Scala compilation issue

[ppllaxxa]

Hello, maybe somebody had the same issue, or maybe there is som scala experts.

Once we updated library from "com.jcraft" % "jsch" % "0.1.55" to "com.github.mwiede" % "jsch" % "0.2.16" We are seeing strang compilation error:

scala.reflect.internal.FatalError:
bad constant pool index: 0 at 50924
while compiling: <some_our_class>
during phase: globalPhase=jvm, enteringPhase=namer
library version: version 2.12.6
compiler version: version 2.12.6
last tree to typer: Ident (_root_)

tree tpe: <root>
symbol: final package _root_
symbol definition: final package _root_ (a RootPackage)
symbol package: <none>
symbol owners: package _root_
call site: package sftp in package file in package file

== Source file context for tree position ==

5 import com.jcraft.jsch.Session;
6 import com.jcraft.jsch.SftpATTRS;
7 import com.jcraft.jsch.SftpException;
8 import com.jcraft.jsch.ChannelSftp;

SBT version 0.13.17 scala version 2.12.6 Java 8

Maybe somebody could advise what is the problem?

Hi @ppllaxxa,

I'm not very familiar with Scala, but some simple Google searches suggest this could be some sort of bug with the Scala compiler that is fixed if you upgrade to a newer version of SBT and/or Scala.

Thanks, Jeremy
