Eclipse removes my resource filters [message #1444939]

My goal was to create a project in Eclipse that has only certain directories and files. I figured I can do it by setting filters on each folder. So I generated a .project file with the following filters:

Everything worked fine when I opened the project and refreshed the resource tree. However, when I exited Eclipse, my .project had only the top-level filters and few sub-folders. Where is the catch? Why Eclipse removed the rest?

I think I figured it out. Eclipse has problems with such long ids, though itself it creates them that long.

No, I was wrong. Eclipse still sometimes removes filters regardless of id lengths. Eclipse is an infinite source of really joyful frustration.

So is there any idea why Eclipse removes resource filters?

If you create a filter the normal way (ie, via the UI that Eclipse provides), do they stick or are they, too, mysteriously removed? I suspect there is something subtle about the way you're trying to insert filters that's not kosher. Realize that you're mucking around in Eclipse's own internal state management behind its back, so it had better be *exactly* correct.

It doesn't remove them all, it leaves some, so I guess to check your theory I would have to manually add the amount of filters that surpass this threshold. It's quite an arduous task. Maybe I'll try on weekend. Or, I actually can try to add a filter manually and check what other files Eclipse changes besides .project. This is a thing I don't like about Eclipse: settings are randomly mashed among furiously random files.

Why it is behind its back? Can I, for example, edit .project file manually?

Yes, but...

a) don't do it while Eclipse has the project open because your changes
won't stick, and

b) you had better know what you're doing in there or you'll break the
project.

I don't do it.

That's why I'm asking questions in this forum.

This really isn't a "newcomer" type of question. I'm moving it to the JDT forum where it might get the right person to notice it.

Eric, are you sure moving this topic to this forum was right? So far there is no reaction from the community.

Sadly the JDT committers don't seem to be very active on this forum. You could try writing to one of the JDT dev mailing lists, either jdt-dev or jdt-core-dev. See https://projects.eclipse.org/projects/eclipse.jdt/contact
