There is an issue I created for this problem: Long Class-Path may break the frontend · Issue #1571 · jmix-framework/jmix · GitHub

Also I created an issue in Vaadin, however the cause of problem is in Spring Framework, see:

  1. Long Class-Path may break the UI · Issue #16554 · vaadin/flow · GitHub
  2. PathMatchingResourcePatternResolver gives different results with classpath in JAR manifest · Issue #28276 · spring-projects/spring-framework · GitHub

Unfortunately, I still cannot find the workaround of the problem.

As “half” workaround you can try to define application property:

vaadin.productionMode=true

It allows you to start the application, however some components do not work correctly (at least DatePicker, DateTimePicker, TimePicker, DrawerToggle). Not sure the cause of problem for now. Probably need to create another issue.

Yes, as Jimmy said, Vaadin suggests the following work arounds Starting a Vaadin Project with Gradle | Starting a Project | Get Started | Vaadin Docs

  1. Using mavenLocal()
  2. Using vaadin.whitelisted-packages property
