Error retrieving required libraries

[Russ P.]

I am trying to set up for the Scala functional programming course that starts tomorrow. I downloaded the pre-packaged Scala IDE, and I tried to run the example assignment. When I tried to start sbt, I got had an error retrieving the required libraries. The error messages and a copy of the build file follow. I posted this on the coursera site for the course, but I have not received a reply yet, and I would really like to get this resolved ASAP so I know that I can take the course. Any help will certainly be appreciated. Thanks.

For the record, I currently have sbt 0.11.2 installed on the same machine, and it has worked fine for months.

For the record, I currently have sbt 0.11.2 installed on the same machine, and it has worked fine for months.

That transcript shows that the SBT 0.11.2 launcher (sbt-launch.jar) is being used. This launcher is not forwards compatible with 0.11.3+.

Type `which sbt` to see where it is coming from and adjust your PATH accordingly.

Or, better yet, remove your 0.11.2 installation and replace it with 0.12.0 (download from http://www.scala-sbt.org/download.html#manual). This version is backwards compatible with *all* previous SBT versions.

[Russ P.]

Thanks. I tried this:

> set sbt.version 0.12.0

but it didn't work? Is there a command to upgrade to 0.12.0? Or do I really need to delete the current one
and start over?

Sorry for the newbie-type questions, but the documentation for sbt seems to be scattered everywhere
and constantly changing. I hear it's a really good build tool, and I'm sure it is, but I wouldn't know a good build tool
from a bad one. I just want something that works.

[Arjan Blokzijl]

Yes, you really need to download the new one from here: http://typesafe.artifactoryonline.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/0.12.0/sbt-launch.jar

OK, thanks. New problem:

[error] (*:update) sbt.ResolveException: unresolved dependency: com.typesafe.sbteclipse#sbteclipse-plugin;2.0.0-M3: not found

What next?

[Russ P.]

Am I the only one getting this error, or is this a fundamental problem with the 0.12.0 sbt release? And if it is the latter, is anyone planning to correct it? Thanks.

Does this happen even with a freshly re-downloaded, freshly unzipped,
unaltered copy of the assignment project...?

I think I downloaded the one from Arjan's link earlier on this thread. Then I just unzipped and untarred it, pointed my path to it, and ran sbt.

Huh? Arjan posted a link to the sbt launcher. That isn't what I asked about — I asked about whether it happens with a freshly download, freshly unzipped copy *of the assignment project* — for the class.

Yes. That was the original problem that I posted about to start this thread.

I was looking forward to this online course, but getting things working is just taking too much time and causing too much frustration. For a course on functional programming, one would hope that the course software would at least function. I guess I'll just watch the lectures. So far, Martin seems to be an excellent lecturer.

Maybe I'll try again next time around the hope the bugs are worked out by then.

[Seth Tisue]

Russ,

The reason I ask if you're really certain that you're using a freshly
downloaded copy of the assignment files is as follows. The error
message you posted refers to
com.typesafe.sbteclipse#sbteclipse-plugin;2.0.0-M3, but the current
version of the assignment files doesn't use that version of the
plugin. It uses version 2.1.0. So that certainly makes it seem like
you may have an outdated copy of the assignment files — although who
knows, perhaps some other explanation is possible too.

Also, at https://class.coursera.org/progfun-2012-001/forum/thread?thread_id=103
one student reports: "The version could just be a distraction. I had a
problem with resolved dependencies fo scalastyle and sbteclipse caused
by running sbt in the "project" sub directory not the top directory
(ie where build.sbt is)." Could that be the problem you're having?

Perhaps you could post a complete transcript showing the entire
session in which you get the error, including the commands leading up
to it. For example, here's a complete transcript showing me
downloading the assignment files, unzipping them, and everything
working fine (well, except for a PermGen error that goes away when I
try again):

Hi! Took me a few seconds to put two and two together from your handle :-)

Knowing that you get the error even in an empty directory is helpful.

It appears to me that the key line in the transcript you sent is:
[info] Loading global plugins from C:\Users\Jeff\.sbt\plugins

Try moving the .sbt\plugins directory aside, or if that doesn't help,
the entire .sbt directory. Does that help?

(I don't use normally use Windows or Cygwin, or Eclipse or the
Typesafe Stack installer, so I don't know what might have put that
stuff there or if you might need it later in order to do Eclipse
stuff. Which is why I'm suggesting moving it aside instead of just
deleting it.)

Hope this helps,

[Jeff Axelrod]

The problem here was that there was an old sbteclipse sbt plugin installed.  To fix this, find your .sbt directory (on my Windows installation it's c:\Users\[name]\plugins.  Edit the build.sbt file and remove or comment out (//) the sbteclipse line.

I too am getting this issue and it certainly has nothing to do with the downloaded assignment.  Running the upgraded sbt by itself from the command line in an empty directory results in the Eclipse plugin error.  Complete shell dump follows:

Having experienced this before, I think sbt's handling of this situation could be improved, because it is confusing and seems rather fragile. Rather than just saying it can't find the plugin, maybe it could note that there's no matching version available in the repositories that's compatible with this version of sbt, and suggest disabling the plugin or trying a different version of the plugin?
