skip certain modules during deploy in multi-module maven java project on appengine w/ appengine-maven-plugin

Question

I have a multi-module maven java project. In the parent pom:

<modules>
    <module>core</module>
    <module>batch-worker</module>
    <module>be</module>
    <module>scheduler</module>
    <module>migrations</module>
</modules>

Both the migrations and core modules aren't services I wish to deploy but just common packages used throughout all services.

When i attempt a deploy with mvn appengine:deploy, I receive goal execution failures because the core and migrations modules do not define an app.yaml as they are not deployable services.

How do I skip these and omit them from the deploy?

Answer 1

You can define your services in the maven plugin.

<plugin>
    <groupId>com.google.cloud.tools</groupId>
    <artifactId>appengine-maven-plugin</artifactId>
    <version>2.2.0</version>
    <configuration>
      <services>
        <!-- Default service-->
        <service>${project.build.directory}/${project.name}-${project.version}</service>
        <!-- other service-->
        <service>${project.parent.basedir}/other_module/target/other_module_finalName-${project.version}</service>
      </services>
    </configuration>
</plugin>

However, in the documentation the services are take into account only for start/stop command and not for deploy. I don't know if it works.

Let me know.
