Re: [platform-ant-dev] AntHelper example and capturing output

[Kevin James <rincewind@xxxxxxxxxx>]

Thanks for your reply - I tried what you suggested, but I cannot quite
get it to work.

Firstly, the code in the AntHelper class (see
http://dev.eclipse.org/newslists/news.eclipse.platform/msg35076.html )
that I am modifying is as follows:

public ILaunch execute( IProgressMonitor monitor) throws CoreException {
	
	ILaunchManager launchManager =
DebugPlugin.getDefault().getLaunchManager();
	ILaunchConfigurationType type =
launchManager.getLaunchConfigurationType(IAntLaunchConfigurationConstants.ID_ANT_LAUNCH_CONFIGURATION_TYPE);
		
	String name =
launchManager.generateUniqueLaunchConfigurationNameFrom( antFile.getName());
	ILaunchConfigurationWorkingCopy workingCopy=type.newInstance(null,
name);
		
		workingCopy.setAttribute( IExternalToolConstants.ATTR_CAPTURE_OUTPUT,
true);
		workingCopy.setAttribute( IExternalToolConstants.ATTR_SHOW_CONSOLE,
true);

workingCopy.setAttribute( IAntLaunchConfigurationConstants.ATTR_ANT_PROPERTIES, userProperties);
	workingCopy.setAttribute( IExternalToolConstants.ATTR_TOOL_ARGUMENTS,
toolArguments );
		workingCopy.setAttribute( IExternalToolConstants.ATTR_LOCATION,
antFile.getAbsolutePath());

workingCopy.setAttribute( IExternalToolConstants.ATTR_WORKING_DIRECTORY,
workingDir.getAbsolutePath());
		workingCopy.setAttribute( IDebugUIConstants.ATTR_PRIVATE, true);
	workingCopy.setAttribute( IDebugUIConstants.ATTR_LAUNCH_IN_BACKGROUND,
false);
		
	return workingCopy.launch( "run", monitor);
}

where I have set the variable toolArguments to "-listener
net.kjames.AntBuildListener

AntBuildListener is the class I wrote to redirect messages to my
existing console, and it implements org.apache.tools.ant.BuildListener.

What I am seeing now is that in my runtime workbench the build is
running, I still get an Ant console named as the build file, but I get
no output in that window *or* my console window. I get no error messages
in my main workbench (I was expecting some kind of exception message if
there was a problem, such as classpath issues or something).

Do I need to add my plugin JAR to Ants' classpath somehow? I have seen
other posts on related topics about separate classloaders, but I go all
light-headed when people talk about classloaders :)

Cheers,
Kev.
