Production Mode not working in Vaadin24 with Java 21 and Spring boot 3

Mohit.8 · July 19, 2024, 12:24pm

Below is the build.gradle for the project

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.3.1'
    id 'io.spring.dependency-management' version '1.1.5'
    id 'com.vaadin' version '24.4.4'
    id "com.google.cloud.tools.jib" version "3.2.1"
}

group = 'de.test.ui'
version = '0.0.1-SNAPSHOT'

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(21)
    }
}

dependencyManagement {
    imports {
        mavenBom "com.vaadin:vaadin-bom:24.4.4"
    }
}

configurations {
    developmentOnly
    runtimeClasspath {
        extendsFrom developmentOnly
    }
}

repositories {
    mavenCentral()
    maven { setUrl("https://repo.spring.io/milestone") }
    maven { setUrl("https://maven.vaadin.com/vaadin-addons") }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-webflux'
    implementation 'org.springframework.boot:spring-boot-starter-data-elasticsearch'

    annotationProcessor 'org.projectlombok:lombok'

    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
}

tasks.named('test') {
    useJUnitPlatform()
}


vaadin {
    productionMode = true
}

I tried passing the gradle option also -Pvaadin.productionMode in the build command but still got the error.

No Gradle User myself. So you have to do the comparison yourself: here is a working example: base-starter-spring-gradle/build.gradle at v24 · vaadin/base-starter-spring-gradle · GitHub

Jean-Christophe.1 · July 19, 2024, 12:45pm

I’m also not a gradle user. But in the logs I can see this:
Build project in production mode instead, see https://vaadin.com/docs/latest/flow/production/overview

You need probably to run the build like this:
./gradlew clean build -Pvaadin.productionMode

Then run the application.

Mohit.8 · July 19, 2024, 1:03pm

Hey, thanks for this quick reply. But I have followed all the ways, including this gradle args.

Mohit.8 · July 19, 2024, 1:06pm

yeah, I have followed this also. Still the same issue.

marcoc_753 · July 19, 2024, 1:30pm

Also, make sure you do not have any JAR in classpath that contains the META-INF/VAADIN/config/flow-build-info.json file.
It could be, for example, an add-on adding that mistakenly did not exclude that file

Edit: only your main artifact should have the flow-build-info.json file.

Mohit.8 · July 19, 2024, 1:52pm

I can see it in two places with different values.

I’m not a Gradle user either, but I would say that the file in the first screenshot is the production version and in the expected folder.
However, I have no idea what the vaadin-generated folder is and if it gets into the final artifact or if it is available on classpath when you run the application.

EDIT: I checked on the starter project and I see the same vaadin-generated folder, so I suppose it is ok.

I can run the server in Production mode now after some changes, but with exactly the same properties on K8 still my deployment is failing with the same error!

How do you build the container image?

Mohit.8 · July 19, 2024, 4:10pm

I am using gradle jib plugin and using ‘gradle jib’ command to build all my spring boot app

Edit: Also using helm install for k8 deployment

If I do a production build with gradle clean build -Pvaadin.productionMode and then run gradle jibDockerBuild --image localhost:5001/my-test, I get a container image that executes the application in production mode.

If I do a gradle clean and then invoke jibDockerBuild it builds an image for an application running in development. This is expected because vaadinBuildFrontend has not been executed.

If I run ./gradlew vaadinBuildFrontend jibDockerBuild --image localhost:5001/my-test -Pvaadin.productionMode, again I get an image that runs the application in production mode.

Thanks @marcoc_753 for this detailed analysis, it was the culprit.
The jib task was not including the vaadinBuildFrontend in the execution I have added that manually and it worked like a charm.

Thanks
