Hi,

I tried to run example/run.sh start and I am getting the following traceback:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

Versions can be found below:

I am new to java, so it's hard for me to understand the exact issue. I would like to try out the tool. Let me know if you need any more information.

Thanks,

The stack trace says reactor.netty.ChannelBindException: Failed to bind on [0.0.0.0:8880] - this means another process is already using port 8880 on your machine. This error should go away by either killing the pre-existing process using port 8880 or by having diffy use a different port by modifying the run.sh script.

Please feel free to reopen the issue if you still have problems running the example.
