In PlayN, how do you exclude a directory from being compiled by Maven?

Question

I want to build the html version of my game from the command line using maven. However, when I run the package command for the core folder:

mvn clean package -pl core,html

I get the following errors because of some unit tests in my source path:

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] /home/klenwell/projects/mygame/playn/mygame/core/src/main/java/mygame/playn/tests/unit/UserDataTest.java:[3,23] package org.junit does not exist

[ERROR] /home/klenwell/projects/mygame/playn/mygame/core/src/main/java/mygame/playn/tests/unit/UserDataTest.java:[7,16] package org.junit does not exist

...

How can I exclude the directory with these test files from being included in the compilation?

Answer 1

Adding the following block to the plugins section of my core pom.xml file excluded tests from compilation and allowed the build to succeed:

  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <excludes>
        <exclude>**/*Test*.java</exclude>
      </excludes>
    </configuration>
  </plugin>
