Java Programming

Hi all,

this is my first post here, so i dont know if it's the right place (sorry if so).

I try to run an ant target within a java program.
My build file (test.xml) is:

<project name="test" default="usage" basedir=".">
  <target name="test1" >
    <echo message="Target test1" />
    <antcall target="test2"/>
  </target>
  <target name="test2" >
    <echo message="Target test2" />
  </target>
</project>

My java programm is:

public static void main (String [] a) {
  String buildFileName = "test.xml";
  File buildFile = new File (".",buildFileName);
  Project project = new Project();
  project.init();
  ProjectHelper helper = new ProjectHelperImpl();
  helper.parse(project, buildFile);
  project.executeTarget("test1");	
}

This causes following exception:

Exception in thread "main" test.xml:4: The following error occurred while executing this line:

If I use

<ant antfile="test.xml" target="test2"/>

instead it works perfecly. But I don't want to. The target "antcall" was created to call targets within the same build-file, but why build.xml is referenced anywhere?

Might this be an ant bug?
Any ideas?
