Adding markers during project refresh [message #336577]

Hi everyone,

I have to create markers on resources, the thing is that I find the
resources to associate with markers during a project refresh which I think
locks the resource for modifications (I get a ResourceException : the
resource tree is locked for modifications).

So I'd like to know if there's a way to unlock the resource tree for
modifications or if there's any other way to add visual informations in
java editors.

Thanks,

Julien

Julien, are you trying to create markers inside IResourceChangeListener ?
Listeners are not allowed to modify resources during the notification
except during PRE_BUILD and POST_BUILD type of events.Instead, you could
try scheduling a Job from the listener to create the desired markers.

Thanks for your answer Hitesh.

The attempt to create markers is not inside an IResourceChangeListener but
is indirectly triggered by one.

I read the eclipse article about jobs
( http://www.eclipse.org/articles/Article-Concurrency/jobs-api .html) and
tried to create a job that waits 'till the resource allows modifications
but I get the following exception :
java.lang.NullPointerException
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:71)

I created a sub class of Job and put the following in the run method :

if( resource != null ){
IMarker m = null;
IResourceRuleFactory ruleFactory;
ruleFactory = ResourcesPlugin.getWorkspace().getRuleFactory();
ISchedulingRule rule = ruleFactory.createRule(resource);
IJobManager jobManager = Job.getJobManager();
try {
jobManager.beginRule(rule, monitor);
m = resource.createMarker(IMarker.PROBLEM);
m.setAttribute(IMarker.MESSAGE, "Test message");
} catch (CoreException e) {
e.printStackTrace();
}
finally{
jobManager.endRule(rule);
}
}

Any idea how I could get rid of the exception ?

Silly me I was just returning null (...) thanks for the tip !

Now I need to get the line number and position of IField, IMethod and
IType. I think it's possible is there any other than using the AST/DOM API
?

For declarations you can use the cheaper Java element API (see
org.eclipse.jdt.core.ISourceReference).
