Build error in master

[telax1985]

Hello,

I'm attempting to build the complete project 'gs-spring-boot-docker-master/complete'.
Issuing the command mvn clean package docker:build results in the following:

[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException

No changes have been made to the project since downloading.
A previous error:

No plugin found for prefix 'docker' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo]
was resolved by adding the following to my maven settings.xml
<pluginGroups>
<pluginGroup>com.spotify</pluginGroup>
</pluginGroups>

I'm unable to make any further progress in resolving this error.

The issue was simple - the command is mvn clean package dockerfile:build and not mvn clean package docker:build
