Can't load the whole Quarkus project in IntelliJ anymore?

[Jaikiran Pai]

Until recently I used to be able to load the entire quarkus Maven
project into IntelliJ (all modules including integration tests).
However, this week I haven't been able to load the existing project nor
reimport the whole project afresh, into IntelliJ. It keeps giving
OutOfMemory - Heap space (I even increased the max heap to 4GB for
IntelliJ). Looks like we now have 870+ Maven modules in the project.

Is anyone here able to load the whole project into IntelliJ. Basically
creating the project afresh and pointing IntelliJ to load from the root
of the Quarkus Maven project? How much heap have you set for IntelliJ?
If loading the whole project isn't going to work anymore, is there some
specific set of modules you all load? So far I had found that loading
the whole set was very benefial in quick debugging and fixing of issues
within Quarkus, but looks like that's not going to work anymore given
the ever increasing number of modules.

I had the same problem as well. And was able to fix it with the following settings:

Help -> Change memory settings -> set to 4096

File -> Settings -> Build, Execution, Deployment -> Build Tools -> Maven -> Importing -> VM options for importer -> set to -Xmx4g -Xms1g

Hope this helps!

Was about to write what Ivan send. Thanks Ivan :)

Yes, in IDEA there are 2 memory settings, one for the IDE and another one for the Maven importer. I had the same issue in the past and I setting the memory for the Maven importer did the trick.

Cheers,

Roberto

Setting the Maven VM importer options did the trick and I can now load the whole project again. Thank you Ivan and Roberto :)

Thanks Ivan and Roberto, this helped me too.

Is there any benefit for setting it even higher? I seem to recall in the old days, that having too-high memory settings resulted in long GCs. I'm about to upgrade my Mac Mini to 64GB, so I want to make the most of the extra capacity if I can. 

(64GB is probably overkill (for my needs), but it's also a hassle to do the upgrade and I don't want to have to do it again!)

Paul.

I fix it by using eclipse or just importing subparts :)

Can one of you who torture yourself by importing everything update
https://github.com/quarkusio/quarkus/blob/main/CONTRIBUTING.md
so we have this at least documented for others?

It is already in there. I missed it, too.. and felt pretty silly when I figured out the maven importer settings and went to update the CONTRIBUTING.md file myself to find it was already there..

Right. I've had to point contributors to it several times, and now I see most of you didn't know either.

Clearly that's not where people look for it.

FWIW I added these specific instructions about heap size just a few weeks ago (Feb. 16th), so anyone reading the guide before that wouldn't have seen them.

Maybe I should open a new thread for this, but I'll try here.

After loading the whole project in IntelliJ IDEA, are you able to build it with Build -> Build Project (Ctrl + F9)? This is run automatically by the IDE upon running any unit test.

Because I get this:

And if I try to switch off building the project from the run configuration, then I get:

java.lang.NoClassDefFoundError: io/quarkus/arc/Arc

I remember being puzzled by Yoann's comment ^ as I did point to similar instructions long before Feb. 16th, and finally figured it out: there are two sections in the same file now.

Fixing it [1], but this just confirms what I said in my previous email: people don't read it all

In this PR I also make use of the .mvn/jvm.config file in the project, as I've just learned that the Maven importer in IDEA will take that into account; it actually takes that into account  better than its own explicit settings, which is why so many contributors were in trouble recently [2].

I think that's ideal as people will no longer have to read (they didn't anyway..) but I hope we won't get in trouble with the defaults I've proposed, e.g. 8G might be too much for CI to handle?

Having a low Xms and generous Xmx should get us a long way I hope but this might need a little refining, and it would certainly help if we could lower the requirements.

I had bunch of errors (after sorting out the OOM issues) which were similar to what you describe here. Basically, the IntelliJ IDE was unusable for me this past week and I didn't have time to investigate more. Today they released 2021.1 version of IntelliJ and I just upgraded to it and I no longer see these errors/ClassNotFound/NoClassDefError anymore. I think it's worth to just upgrade to this version and see if it fixes these issues.
