Conclusions

In conclusion, we have covered the various steps to use JSch for sending and receiving files with an SSH/SFTP server.

We have set up a test using TestContainers to dynamically spin up a Docker image that served as our server for conducting our send/receive tests.

We used GraalVM and native compilation to improve the performance of our app.
