I have to provide an bugfix release for the productiion stage and can’t deliver …

Kind regards
Dominik

if I open the src/main/bundle/prod.bundle and take a look into config/flow-build-info.json the is the line

"productionMode": false

???

remove “vaadin:clean-frontend” from your CI build and ensure package.json and other frontend files are committed. Never had any problems

todo42 · June 19, 2025, 8:26am

removed (was only temporary in order to detect the reason) and both package*.json are already commited

The symptoms you describe are consistent with the typical cases where the the production bundle optimizer cannot detect that some part of the application is actually used. But those problems typically don’t pop out of of nowhere and they should also be fixed by any of the approaches that you mentioned that you’ve already tried.

The one thing that comes to mind is to try running the build with debug logging (i.e. the -X flag for the mvn command) to see if there’s anything there that looks suspicious.

After an (unsuccessfully) build, there is a file in src/main/bundles/prod/config/flow-build-info.json with "productionMode": false altough I use -Pproduction and also -Dvaadin.force.production.build=true, . I can manually modify this file (as long as I do not force new prod bundle of course) , set "productionMode": true, and rebuild for production. In this case, it seems to work.

But in case of a clean/new production mode bundle build, how this file is created ?
the troubleshooting docs mentioned

is located in the META-INF/VAADIN/config/ resource package.

But if I put a manually modified file there, it’s not taken by the build process. In this case, again "productionMode": false, and the app starts incorectly without css and images.

Is the build-frontend goal executed correctly?
The productionMode flag in flow-build-info is updated to true when the build-frontend goal is executed.
Also flow-build-info.json should not end up in the bundle.

Is the build-frontend goal executed correctly?

I attach the result fro mvn -X

The productionMode flag in flow-build-info is updated to true when the build-frontend goal is executed.

Nope, the file contains “productionMode”: false

Also flow-build-info.json should not end up in the bundle.

Nope, the prod.bundle contains this file.

The file getting into the bundle is wrong as the productioMode flag is updated after the bundle has been built AND it then contains local paths that shouldn’t be there at all.

marcoc_753 · June 19, 2025, 11:34am

If you check the JAR file you should find a META-INF/VAADIN/config/flow-build-info.json with the production flag on. That one should be the file processed by the frontend build, IIRC

mikhail.21 · June 26, 2025, 8:39am

I’ve given it a try to reproduce your problem with the Vaadin 24.7.6 starter, CopyToClipboard Vaadin recipe and @LoadDependenciesOnStartup. The false flag is indeed in the prod.bundle, but the JAR has it set to true.
Anyway, the app seems to start and work fine for me, at least the @JsModule scanned and work.
Do you have a chance to share a minimal reproducible example with us? (better to create a GitHub issue).

todo42 · June 26, 2025, 3:42pm

Thanks for your follow up, Mikhail. Unfortunatly its not really reproducible and I can’t share the whole project. But I collect the maven build run log from today and in case it failed again, than I can share this log file, at least.
