It's literally in the linked IntelliJ blog post:

IntelliJ: 72%

Eclipse: 13%

Netbeans: 3%

Who knows how realistic it is though... I personally enjoyed working with Eclipse. It simply suffers from a reputation problem because people developed monoliths with hundred thousands of lines in a single maven project in it...

These numbers are probably very much inflated, they are taken from JetBrains' own survey. One could put a similar survey on eclipse.org and claim that 72% percent of Java developers use Eclipse.

The only time I've ever used Eclipse was when it was mandated by my employer. That happened to me twice.

I didn't stay long at either place - for some reason both companies were horrible places to work.

I have noticed a lot of new grads come out of College knowing Eclipse (and only Eclipse). Which is probably why it persists - and I still have to deal with it when I have to help junior devs figure out what's wrong with their eclipse config. Occasionally I can get one to convert to IntelliJ - the rest won't try a new IDE and that's a pretty good indicator of what kind of engineer they're going to be :)

What if I tried both and find eclipse far more efficient, more to the point, and I have built muscle memory and feel intellij slows me down... Am I that 'kind of engineer'? The tool is fine and works. Especially the barebones 'just plain java please no fucking plugins I'll handle git in terminal and C/C++ in Vim THANKS'.

I understand the annoyance with not being able to fix one's setup and that's on them.

But it seems very strange to fixate on what other people use as tools... Especially when both propositions are on the same productivity level. It's not like your colleagues are coding java in vim (and even then if productive AF, why does it bother anyone?).

I'll clarify: I'm specifically talking about junior devs who are having a lot of trouble with their IDE, have no experience with anything else, and aren't willing to give any other options a shot. It shows a lack of curiosity and/or desire to explore new tools. Some of them don't even know how to do a build outside of Eclipse (worse, I've known some "senior" devs with the same problem).

I know one good senior dev who prefers Eclipse. I'm not sure why, but he doesn't seem to have any major issues with it, and he's good, so... ok.

Every enterprise I have worked at used IntelliJ.
