maven archetype property substitution

Question

Anybody knows is it possible to make substitution for default value of one requredProperty to another in archetype-metadata.xml ?

So, I try to do something like this:

<requiredProperty key="name"/>
<requiredProperty key="groupId">
   <defaultValue>com.mycompamy.${name}</defaultValue>
</requiredProperty>

But when I start to generate project from artifact in interactive mode, maven asks me about groupId property first. But not for name as I expected.

Is it possible to change this behaviour?

Answer 1

Your problem is caused by required property loading order. Maven loads every custom required property in alphabetical order. You probably cant change it. But there are 2 ways which will solve your problem:

1. Renaming ur variables like this:

   "0_name"

   "1_groupId"

   Now it will ask you about name firstly.

2. Use full maven command, passing only name parameter

   mvn archetype:generate -DarchetypeGroupId=?? -DarchetypeArtifactId=?? -DgroupId=?? -DartifactId=?? -Dversion=?? -Dpackage=?? -Dname=??

   Replace ?? with valid parameters

Hope it will helps you.
