Oh, I noticed that this was merged to the main fork, so sorry for the noise.

Ismael,

Thanks for your response. Have you been using the fork? I'm not having
any luck getting the plugin enabled in sbt11 (following a combining
of the README's instructions and the SBT wiki).

(To clarify: it seems like that the fork only works with sbt-10. At
least, I can't get it working with sbt-11. I am probably going to put
this down for now but was just wondering what other people are doing.)

There are two plugins listed in the wiki. Have you tested both?

I only saw the one plugin at:

https://github.com/dvc94ch/sbt-scct

I guess a deeper problem is that I don't really understand SBT plugins
well-enough to debug when they're not working. The final line from the
previous link's instructions doesn't seem to work for me, and I've
(haphazardly) tried a bunch of the strategies (without luck) from:

https://github.com/harrah/xsbt/wiki/Plugins

While this might very well be PEBKAC it's a bit frustrating that this
was so much easier previously (in sbt7). That's why I was wondering if
anyone else is actually using scct or has set this up correctly with
sbt11.

Thanks,

There's also a jacoco plugin listed at
https://github.com/harrah/xsbt/wiki/sbt-0.10-plugins-list under code
coverage.

That's looking interesting but doesn't work on sub-projects yet. Scct doesn't either for that matter, it hangs on sub-projects in a loop looking for changes in system properties that aren't seemingly ever changed at that time.

(seems like a task ordering issue but I have not been able to spend enough time on it to tell).

You should take this to the SBT mailing list. It's a fairly active
group, and people usually get their problems solved there.

Thanks to everyone who responded and helped out.

Just to follow up on my original post, I did get the sbt-scct project
[1] working for me. The big thing I had missed was syncing up the
build.settings sbt version in both the sbt-scct project and my own
project. Even when one was 0.11.0 and one was 0.11.2 things didn't
work. I should have realized this but didn't.

I also hadn't realized that you could have both build.sbt and
project/Build.scala (which we had already been using for some custom
caliper code). Now that I look I do see SBT documentation pointing this
out, so this was just my own ignorance.

I hope to write up a document that explains how to do this from start
to finish with all the necessary steps included, and submit it as a
patch for sbt-scct.

Anyway, thanks again for everyone's help!

I was struggling with this same problem yesterday. Here's what I
finally did to get sbt to pick up my "coverage:" tasks:

#1> I did a git clone git@github.com:dvc94ch/sbt-scct.git into my
project directory
#2> I edited sbt-scct/project/build.properties to point to be:
sbt.version=0.11.2 and compiled using sbt 11.2
#3> I did a sbt publish-local in the sbt-scct project
#4> I edited my project/plugins.sbt and added:
addSbtPlugin("ch.craven" %% "scct-plugin" % "0.2")
#5> then I appendedmScctPlugin.scctSettings to my project's build
settings , i.e.

lazy val myProj = Project (
id = "myProj",
base = file ("."),
settings = buildSettings ++ ScctPlugin.scctSettings
)
