[cdt-dev] ConcurrentModification Exception
|
Hi,
In my plugin I am trying to determine if a project is a makefile project
(if it is, I do some special processing). I am doing this during my
plugins earlyStartup() method. When doing this, I am occasionally
getting a ConcurrentModificationException. See trace below:
I have tried 2 different methods to detect a makefile project, but both
result in the same problem.
Method 1:
ICProjectDescription projectDesc =
CoreModel.getDefault().getProjectDescription(project, false);
if (projectDesc == null)
return false;
IConfiguration cfg = ManagedBuildManager.
getConfigurationForDescription(projectDesc
.getDefaultSettingConfiguration());
if (cfg == null)
return false;
return (!cfg.getBuilder().isManagedBuildOn());
Method 2:
private static boolean isProjectType(IProject project, String type) {
IManagedBuildInfo info = ManagedBuildManager.getBuildInfo(project);
if (info != null) {
IManagedProject managedProject = info.getManagedProject();
if (managedProject != null) {
IProjectType projectType = managedProject.getProjectType();
IBuildPropertyValue property = null;
if (projectType != null) {
property = projectType.getBuildArtefactType();
if (property != null) {
String artifactName = property.getId();
if (type != null)
return type.equals(artifactName);
}
} else {
if (type == null)
return true;
}
}
}
return false;
}
Is there a way I can do this without getting the Exception?
