Vaadin 23 issue with production mode using spring boot with gradle task bootJar

Question

I'm trying to create an executable jar file. For this project I am using gradle. I am building executable jar file using gradle task "bootJar". Unfortunately after starting my jar file like this: java -jar -Dvaadin.productionMode=true /Users/fluento/IdeaProjects/respinewsbackend/build/libs/respinews.jar

or:

java -jar /Users/fluento/IdeaProjects/respinewsbackend/build/libs/respinews.jar

this error occurs in console:

Caused by: java.lang.IllegalStateException: Running project in development mode with no access to folder '/home/fluento/StudioProjects/respinewsbackend'. Build project in production mode instead, see https://vaadin.com/docs/latest/flow/production/overview

As stated below I have 'spring.profiles.active=prod' in my application.properties.file.

Please tell me what is wrong here. 😭 Running from IntelliJ Idea in development mode works fine.

Error from console:

Answer 1

As @Knoobie pointed out, you don't simply "turn on" production mode for Vaadin. You need to build the jar with the production profile instead, and then, executing it in the same way you have been doing, should work fine.

Adding the productionMode to your .gradle file should do the trick, as explained here.

vaadin {
    pnpmEnable = true
    productionMode = true
    generateBundle(true)
    optimizeBundle(true)
    vaadinPrepareFrontend
    vaadinBuildFrontend
}

Answer 2

The production profile to build your application isn't read from your active spring boot profile. Please follow the official guide to get up and running: https://vaadin.com/docs/latest/flow/guide/start/gradle/#production

Enabling Vaadin production mode through build.gradle:

vaadin {
   productionMode = true
}
