Jetty server/servelet detected issue for Eclipse IDE set up

[laohixdxm2016]

While I set up Eclipse environment for OH2, I have the issue below.
Can expert shed some light?
Thank you very much.

Also, karaf-maven-plugin related errors were related.
I assume this is not critical and I can skip that.
Please correct me if I am wrong. Thank you.
