Strange "Could not get unknown property 'projectConfiguration' for DefaultProjectDependency" error in multi-project in gradle 4.1

[leiwei2094]

I have a project contains two modules, api and service.
The service depends on the api module.
dependencies { compile project(':api') }
But I get below warning:
Could not get unknown property 'projectConfiguration' for DefaultProjectDependency
And the service module can not access the classes in api.

The Gradle version is 4.1. And I also test the Gradle 2.14.1. It works fine in Gradle 2.14.1.

From the provided information I can only assume you are trying to import a new Gradle project into an older version of IntelliJ IDEA. Please upgrade to the latest version.

If that doesn't fix the issue, please provide a reproducible example project and instructions how to reproduce the problem.

Thanks, oehme, you are right. I update the IDEA to latest version, and it works fine now. Thanks a lot.

Thanks @oehme @vangoleo , I had the same problem too.

I am having this problem right now! Specifically, I am getting "Could not get unknown property '[redacted]' for task '[redacted]' of type org.gradle.api.tasks.testing.Test" -- but only in IDEA; this issue does not occur when I run gradle outside of the IDE, on the command line. This is really hurting me because it completely blocks my ability to live-debug my code!
I have tried running gradle clean, both inside and outside the IDE; restarting IDEA(either normally, or using the menu item "Invalidate Caches / Restart"), and even tried to rm -rf my project's .gradle directory.
Unfortunately, my IDE does not indicate any updates currently available(I am on 2017.2.4, "Build #IU-172.4155.36, Built on September 11, 2017"), so I cannot benefit from the previously mentioned "solutions" (nor do I have any other known recourse)! 😞 👎

That's a completely different problem. Please open a bug report including a reproducible example.
