Is there a way to turn on annotation processing globally? Currently I'm
having to do this on a project-by-project basis; I haven't been able to
find a place to change the setting so it takes effect for all projects.
(Ideally we'd like to have this turned on when a developer installs
Eclipse so they don't even have to think about it).
If that isn't possible, is there an API that I can call from my plugin
activator to turn on annotation processing for the project?
Thanks,
Mike

There is not; there are no globally configurable APT settings, only
per-project. It's a long story, but at core it has to do with performance
concerns for non-APT projects and some UI snafus that would have otherwise
been awkward to resolve.

Absolutely; indeed, what is normally done is that if a project is of a type
for which APT would be appropriate - for instance, a web services project -
the project creation wizard turns on APT at the same time that it constructs
the factory path.
The API you want is
org.eclipse.jdt.apt.core.util.AptConfig.setEnabled(IJavaProj ect jproj,
boolean enable). This turns APT on (or off) for the specified project.
Note that turning this setting on causes a change in the project, which will
ultimately trigger a build if autobuilding is turned on. This can be
awkward if you're planning on making a bunch of other changes as well. So,
you'd want to wrap that in a workspace job, or at least turn autobuilding
off for the duration of your configuration code.
