Java/Kotlin is their main thing, and yet neither Maven nor Gradle builds are stable. If your build fails or there are some unresolved dependencies, you restart IDE in hope it works...
AI coding tool trial failed for me -- IDE told me it's not activated even after I activated it on billing portal. And doc implied it might take some time. WTF. Does it take some batch processing?..
People who were able to get AI coding tools working said it's way behind Cursor (although improving, apparently).
