JUnit with Ant returns "No runnable methods"

Question

I'm banging my head against a wall - I have a basically empty test file (its more to test my build file than anything else

A few months back my build file got corrupted - and for some reason starting a new project didnt fix it, so I had to make one from scratch, initially it just needed to support build, but now it requires test - and it is not working :(

package com.rcdc.questiondatabase;

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import static org.junit.Assert.*;
public class RCDCServiceTest {

  public RCDCServiceTest() {
  }

  @BeforeClass
  public static void setUpClass() {
  }

  @AfterClass
  public static void tearDownClass() {
  }

  @Before
  public void setUp() {
  }

  @After
  public void tearDown() {
  }

// TODO add test methods here.
  // The methods must be annotated with annotation @Test. For example:
  //
  @Test
  public void testHelloTest() {
    if(true){
      assertTrue(true);
    }
  }
}

My build file:

Answer 1

Your test classpath doesn't seem to have your test classes on it, so although Ant knows which test names it should look for to run, JUnit can't find the associated class to run.

From your follow-up comment - when Netbeans executes tests directly, it invokes it's own JUnit runner with associated listeners - or results parsers - that hook into the JUnit lifecycle so know what tests are doing. When you tell Netbeans to run an Ant task, it doesn't know about what Ant is doing (it doesn't have sight of the tasks within Ant), so doesn't know whether you're trying to run the JUnit task, or one of the many other tasks within Ant that it wouldn't make sense to try and reports on, other than in the console.
