I'm creating a plugin to manage projects of a new type. I'd like to use my

nature is shown. I'm assuming that I don't have the nature properly
associated with the builder, but I can't tell what I've done wrong. I've
tried many variations (qualifing the builder reference in the nature with
the project id, or not qualifying it; using hasNature as true/false or
omitted altogether, and never get a builder).

Could someone point out my error?

I don't think the .project file is supposed to have a reference to the
builder. When Eclipse loads a project, it loads the project natures
specified in its .project file. The nature object is supposed to
override configure() and have it add its builder to the project if it's
not already there. I'm not sure where Eclipse stores the builder
information for projects -- probably somehwhere in .metadata.

George,

I have had the same kind of problem perhaps, its a good idea to look at

This is not a problem of the nature association with builder. You are
able to have many natures, associated with your project, but it doesn't
mean that each of them inevitably adds its own set of builders to the
project. Builder information should be stored in .project file. Use
IProjectDescription interface for example when you add your nature to
your project. This is a good moment to remove other builders (if they
were added to the project before) and to instantiate your own builder.

Here's the article on natures and builders:

http://www.eclipse.org/articles/index.html

Tip: Try looking at eclipse org articles for things. There are many good
articles there to answer questions.

Yup -- I've read the article.

I was adding the nature by putting it in the project description at the time
I created the project. It seems that if I do this, configure is never
called. Instead, I am now adding the BuildCommand directly in the project
creation wizard -- with that change, it gets added as a buildCommand.

I have nature that gets added later, after creation, and in the nature's
config() method I add the builder. In this case the nature's config
method is called, and so the nature adds the builder. The deconfig()
method removes the builder. This works.

Actually I think it may be a bug, but if you use the
IProject.create(projectDescription,...) with a nature already in the
description, it won't run the nature's config() method. It only runs the
nature's config method on IProject.setDescription on an existing
project. To me this is wrong because it doesn't give the nature a chance
to config things.

OK. I see and understand what you are saying in the article. It would be
good though if the javadoc for create itself says this because without
your explanation in the article it wasn't clear at all that (1) it
didn't call configure and (2) why it isn't smart to call configure for
create itself and (3) if you really want configure to be called when
creating a brand new project, to add the nature AFTER the create is done.

This is from the javadoc of IProject.create:

* If there is an existing project description file, it is not
overwritten. In either
* case, this method does not cause natures to be configured.

A year ago, which is the last time I needed to do this kind of stuff,
and the last time I looked at it, it didn't say that. :-) The additional
comment had been added since then.

However, it doesn't really stand out and can be easily missed in the
comment. And it wasn't clear why this was important to not configure
them. That would be nice to know.
