Cannot change dependencies of configuration - intellij-idea

Question

After I added copyBootstrap to build.gradle I am getting the next error when try to run the build task:
FAILURE: Build failed with an exception.
What went wrong:
A problem occurred configuring root project '.
Cannot change dependencies of configuration ':providedCompile' after it has been included in dependency resolution.
How could this issue be solved? I have searched on Internet but no solutions were found. I got the copyBootstrap task from this link. Their goal is to extract all content from org.webjars group jars to a specific path.
I am using Gradle 3.2 and Intellij IDEA 2016.2.5
//group 'org'
//version '1.0-SNAPSHOT'
task wrapper(type: Wrapper) {

This problem seems to be related to the org.akhikhl.gretty plugin you are trying to use. If I try to build a project using the above gradle file I get the following output:
C:\ws\PLAYGROUND\test123>gradle wrapper --stacktrace
Changed dependencies of configuration ':providedCompile' after it has been included in dependency resolution. This behaviour has been deprecated and is cheduled to be removed in Gradle 3.0.
Changed dependencies of parent of configuration ':compile' after it has been resolved. This behaviour has been deprecated and is scheduled to be removed in Gradle 3.0
Changed strategy of configuration ':compile' after it has been resolved. This behaviour has been deprecated and is scheduled to be removed in Gradle 3.0

That is the gretty plugin seems to use functionality that has been removed with gradle 3.0
There is issue #306 that has been reported a short time ago which describes pretty much your problem.
Given the number of open issues for such a small project and the lack of activity on the issues, I don't think this plugin is much of a help and you will probably be better off using something different.
