kie maven plugin, packaging kjar, test resources file not resolved

I understand the idiomatic way for a drools Kie rule Maven project to be built, as shown in the example, is to include in the pom:

• Kie Maven plugin
• set packaging to kjar

However, normally the file resources available under

src/
   test/
      resources/
         aresource.txt

should be available while running mvn test

However I noticed if packaging is set to kjar, this fails. It is working as expected if instead the packaging is set to the standard jar

Consider the following attached example project to replicate the issue. It contains the 'aresource.txt' file in the standard Maven layout directory src/test/resources as shown above. However the following simple test fails:

@Test
public void testFindTheFile() {
	URL resource = getClass().getResource("/aresource.txt");
	assertNotNull(resource);
}

Setting instead the project packaging to the standard jar instead, pass the test, and in fact it can be noticed the 'aresource.txt' file is available under target/test-classes directory.

Extract of the pom failing the test due to packaging set to kjar

<project ...>

  <groupId>com.acme</groupId>
  <artifactId>drools6test.testresources</artifactId>
  <version>0.0.1-SNAPSHOT</version>

Thank you in advance for your feedback accordingly;
