SSH error

[paxti]

Hi I have strange error, basically when CloudML tries to execute SSH command I am getting error

java.lang.NoClassDefFoundError: org/bouncycastle/openssl/PEMReade

and this class is missing from CloudML lib. Can you take a look, is linking is correct or it's something in my side.

Best regards, Iurii

Hi, I will have a look, which provider are you targeting (will help me finding the issue)? Best regards, Nicolas

So i am getting this error for the first time, so it's might be on my side, but i don't think so. Here is log:

When I am trying to register BouncyCastle manually

Security.addProvider(new BouncyCastleProvider());

I am getting same error just instead of "BouncyCastle not registered, using the default JCE provider" message is BouncyCastle is already registered, using the default JCE provider" after log is the same,

How are you using CloudML? (which jar?)

I am trying it right now and it seems to work properly, maybe you can try to force maven to update dependencies or to clean your .m2 repository,

Hi again, sorry for late response. I am still not sure what was wrong but I had to completely re-install Java to fit this issue. I am still getting warning

81164 [main] WARN net.schmizz.sshj.DefaultConfig - Disabling high-strength ciphers: cipher strengths apparently limited by JCE policy

but it works just fine. Thx again for your quick response.

Best regards, Iurii
