Exception when trying to use Ammonite REPL about ammonite

[lihaoyi]

Hmm try scala 2.11.4 or Java 8? Those are the things that come to mind

[jchayat]

Yes, It works on 2.11.4

Does it work on 2.10.4? I had a resolution problem.

[lihaoyi]

Doesn't work with 2.10.4

[lihaoyi]

Maybe at some point I'll cross publish; for now 2.11.4 it is ^_^

[jarandaf]

I also experience this issue, scala version is 2.11.4 and java version is 1.8.0_25.

[lihaoyi]

@jchayat @jarandaf The latest version is cross-published, the older ones don't. Have you tried that?

[alexarchambault]

@jarandaf @lihaoyi Binary incompatibilities in the scala-compiler JAR are quite common, I ran into one between 2.10.4/2.10.5 (macro related methods that changed), there are also some in 2.11 (2.11.2 vs 2.11.4 or 5 for sure, ran into it with the spark repl jar). Using the exact same version as ammonite should be recommended.

[lihaoyi]

@alexarchambault should we cross-publish Ammonite against different minor versions of Scala? How does one even do that? Presumably it's possible

[alexarchambault]

@lihaoyi shapeless is doing it with scala 2.10 (see https://github.com/milessabin/shapeless#shapeless-210), but it's cumbersome for its users. I'm really shared about this (I'll let you decide anyway!) You could just recommend to use the latest scala version.

[alexarchambault]

To go the cross publishing route, it should just be a matter of adding

crossVersion := CrossVersion.full

crossScalaVersions := (0 to 5).filterNot(3.==).map("2.11." + _) ++ ...

in build.sbt, and for the users, use

"com.lihaoyi" %% "ammonite-..." % "..." cross CrossVersion.full

as a dependency instead of just

"com.lihaoyi" %% "ammonite-..." % "..."

(after-thought: not that cumbersome)

[jarandaf]

Using same scala version as Ammonite seems to solve the problem (or at least, the REPL starts). I am facing another problem now (see #35), probably not directly related.

[lihaoyi]

Fixed in 0.2.8
