How to find out where sbt resolves dependencies from?

Question

I am using sbt 0.12 RC2.

My project has a bunch of library dependencies, and some of these trigger other dependencies. Some of these dependencies are unmanaged (in lib/), some are in my local .ivy2 repository, some are found in various remote repositories.

I'm looking for an sbt update-verbose or similar that will tell me exactly where sbt found each JAR file when it says:

[info] Resolving com.nicta#sbt-scoobi;0.0.1 ...
[info] Resolving org.scala-lang#scala-library;2.9.2 ...
[info] Resolving org.apache.opennlp#opennlp-maxent;3.0.1-incubating ...
[info] Resolving jwnl#jwnl;1.3.3 ...

sbtgenerates a very extensive report on how exactly the dependencies were resolved in target/resolution-cache/reports. Open one of the .xml files in a web browser, and you should see all the detail you need.

I'm not sure if this applies to sbt 0.12.x, but in 0.13.x, if you can find where your library lives in in the ~/.ivy/cache/... directory structure, the library's parent directory has a file named ivydata-x.y.z.properties which contains the URL where it found the dependency.

For example, if you cache for akka-streams looks like this:

.ivy2
└── cache
    └── com.typesafe.akka
        └── akka-stream_2.11
            ├── docs
            │   └── akka-stream_2.11-2.4.14-javadoc.jar
            ├── jars
            │   └── akka-stream_2.11-2.4.14.jar
            └── srcs
                └── akka-stream_2.11-2.4.14-sources.jar

you should find a file like this, containing download URL:

.ivy2
└── cache
    └── com.typesafe.akka
        └── akka-stream_2.11
            └──ivydata-2.4.14.properties

You can use show compile:dependency-classpath to show where the depedencies are

That doesn't give me what I'm looking for. It just lists the Java classpath. I'd like to know, e.g. for a dependency `com.nicta#sbt-scoobi;0.0.1`, where it actually came from (e.g. the unmanaged `lib/` directory, the local `~/.ivy2` repository, the local `~/.m2` repository, a specific remote Ivy2 or Maven repository, etc.). – Urban Vagabond Aug 05 '12 at 21:44
`Attributed(/Users/guillaume/.ivy2/cache/org.specs2/specs2_2.9.1/jars/specs2_2.9.1-1.11.jar)` so this one is from `~/.ivy2` – Guillaume Massé Aug 05 '12 at 23:34

No, that's the cache. That's not the source. It doesn't tell you whether it originated locally or remotely, or where from. – Urban Vagabond Aug 08 '12 at 13:52
