      public class JUnitLauncherTask
      extends Task

  An Ant `Task` responsible for launching the JUnit platform for running tests. This requires a minimum of JUnit 5, since that's the version in which the JUnit platform launcher APIs were introduced.

  This task in itself doesn't run the JUnit tests, instead the sole responsibility of this task is to setup the JUnit platform launcher, build requests, launch those requests and then parse the result of the execution to present in a way that's been configured on this Ant task.

  Furthermore, this task allows users control over which classes to select for passing on to the JUnit 5 platform for test execution. It however, is solely the JUnit 5 platform, backed by test engines that decide and execute the tests.

  See Also:
    JUnit 5 documentation for more details on how JUnit manages the platform and the test engines.

    - #### execute

          public void execute()
                       throws BuildException

      Description copied from class: `Task`
      Called by the project to let the task do its work. This method may be called more than once, if the task is invoked more than once. For example, if target1 and target2 both depend on target3, then running "ant target1 target2" will run all tasks in target3 twice.
      Overrides:
        `execute` in class `Task`
      Throws:
        `BuildException` - if something goes wrong with the build.

    - #### addConfiguredClassPath

          public void addConfiguredClassPath​(Path path)

      Adds the `Path` to the classpath which will be used for execution of the tests
      Parameters:
        `path` - The classpath

    - #### addConfiguredTest

          public void addConfiguredTest​(SingleTestClass test)

      Adds a `SingleTestClass` that will be passed on to the underlying JUnit platform for possible execution of the test
      Parameters:
        `test` - The test

    - #### addConfiguredTestClasses

          public void addConfiguredTestClasses​(TestClasses testClasses)

      Adds `TestClasses` that will be passed on to the underlying JUnit platform for possible execution of the tests
      Parameters:
        `testClasses` - The test classes

    - #### addConfiguredListener

          public void addConfiguredListener​(ListenerDefinition listener)

      Adds a `listener` which will be enrolled for listening to test execution events
      Parameters:
        `listener` - The listener

    - #### setHaltonfailure

          public void setHaltonfailure​(boolean haltonfailure)

    - #### setFailureProperty

          public void setFailureProperty​(java.lang.String failureProperty)

    - #### setPrintSummary

          public void setPrintSummary​(boolean printSummary)
