Compile error for generic type with nested immutable object. (<any> generated) about immutables HOT 2 CLOSED

(duplicate #1380)
It is a problem with not-yet-generated type ImmutableFirstObject. I would suggest, at some point to switch to using only abstract value type in signatures and only use references to generated types in code (inside methods) to instantiate / build instances. All that worked relatively well in Java6–8 and Maven, after that compilers changed a lot and also build tools (like Gradle) introduce more sophisticated ways to isolate annotation processors so this (specifically: using not-yet-generated type in signatures, as attribute types of other values, as params or return types etc) is no longer works reliably in the face of Java / tools upgrades. Need to update documentation to reflect this, but anyway. Currently this is a territory of undefined behavior on part of compiler: should it retain information about not found symbol and keep it as was specified in the source code (just having and error flag/type) or turn it into obscure <any>

I would suggest to try newly released 2.10.0 it has some fixes, possibly related. Also, for build tools it helps to try

1. Switch off incremental compilation or any cool isolation mode for the annotation processor
2. In Gradle, use options.sourcepath on Javac configuration to point to the sources root, this might help Immutables to peek into sources (during compilation) and see un-mangled type (instead of <any>)

from immutables.

Hi @elucash , thanks for suggestion. The problem has been resolved when using options.sourcepath to point to the sources root.

options.sourcepath = files(sourceSets.main.java.srcDirs)

from immutables.
