Re: [cdt-dev] modify build variables

[James Blackburn <jamesblackburn@xxxxxxxxx>]

Take a look at IEnvironmentVariableManagerTests in
org.eclipse.cdt.core.tests plugin.

The environment is per configuration. So you could do something like this:

		prjDesc = CoreModel.getDefault().getProjectDescription(project);
		ICConfigurationDescription[] descs = prjDesc.getConfigurations();

		IEnvironmentVariableManager envManager =
CCorePlugin.getDefault().getBuildEnvironmentManager();
		IContributedEnvironment contribEnv = envManager.getContributedEnvironment();

		// Try setting an environment variable
		final IEnvironmentVariable var = new EnvironmentVariable("FOO", "BAR");
		contribEnv.addVariable(var, prjDesc.getConfigurationById(id1));

		// Get an environment variable:
		IEnvironmentVariable var2 = envManager.getVariable(var.getName(),
prjDesc.getConfigurationById(id1), true);

                // Save the changes to the environment
		CoreModel.getDefault().setProjectDescription(project, prjDesc);


Cheers,
James
