I wanted to build my backend + frontend using Vaadin 24.0.0 with spring boot 3.0 Unfortunately below exception occurs during exeuction of bootJar gradle task. I do not know how to fix this :(
Executing gradle task 'bootJar' produces this error:
* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':vaadinBuildFrontend'.

How to fix this ? cant build production ready app :(
I am not sure if this is the answer. My Question was asked when vaadin version was 24.0.0
Now it is: 24.1.4
Spring boot: 3.1.2
Java: 17
Kotlin: 1.9.0
After doing many changes like swapping javax to jakarta imports everything seems to work fine with these settings:
applications.properties for production mode:
vaadin.productionMode=true
vaadin.servlet.productionMode=true
vaadin.frontend.hotdeploy=false
vaadin.compatibilityMode=false
applications.properties for developer mode:
vaadin.productionMode=false
vaadin.servlet.productionMode=false
vaadin.frontend.hotdeploy=true
vaadin.compatibilityMode=false
plugins in build.gradle:
plugins {
id "java"
id "application"
id "org.springframework.boot" version "3.1.2"
id "io.spring.dependency-management" version '1.1.2'
id "com.vaadin" version "24.1.4"
id("org.jetbrains.kotlin.jvm") version "1.9.0"
id("org.jetbrains.kotlin.kapt") version "1.9.0"
id("org.jetbrains.kotlin.plugin.allopen") version "1.9.0"
id "org.jetbrains.kotlin.plugin.jpa" version "1.9.0"
}
apply plugin: 'kotlin'
Let me know if this is the real fix. Works for me. Vaadin 24 had some issue which they dont want to tell us about.
