which plugin is loaded

[Jeff Olson]

Is there anyway to ask sbt (0.13) which version of a plugin is loaded? I sometimes have projects that add plugins explicitly in project/plugins.sbt for which I have a different version specified in ~/.sbt/0.13/plugins/global.sbt. Now I realize that one or the other probably always takes precedence, but rather than having to remember which way 'round it is, I would like to just ask sbt. But I can't find a way to do this.

It would be nice if the 'about' cmd would tell me.

Global takes precedence. Also, you can change to the build definition project with `reload plugins` (and back with `reload return`). You can use the standard tools there. Without even doing a `reload`, you could look at project/target/resolution-cache/reports/ to see the usual Ivy resolution reports.

Here is a proposal that I think is reasonable to implement:

1. `about` accepts an argument "plugins".
2. The current plugins line is modified to:
a. be the same but with "see `about plugins`" for details
b. say "N plugins available, see `about plugins`" for details
c. some other variation
3. `about plugins` lists the ModuleIDs for plugins and the Plugin subclasses for each one

Thanks Mark,

Looking at libraryDependencies after 'reload plugins' shows me what I need to know for now. Your 'about plugins' proposal sounds great. That is exactly what I would like. I'm fine with any of the variants in point 2, although I think I like 2b best.

Please open an enhancement. A pull request implementing it is also welcome.

As it turns out, there's a nice plugin that implements pretty much exactly this:
