Java errors during Erlang compilation
Very often when I compile Erlang in IDEA I get different Java errors as a result, the latest I received was:
Error:Erlang '<module_name>': java.lang.IllegalArgumentException: Equal objects must have equal hashcodes. During rehashing, Trove discovered that the following two objects claim to be equal (as in java.lang.Object.equals() or TObjectHashingStrategy.equals()) but their hashCodes (or those calculated by your TObjectHashingStrategy) are not equal.This violates the general contract of java.lang.Object.hashCode(). See bullet point two in that method's documentation. object #1 =Rebar (class org.jetbrains.jps.model.ex.JpsElementChildRoleBase), hashCode=1860295362; object #2 =Rebar (class org.jetbrains.jps.model.ex.JpsElementChildRoleBase), hashCode=1860295362
Where <module_name> is an arbitrary module name.
This particular error happened when I was trying to 'Rebuild Project'.
I usually need to close/open my project to fix this.
I just got one more error, this time when I was doing 'Make Module':
Error:prepare files target: java.lang.NullPointerException
Thank you @istocniks, I'll take a look at it.
Could you share logs, please?
I'm happy to share anything you need :) Which logs are you interested in?
Both IDE logs and build-logs would be great. You can find them via Help -> Show Logs in ***
Thank you for information about build. I'm going to fix problem with NullPointerException tomorrow.
@istocniks
The NPE will no longer occur - but, please, check your build logs for a string "Unexpected dirty file detected." - it would be interesting to know why it happened in the first place.
As to the IAE, it was a nasty concurrency bug, which is now fixed.
Thank you once again for you help!
A dumb follow up question, how should I build the new plugin version? It's all gradle now and I never used it before. I tried to do gradle build and install build/libs/Erlang-0.5.SNAPSHOT.jar but IDEA started to throw java.lang.NoClassDefFoundError: org/intellij/erlang/jps/model/ErlangIncludeSourceRootType after that
You already have it built =)
Use build/distribution/Erlang-0.5.SNAPSHOT.zip to install it.
Found some dirty files today:

I changed some paths for privacy, this happened when I tried to Make Module proj1 which depends on proj3 and proj4
Good, we'll now figure out what's going wrong, if anything,
Could you, please explain how these directories map to you IntelliJ project and module roots?
/Users/istocniks/src here is a project root, each proj is an IntelliJ module
proj1 depends on proj3 and proj4,
proj4 depends on proj3
proj2 depends on proj3
Any updates on this? It seems like now when this error silently occurs resulting beams become corrupted, I cannot reload them and need to re-build the whole project to fix this. At least before a saw the error and new beforehand that I need to re-build stuff differently.
So I've setup a project as you described, changed files in module proj2 and proj1, and ran Make Module proj1.
This gave me the following log entries:
2015-10-22 14:10:31,281 [ 90598] WARN - lang.jps.builder.ErlangBuilder - Unexpected dirty file detected. Please, report to https://github.com/ignatov/intellij-erlang/issues/685. Path: /home/user/IdeaProjects/erl685/proj2/src/module2.erl

Which does make sense - we're not building proj2 because neither proj1 nor any of it's dependencies depend on it. Or do you expect changed modules from proj2 to be built as well?
In your case a file from proj1 is reported as unexpected, which confuses me - it's in the module you claim you're building. Could you try to make a sample project which can be used to reproduce the issue?
Yes, the module I'm building get's corrupted, and if I'm not mistaken, it's not just a project it's a file I changed that is reported dirty. Again don't remember for sure but it's possible that this file was just added to the project.
Well, that may be a clue. What do you mean by 'just added'? Was it added from IntelliJ, or was it some external change?
Then it could only be reported as unexpected, if you've added it after Make was started. It's probably something else...
I've recently pushed a change which affects dirty files set computation before the actual build takes place. Try it out, and let me know if the issue persists.
Gradle build fails on test phase with errors like:

Try running clean task, or use the latest build from https://github.com/ignatov/intellij-erlang/releases
The master branch has been switched to IntelliJ 15. A plugin compatible with IntelliJ 14 can be built from the 141 branch, but it doesn't have these changes yet.
Can you update to IJ15, or should I cherry-pick those changes instead?
Isn't it possible to keep the plugin backwards compatible with 14? Not everyone will upgrade to 15, I definitely don't want to do this before it's released
It's not possible, as there were some API changes between IJ 14 and IJ 15. So we'll have to back-port the changes to make it possible.
BTW, IJ15 was released today =)
