java.lang.IllegalArgumentException: transpose requires all collections have the same size

[opyate]

Hello,

I was wondering if someone could shed some light on a compilation
error I'm getting for which a Google search yields 2 unrelated
results:
1) https://issues.scala-lang.org/browse/SI-4786
2) a link to the lampsvn.epfl.ch source file where the exception text
can be found

The code to try can be found here:

https://github.com/opyate/scala-graph

To clone it, and the submodules:

git clone g...@github.com:opyate/scala-graph.git
cd scala-graph
git submodule init
git submodule update

For the usual target (2.9.1), the exception is:

java.lang.IllegalArgumentException: transpose requires all collections
have the same size

Also, trying it for 2.9.0-1:

java.lang.AssertionError: assertion failed

I've also tried building core's JAR first, putting the jar in
constrained/lib and then building constrained, and I get the same
error.

Thanks,
Juan

PS My co-developer reckons he can compile the whole lot in Eclipse.
I've asked for the project files to see if I'm missing something. In
that vein, could someone please point me to a good resource that
explains how the Eclipse incremental compiler works, how it differs
from how SBT uses the Scala compiler, etc. Running "last compile"
after getting the 2.9.1 error, in the stack trace I see
sbt.inc.IncrementalCompile and sbt.AggressiveCompile. How do these
work and how do they differ from the way Eclipse does things, for
instance?

[Jason Zaugg]

Please post the stack trace and the version of SBT that you're using.

Does it work after a 'clean'?

Thanks Jason.

I'm using SBT 0.10.1 and have also tried SBT 0.10.0, and I've tried
cleaning (and force-removing target directories).

Here's the pastie link, and the stack trace too:

Hi Juan,

Is -optimise enabled in Eclipse? If I remove -optimise, the project compiles.

How the incremental compilers work and how they differ are questions that would take some time to answer. There aren't any existing explanations that I know of.

Thanks for having a look, Mark.
I removed "-optimise" and "-Yinline" and it works.
