How to permanently disable javadsl namespace when coding with Akka Streams

Question

I have started to learn Akka Streams. One of my very very big annoyances of the product is that almost all classes appear in both javadsl and scaladsl namespaces.

Somehow, IntelliJ will automatically import classes from javadsl namespace first. This leads to syntax errors and a lot of wasted time. Problems disappear when I import the same class from the scaladsl namespace.

How can I block/hide the javadsl namespace permanently? perhaps there is some setting in SBT so that when I import the akka streams dependency, I tell SBT to kill the visibility to the javadsl namespace.

Or maybe some other solution which prevents IntelliJ from automatically importing classes from javadsl namespace.

Answer 1

You can do in IntelliJ IDEA:

Just add akka.stream.javadsl there, and it should stop suggesting items from the javadsl package.
