Unable to build standalone IDE due to unknown circular dependency

Build script@0 contains some strange ?language?: 

?language? were caused by missing "com.mbeddr.mpsutil" dependency in idea plugin group.

After I added it, st61131@0 looks as follows (no red parts), yet the same "circular dependency" error while rebuilding "build" solution:

build st61131 generates build.xml

Finally, I removed all languages/solutions but "very dummy solution" from the build scripts. That ensures build script work (at least, they produce executable binaries for OSX)

So the question is how to debug build script translator ("generator" in mps)?
It looks like I can set a break point there, however it does not stop there.

1. Have you udpated your build scripts after removing dependency cycle (Reload modules from disk)?

2. To debug MPS (e.g. generator) from MPS you need two separate MPSs. It can be done with "MPS Instance" run configuration. But I think this will be rather slow in your case.

3. You can also debug MPS from any java debugger, e.g. Intellij IDEA. For this you should enable debugger port before starting MPS, then connect debugger to MPS instance using this port and set breakpoints in generated java code.

1) Of course I did.

Then I remembered "death by using quotations" and converted all the quotations to light quotations ("find concept instances" shows zero entries for Quotation). Then I rebuilt ".types" language just in case. 

TL;DR: removing quotations did not help :(

2) Will see if I could get that working.

3) It means breakpoint should be set from within IDEA, right? Or it even supports setting breakpoints from MPS?

I've scanned through com.mbeddr.platform build script once again, and it turns out it uses bootstrap=true.

I think it might mean there's some cyclic dependency hidden in there.
