Describe about Maven Archetype

Maven Archetype is a Maven project templating toolkit that we can use to create our own custom template of the project (Think as a Image) , Then this image will be used to generate the project.

Component

  1. Archetype Descriptor = Configure selected file that we want to use for generate in archetype and define which folder is test folder or code folder. The location is in src/main/resources/META-INF/maven that consist of archetype.xml or archetype-metad.xml

Example: 

// Example
<fileSets>
    <fileSet filtered="true" packaged="true" encoding="UTF-8">
      <directory>src/main/java</directory>
      <includes>
        <include>**/*.java</include>
      </includes>
    </fileSet>
    <fileSet filtered="true" encoding="UTF-8">
      <directory>src/main/resources</directory>
      <includes>
        <include>**/*.properties</include>
      </includes>
    </fileSet>
    <fileSet filtered="true" packaged="true" encoding="UTF-8">
      <directory>src/test/java</directory>
      <includes>
        <include>**/*.java</include>
      </includes>
    </fileSet>
<fileSets>

  1. Prototype file = Store the code and configuration. The location is in src/main/resources/archetype-resources

  2. Pom for generate project = Pom for generated project from archetype. The location is in src/main/resources/archetype-resources

  3. Pom for archetype = It is root level of archetype project or target folder ( If archetype is created from existing project )

If you found some issue maybe you need to create the settings.xml in .m2 ref: https://stackoverflow.com/questions/59603307/calling-mvn-archetypecreate-from-project-on-a-simple-archetypewebapp-project-iarrow-up-right

  1. Verify correctness of code in target/generated-sources/archetype/src/main/resources/archetype-resources

  2. Navigate to folder target/generated-sources/archetype and run command mvn clean install

  3. Double check in .m2/repository whether the archetype is created or not.
