Building Production version fails, building for development works fine

General
1

Dev build works: mvnw clean package -Pdevelopment

Prod build fails: mvnw clean package -Pproduction -X

It’s a 100% Flow app, no Hilla

A bit of POM:

    <properties>
        <java.version>21</java.version>
        <vaadin.version>24.8.5</vaadin.version>
    </properties>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.5.3</version>
    </parent>
...

 <plugin>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-maven-plugin</artifactId>
    <version>24.7.6</version>
    <executions>
        <execution>
            <id>frontend</id>
            <phase>compile</phase>
            <goals>
                <goal>prepare-frontend</goal>
                <goal>build-frontend</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Vaadin version and Maven Plugin MUST be in sync

Makes sense, I just removed the plugin from the POM, since there is no version 24.8.5

What? Removed? Without the plugin, you can’t build production mode :sweat_smile:

The version 24.8.5 should be available Maven Central: com.vaadin:vaadin-maven-plugin

You are right, I couldn’t get it loaded inside IntelliJ, so I just tested the difference and it compiled, but it will not run of course.

I’m not really sure why, but I cleaned a lot of stuff and now it compiles in production mode too.

Thanx
