java.security.NoSuchAlgorithmException with maven and bouncycastle

Question

I'm unable to start the jar if I create it via maven, debugging works just fine. I have done the decryption: RSA/NONE/OAEPPadding (I am using bouncycastle) and although I register bouncy caste, java doesn't notice it.This doesn't happen if I debug it in intellij. The console output is the following:

adding BouncyCastleProvider2
java.security.NoSuchAlgorithmException: Cannot find any provider supporting RSA/NONE/OAEPPadding

    at java.lang.Thread.run(Thread.java:745)

and the Java code:

System.out.println("adding BouncyCastleProvider2");
        try {
            Security.addProvider(new BouncyCastleProvider());
        } catch (Error e) {
            e.printStackTrace();
        }
        try{
            // La clef RSA
            PEMReader pemReader = new PEMReader(new StringReader(key));
            KeyPair pObj = (KeyPair) pemReader.readObject(); 

            // Encrypt
            Cipher cipher = Cipher.getInstance("RSA/NONE/OAEPPadding"); 
            cipher.init(Cipher.DECRYPT_MODE, pObj.getPrivate());
            return cipher.doFinal(array);

        }catch(Exception e){
            e.printStackTrace();
        }

(I am catching the error out of desperation, was hoping for a noclassdef)

here is my maven-assembly-plug-in (the only other plug-in is the compiler plugin):
