How to copy .gitignore file to the archetype JAR?

Question

I'm trying to include the .gitignore file to the jar. I tried everything but it still not copying the .gitignore file. Here is my resources and jar plugins

        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-resources-plugin</artifactId>
          <version>3.0.2</version>
          <configuration>
            <addDefaultExcludes>false</addDefaultExcludes>
          </configuration>
        </plugin>
        <plugin>
          <artifactId>maven-jar-plugin</artifactId>
          <version>2.4</version>
          <configuration>
            <includes>.gitignore</includes>
          </configuration>
        </plugin>

I even tried maven-resources-plugin with 3.1.0, but it's not adding? How to achieve it?

Archetype jars are created by the archetype plugin. So you have to configure that by setting the useDefaultExcludes to false:

        <plugin>
          <artifactId>maven-archetype-plugin</artifactId>
          <configuration>
            <useDefaultExcludes>false</useDefaultExcludes>
          </configuration>
        </plugin>

Note that the configuration key is called useDefaultExcludes as opposed to addDefaultExcludes for resources plugin.

I don't know why people are saying it doesn't make sense to add .gitignore to an archetype jar. I find it very useful to make sure target/ and the like are automatically ignored.
