Unsupported class version error
Hi,
I am trying to copy a zip file to a remote machine using the ant scp task.
The jar file required for this task jsch-0.1.43 is also put inside the ANT
lib folder. But i get the below exception while this target gets triggered
BUILD FAILED

Chris-
sounds like a VerifyError which is wrong class e.g. 1.4!=1.5
get the sources and recompile and rejar

I have exactly the same problem that Lis has described
Ant: version 1.8.1 compiled on April 30 2010
JRE: java version "1.6.0_21"
Jcraft jsch: jsch-0.1.43.jar
The only fix for me was to downgrade to jsch-0.1.40.jar
Did you find a solution @Lis?

What java-version are you running ant with? It looks like the jsch-lib is
compiled with a higher versionnr than you support?
