Using JSCH version 0.2.24 without Proguard runs normally. Does anyone have a solution for this? I am currently using 0.1.55 again.

Thank you GGK

I fell into the trap. it was not due to proguard, but to the crypto module, which is required in 0.2.24. I added jdk.crypto.ec to the JAVA binary and that was it.

Thank you
