Maven avoid certain files from being copied to test-classes

Question

I'm trying to avoid that certain file types don't end copied in target/test-classes. The code I have right now in my pom file but it's not working is:

<plugin>
 <groupId>org.apache.maven.plugins</groupId>        
  <artifactId>maven-resources-plugin</artifactId>
   <executions>
    <execution>
     <id>default-testResources</id>
      <phase>process-resources</phase>
       <goals>
        <goal>testResources</goal>
       </goals>
       <configuration>                       
        <outputDirectory>
         ${project.build.directory}/test-classes
        </outputDirectory>
        <testResources>
         <testResource>
          <directory>src/test/resources</directory>
          <filtering>true</filtering>                                   
          <excludes>
           <exclude>**/*.nc</exclude>
          </excludes>
        </testResource>
       </testResources>
      </configuration>
     </execution>               
    </executions>
  </plugin>

Answer 1

I was finally able to do what I wanted with:

<execution>
 <id>default-testResources</id>
 <phase>test-compile</phase>
 <goals>
  <goal>testResources</goal>
 </goals>
 <configuration>
  <resources>
   <resource>
    <directory>${project.basedir}/src/test/resources </directory>
    <excludes>
     <exclude>**/*.nc</exclude>
    </excludes>
   </resource>
  </resources>
 </configuration>
</execution>

With this code, which is very similar to the one I posted in the question, and by changing the maven version in my eclipse settings from 3.3.3 to 3.3.9 I'm able to avoid the files that I wanted to be copied to target/test-classes
