Hi Mariano,

It’s not immediately obvious what could be causing this problem, particularly since there’s an interaction between Gradle and Spring Boot going on here.

Could you put together the simplest possible project that reproduces this stack trace and share it with us? The ideal thing would be to publish the project to your GitHub account and paste the link here. Thanks!

@cbeams For sure, I’ll post the link today.

Forgot to mention, I’m using spring-boot version 1.2.4

Hi Mariano,

thanks for providing the example. I was able to track down the problem: It looks like the 1.2.x version of the Spring boot Gradle plugin is calling add on a collection returned by ModuleDependency#getExcludeRules here. This is an immutable collection when it is empty for performance reasons since Gradle 3.0. The plugin should call ModuleDependency#exclude instead.

It looks like the Spring boot Gradle plugin 1.4.0.RELEASE works with Gradle 3.0. I do not know if there are still releases of the 1.2.x series of Spring boot.

Regards,
Stefan

@Stefan_Wolf I see. Thanks for the heads up. Will give it a try with spring-boot 1.4.x.RELEASE.

@Stefan_Wolf I can confirm that gradle 3.0 is working fine with spring-boot 1.4 gradle plugin.

Thanks for the help

I think I can’t close the ticket but feel free to do it.
