IntelliJ15 Indexes Indefinitely with Cursive Enabled

[chetmancini]

On launch of IntelliJ 15 or 15 EAP I get an infinite progress bar "Scanning files to index" / "Indexing..."

I assumed it was a bug with IntellJ so I contacted JetBrains support and they had me investigate the idea.log file. It contains the following (which repeats over and over). Disabling Cursive results in IntelliJ15 working normally. IntelliJ14 with Cursive works fine, so this issue is just with 15 I believe.

I'm using version 0.1.70 from the https://cursiveclojure.com/plugins-15.xml repository.

Possible dupe of https://github.com/cursiveclojure/cursive/issues/1154? Stacktrace looked a little different and versions different. Happy to close this and combine with the other if you'd prefer though.

[cursive-ide]

Yeah, it's possible. Unfortunately your stacktrace doesn't actually have anything Cursive-related in it, or give any clues as to where the problem might be. Is the problematic project open source or proprietary? I'll try to reproduce and fix #1154 and see if that helps your case.

[chetmancini]

@cursiveclojure awesome, thanks. If you have suggestions on how to get more diagnostic information to isolate I'm happy to help in any way. We have a combination of OS and proprietary, so I'll test a few projects and see if there are different behaviors.

[cursive-ide]

@chetmancini Thanks, that would be great. In particular, if you can reproduce it in a project I can look at that would be very helpful. Right now I can't reproduce #1154 so I'm a little short on ideas for how to proceed.

[cursive-ide]

@chetmancini Actually, there's something else you could try - if you can reproduce this reliably, could you go to Help->Enable Debug Log Categories and add "#com.intellij.openapi.project.DumbServiceImpl" there, then reproduce the problem and mail your log to cursive@cursiveclojure.com?
