This server uses a remote git repository with SSH Authentication. The application.yml file is as follows:

security:
  provider:
    N=org.bouncycastle.jce.provider.BouncyCastleProvider:

I'm using IntelliJ Idea as my IDE and when I try to run the application from the IDE the server works. On the other hand, when I do mvn clean install and execute the .jar using java -jar ... I get the following error:

org.eclipse.jgit.api.errors.TransportException: [email protected]:Org-Engineering/config-repo.git: DefaultAuthFuture[ssh-connection]: Failed (NoSuchProviderException) to execute: JCE cannot authenticate the provider BC

To try and overcome this error I added security.provider.N property in my application.yml file and also added a static block with Security.addProvider(new BouncyCastleProvider()); in the main class. Nothing seems to work at this point.

Why am I able to run the application using the IDE and how can I make it work with the .jar. Any help or suggestion will be appreciated. Thanks in advance.

The problem was with the Java distribution I was using. It was fixed when I downloaded and replaced my JDK with OpenJDK distribution.
