Migration from 2.7.0 to 2.9.0

[Alexey Kuznetsov]

Hello GWT Users,

I'm trying to migrate very old project from GWT 2.7.0 to GWT 2.9.0

Project build with Gradle.

Everything is working as expected for GWT 2.7.0, but when I update to GWT 2.9.0

build failed with message "[ERROR] Hint: Check that your module inherits 'com.google.gwt.core.Core' either directly or indirectly (most often) by inheriting module `com.google.gwt.user.User`"

I've simply changed version in "build.gradle".

Java compilation succeeded and even window with Dev mode launcher appeared on the screen.

I think it is some misconfiguration. Maybe something changed in GWT 2.9.0 configuration?

Any ideas what am I missing?

Can you share the complete build log? At a guess, there is some classpath mismatch, mixing parts of GWT 2.7 with 2.9 - the Core module is always included as an inherits for every module, even if that module is empty, so this suggests an earlier error that prevented that module from working, or prevented the compiler from finding it.
