[FIXED] fabric8 maven plugin configuration with image running Java > 8

Issue

I am using fabric8 maven plugin to deploy a vertx application into Openshift. My application is running with Java 11.

However, by default, the fabric8 maven plugin uses a Java 8 Docker image to create my vertx application image.

How is it possible to configure fabric8 maven plugin to use a Java 11 image ? Does it provide other images for Java > 8 ?

Solution

I fixed it for my Spring Boot application by adding from configuration to the generator. For vert.x the solution could look like this:

<plugin>                                                     
    <groupId>io.fabric8</groupId>                            
    <artifactId>fabric8-maven-plugin</artifactId>            
    <version>3.5.42</version>                                
    <configuration>                                          
        <generator>                                          
            <config>                                         
                <vertx>                                      
                    <from>fabric8/s2i-java:3.0-java11</from> 
                </vertx>                                     
            </config>                                        
        </generator>                                         
    </configuration>                                         
</plugin>
