To answer my own question (with a little help from some - thanks!):
Create a file called archetype-metadata.xml in the
\src\main\resources\META-INF\maven directory, and put this into it:
<?xml version="1.0" encoding="UTF-8"?>
<archetype-descriptor name="basic-ear">
<fileSets>
<fileSet filtered="true" packaged="false">
<directory></directory>
<includes>
<include>**/*</include>
</includes>
</fileSet>
</fileSets>
<requiredProperties>
<requiredProperty key="projectName" />
</requiredProperties>
</archetype-descriptor>
That will process and generate what is needed.
Now, when you call the generate stage, you need to define the the property
"projectName" as a system property, by defining it as a system property:
mvn archetype:generate
-Darchetype.interactive=false
-DarchetypeCatalog=local
-DarchetypeGroupId=au.com.warpspeed.archetypes
-DarchetypeArtifactId=basic-ear
-DarchetypeVersion=1.0
-DgroupId=au.com.warpspeed.test
-DartifactId=SampleEAR
-Dversion=1.0-SNAPSHOT
-DprojectName=Sample
If you get an error similar to this:
[INFO]
------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO]
------------------------------------------------------------------------
[INFO] : org.apache.maven.archetype.exception.ArchetypeNotConfigured:
Archetype au.com.warpspeed.archetypes:build:1.0 is
not configured
Archetype au.com.warpspeed.archetypes:build:1.0 is not configured
Archetype au.com.warpspeed.archetypes:build:1.0 is not configured
It means that the property has not been specified. Hope this helps.
