Scala IDE support is bad? What IDE are you using? I find IDE support in IDEA almost on par with that of Java. It is very fast, has accurate error highlighting, very good smart autocomplete, understands advanced Scala features, supports most refactoring I care of, but most importantly works reliably.

I've used IntelliJ for Scala some time and did encounter way more IDE bugs than in Java. I think JetBrains did a good job, but Scala is not engineered towards tool support. That is one big flaw of the language.

Kotlin is much more pagmatic (not only) in this regard, what is no surprise coming from a tool vendor.

I also encountered way more IDE bugs in Scala than in Java. Actually during the full last year of development of a real-world commercial Scala project I encountered 0 bugs in Java and 2 bugs in Scala.

What about more objective measures? Scala plugin issue tracker: 11667 issues. Kotlin plugin issue tracker: 17664 issues.

And this difference is despite Scala being longer on the market and being more popular than Kotlin.

It looks like Scala IDE support is actually better than that of Kotlin.

How on earth is this an objective measure for plugin quality? There's so much you can interpret into these numbers that they are borderline meaningless.

[pkolaczk]

It is objective measure - it may not be a perfect metric, but definitely objective. If there are more issues relative to the number of programmers this means there are either more bugs, users have more questions, and/or just more feature requests (which means - the plugin is lacking features). Also both plugins share the exactly same bug tracker and the same issue filing process, so you can't argue it is easier to report errors for one over another.

This was back in 2010-2011, so I am sure it has improved 6 years later.

Back then, most of the team was using Eclipse, which was awful! IntelliJ's support was better, even then... but still sluggish.
