Hello, I am trying to call the exec task from the api.
I get this nullPointerExecption
java.lang.NullPointerException

Exception in thread "main"
This is my code:
final class Myexec extends ExecTask
{
public Myexec()
{
Project proj = new Project();
proj.init();
taskType = "exec";
taskName = "exec";
Target target = new Target();
}
}
Myexec exec = new Myexec();
exec.init();
exec.setExecutable(tool.getProgname());
File dir = new File(tool.getLocation());
exec.setDir(dir);
exec.setVMLauncher(false);
//exec.setOutput(err.getErrorOutputFile());
try
{
exec.execute();
}
catch (BuildException buildex)
{
err.output(this.getClass(),"Error. "+buildex.getMessage(),2);
}
Can someone tell me what I am doing wrong?
Thanks,
Oliver
