Hi everyone, I am checking the source code and trying to figure out where did you get the directories to read task files like .epf. If I don't make any mistake, do you get the directories from the class "
FileTaskProvider"?? Thank you for answering my question:)

I think you're looking for the PreferenceFileTaskScanner.

If you use a debugger it will help you answer some of these questions.

If I don't misunderstand the code, PreferenceFileTaskScanner is to get all the *.epf file under a certain directory, right? I meant there must be something pass the directory to PreferenceFileTaskScanner, right?

What does the code say?

The comments of the class PreferenceFileTaskScanner said: 

 * Provides support for treating Elipse "epf" files as first class

 * {@link Task}s. Each EPF file can have a recommended header section

 * consisting of comments with javadoc like tags specifying information

 * about the task to be performed for this file.

I have checked the methods of the PreferenceFileTaskScanner, I think it gets the directory by using methods from another class. And there is not comments for class FileTaskProvider. That is why I post the question :)

The code says:

protected void scan(IResourceTaskProvider source, TaskCollector collector) {
    /**
     * Scan our source. Add a new Task for each EPF found.
     */
    for (IResourceTaskReference taskRef : source.getTaskReferences(".epf")) {
  So, the epf files are listed in the IResourceTaskProvider. Look for something that implements that interface, and go from there.

Jingjie, I hope you are successful, but I'm just too busy to spend a lot of time on the Workspace Mechanic code base, particularly for questions that can be answered by reading the code. I suggest you spend some time learning how to navigate a small Java code base, and save your questions for more sophisticated ones.

Hi Roberta,

Thanks very much for your time.I did exactly the same thing, and I found FileTaskProvider. I am a Java and Eclipse plug-in dev beginner, I didn't quite understand the code of FileTaskProvider ,so I posted the question to make sure. Again, really appreciate your time :)
