IntelliJ 2018.2 constantly re-indexing when Android Support turned on.

[gspencergoog]

Tonight I updated to:

IntelliJ IDEA 2018.2 (Community Edition)
Build #IC-182.3684.101, built on July 24, 2018
JRE: 1.8.0_152-release-1248-b8 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.13.6

And IntelliJ now continuously indexes (once a second), causing a lot of things to not work, and interrupting interaction with the UI.

It's similar to #1735, but invalidating caches/restarting or even nuking the .idea directory doesn't help.

What does help is disabling the "Android Support" plugin (with the obvious down side. :-)). That seems to fix the problem, but only until I turn it on again.

The log says repeatedly (once per second):

The problem is probably caused by this issue. Could you please try IntelliJ IDEA 2018.2.1 RC where the problem should be fixed? (You may switch to EAP update channel in Preferences | Appearance & Behavior | System Settings | Updates and check for updates).

@stevemessick for FYI

Reopen if you suspect that you are hitting something else.

[devoncarew]

@jwren, this issue is severe enough that we may want to consider keeping it open until the fix rolls into the stable version of 2018.2, and / or updating our known issues list on the readme and mentioning something in the release notes.

[gspencergoog]

OK, I tried out the EAP version, and indeed it appears to be fixed there. Thanks. I'll stick to EAP until it makes it to stable and then switch back to stable.

[devoncarew]

I updated the readme to reference this issue (109e9f3); we expect the fix to be in the stable version of 2018.2 ~next week.

It is worth keeping this issue open so people like me can more find it and find a resolution. It was driving me bonkers :-)

[devoncarew]

IntelliJ IDEA 2018.2.1 is out, and this does look fixed.
