Completion completely broken with --next in hxml

[tobil4sk]

In Haxe 4.2.5, if the hxml contained --next, completion worked normally and it just used the first build found in the hxml.

However, with 4.3.0 development builds since 7ebd72bbe61648193d436106f70ae1a298f82b3c, completion/hovering completely fails as soon as there is a --next flag in the hxml that is followed by anything. Here is a sample hxml:

-main Main
--interp
--next
-main Main
--interp

This is the error that shows up in the vshaxe output:

Oh no...

I'm seeing an error on readClassPaths already:

Hm, wasn't happening for me before but now I made a fresh empty project, and it is:

[Simn]

It only happens if you trace("Hello World") because then the output gets messed up... x)

The other problem is probably related to --cwd in some way.

[Simn]

I made it stop after the first compilation if there's a --display. That's not very elegant, but if this is what used to happen anyway then it should be fine.

[tobil4sk]

if this is what used to happen anyway then it should be fine.

Well, this is what it looked like at least, because when hovering over define flags they would always have values from the initial build before the --next. Also, only --cmds from the first batch used to run, although now it seems like all --cmd flags might be ignored during display runs.

But thanks! Completion is working again now. Not sure how I didn't come across this issue earlier...
