Remote connect using SSHJ in a Maven shade jar

Question

I have used SSHJ to connect to a remote machine and that works fine when doing it from IntelliJIDEA. However when I try to build an "uberjar" using maven-shade-plugin I get the stacktrace shown below.

I do have org.bouncycastle.bcprov-jdk16 in the shade jar, and my program explicitly adds that as a provider: Security.addProvider(new BouncyCastleProvider());

I have tried to sign the jar according to the answer provided here: SSHJ and the Maven shade plugin Testing with 'maven-jarsigner-plugin' and 'maven-gpg-plugin' but with no luck.

Any help is much appreciated! Thanks!

Answer 1

I finally gave up on trying to put everything in a big "uberjar".

Instead I assembled all the jars using maven-assembly-plugin, and then extract and add them to the classpath in order to execute, e.g. 'java -cp all-needed-libs/* com.company.MainClass'.
