[cdt-dev] Running external tools with error parsing "org.eclipse.cdt.cor

[Achim Bursian <abu.aud@xxxxxxxxxxx>]

Hello everybody,
In my plugins I need to provide the ability to run several external 
tools on our C++ projects. They all analyze the code and return some 
information on stdout.

First, I added them all individually as CDT build configurations. That 
worked fine, the output showed in the console and could be analyzed by a 
CDT error parser (extension point="org.eclipse.cdt.core.ErrorParser") .
But it had a major disadvantage: The .cproject file grew huge, and the 
list of build configurations became quite cluttered. Logically these 
tools didn't belong there at all, these are no "builds", no new 
resources are generated.

So I added a new context menu for projects, from the actions I start the 
external tools like this (stripped down code):

       ILaunchManager manager = 
DebugPlugin.getDefault().getLaunchManager();
       ILaunchConfigurationType programType = manager
              
.getLaunchConfigurationType(IExternalToolConstants.ID_PROGRAM_LAUNCH_CONFIGURATION_TYPE);
       ILaunchConfiguration cfg;
       try {
           cfg = programType.newInstance(null, title);
           ILaunchConfigurationWorkingCopy wc = cfg.getWorkingCopy();
           wc.setAttribute(IExternalToolConstants.ATTR_LOCATION,
                   "${eclipse_home}/wrap/tool.cmd");
           wc.setAttribute(IExternalToolConstants.ATTR_WORKING_DIRECTORY,
                   workingdir);
           wc.setAttribute(IExternalToolConstants.ATTR_TOOL_ARGUMENTS, cmd
                   + " " + params);
           cfg = wc.doSave();
           cfg.launch(ILaunchManager.RUN_MODE, null, false, true);
           cfg.delete();
       } catch (CoreException e) {
         ...

This works, but I have no possibility to add an error parser, which is 
what I need.
Is there a "canonical" way of achieving what I want:
Launching an external tool with some parameters, and feeding the output 
both to a console view AND to a CDT error parser?
Any hints?
Thanks in advance
 Achim
