I can't use the plugin exclusively on a child module

[jacklaplante]

Description

I want to use this docker-maven-plugin exclusively on one child module of my maven project.

How to reproduce

I tried putting the plugin only inside the pom of the child module. When I did mvn clean package docker:build it failed:

[ERROR] No plugin found for prefix 'docker' in the current project and in the plugin groups

If I put the plugin anywhere inside the parent pom (in <plugins> or pluginManagement) then it assumes that I'm making a docker container from the parent module and every child module.

What do you expect

I only want one container from one child module.

Software:

• docker version: 1.11.2
• docker-maven-plugin version: 0.4.11
• maven version: 3.3.9

I believe you can tackle this in one of two ways

1. you can configure the plugin in the parent pom's <plugins> section but default the plugin configuration to skip the docker build, and override that in the child module to not skip
2. configure it only in the child module and bind the build goal to the package phase.

I'm trying to get the docker build to skip by default by adding <skip>true</skip> to <configuration> but that isn't working. Is there a different way to do it?

[mattnworb]

The configuration property is named skipDockerBuild, not skip.

Thanks for the help! It's very much appreciated.

I am trying this approach: configure it only in the child module and bind the build goal to the package phase

But still getting the same error.

Here is the snippet of how the plugin is sourced in the child module: `

        <plugin>
            <groupId>com.spotify</groupId>
            <artifactId>docker-maven-plugin</artifactId>
            <version>0.4.11</version>
            <configuration>
                <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                <dockerDirectory>.</dockerDirectory>
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
            </configuration>
            <executions>
                <execution>
                    <id>docker-build</id>
                    <phase>package</phase>
                    <goals>
                        <goal>build</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

`

Please can you review ?

Any clear help on this on how to effectively build the docker image for a multi-module app?
