We use a project pom.xml which includes only some TestClasses like this one:

		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<testIncludes>
						<testInclude>test/persistence/jpatest/**/*.java</testInclude>
                                        </testIncludes>
				</configuration>
			</plugin>
		</plugins>

It works fine with eclipse and maven CLI, but Netbeans tries to compile all .java files inside test/ and does not respect the <testIncludes> tag from maven-compiler-plugin.
