I use Markdown with Jekyll because it integrates nicely with GitHub Pages and I can run it locally for authoring. There’s tons of support for it, as far as I can tell. Jekyll uses Liquid for templating, and it seems pretty good. For layout, I use Minimal Mistakes which has a really nice feel and it’s comparatively easy to customize. Once I was through all the layout configuration stuff, it’s really just a matter of writing articles and pushing them up to GitHub - rarely fiddle with anything technical these days.
It just works. I spent years with Eclipse (but quite some time ago now), and it was always a pain getting particular things to work properly. The last time I messed with it was doing research for an article I was writing. I was try to get Gradle support enabled. I wasn’t able to do it, but I admit I gave up pretty quickly because I don’t have the patience for messing with tools that don’t work any more.
In truth, I really liked the Open aspect of Eclipse and I wish it work better than Intellij. Maybe it does now - I don’t know. For Java Intellij is awesome, and does everything you could ever dream for. For Kotlin - well Kotlin is an Intellij product and the support for it is awesome.
