Delete a file from a project generated through a custom maven archetype if a condition is met

With the help of Groovy, we can delete a file from a generated project if it meets a condition (for instance if a maven property equals a certain value).

Here is the procedure :
1) Create the archetype. To do that, type the following command from the root of a Maven project :
mvn archetype:create-from-project
result ==> [INFO] Archetype project created in E:\eclipse\workspace\celinio\target\generated-sources\archetype

The archetype project is here :

Copy-paste this folder structure into another folder in the workspace and import it as an existing maven project.
By default, I have decided that this archetype will generate a project which contains a file /src/main/resources/META-INF/configuration.xml. This is the file that I do not want to include if the maven property configurable is set to no.

2) Add the following required property to /celinioArchetype/src/main/resources/META-INF/maven/archetype-metadata.xml

    <requiredProperty key="configurable">

Also add this property to /celinioArchetype/src/test/resources/projects/basic/ :

3) Add the following groovy script archetype-post-generate.groovy under the folder /celinioArchetype/src/main/resources/META-INF/
It will be executed upon creating a project from this archetype.

* CF : This script will be executed upon creating a project from this archetype.
* It will delete a folder called configuration.xml if the value for the "configurable" property
* is set to true.

import java.nio.file.Files
import java.nio.file.Path
import java.nio.file.Paths

println "artifactId: " + artifactId
println "request: " + request
println "archetypeArtifactId: " + request.getArchetypeArtifactId()
println "archetypeGroupId: " + request.getArchetypeGroupId()
println "archetypeVersion: " + request.getArchetypeVersion()
println "archetypeName: " + request.getArchetypeName()
println "artifactId: " + request.getArtifactId()
println "groupId: " + request.getGroupId()
println "version: " + request.getVersion()

Path projectPath = Paths.get(request.outputDirectory, request.artifactId)
Properties properties =
String configurableProperty = properties.get("configurable")
println "configurableProperty : " + configurableProperty

if (!configurableProperty.equals("yes")) {
   println "Deleting the configuration.xml file"
   Path configPath = projectPath.resolve("src/main/resources/META-INF")   
   String configurationFile = "configuration.xml";    
   Path cxfConfigPath = configPath.resolve(configurationFile)
   println "cxfConfigPath " + cxfConfigPath  
   Files.deleteIfExists cxfConfigPath

To test it in eclipse, you will need to create a project from a run configuration as the groovy script is not executed if you go through the wizard (File > New Maven Project > select archetype etc)
See this link for details :

I have created a repository on github to host the code for this basic maven archetype :

I added two run configuration files which will help testing it.
