Make sure all support lib have same version.

There are multiple reasons Why you are getting this error,
First one May be your internet is not working properly because as i see you have used a lots of third party libraries so it will require high speed internet to download.
Second one is may be your project setting is in offline mode Check it by go to File -> Settings -> Build , execution , Development and click Gradle and check weather the "Offline" work checkbox is checked or not.
Third one is may be a cache memory just invalidate and restart the project go to File -> Invalidate Caches / Restart.
Hope this help

Did you tried Build/Clean Project in Android Studio Menu

Which dependency does the app:transformClassesWithJarMergingForDebug come from? Maybe you should modify that dependency's version number to be consistent with the major sdk version.

Project with path could not be found in root project Android Studio

Actually few hours ago my project has no error, but I don't know what changes happened from me unknowingly and now I'm getting following error--
"Error:(36, 0) Project with path ':easyAndroidAnimationsLibrary' could not be found in root project 'wikiReviews'".

your project should be wikiReviews.
I guess the way of your project loaded from android studio maybe wrong

“'this' is not available” in debug windows of Android Studio

this might seem a duplicate of "'this' is not available" in debug windows of Android Studio

Just remove Hugo, and the problem will be solved. This issue is duplicated and as been already answer in the following post : "'this' is not available" in debug windows of Android Studio
A issue has been published to the Hugo repo.

I meet the same question.Try this method:make your build.gradle have---------> minifyEnabled false.
Sometime i use this way resolve my problem.

This might help, just a silly thing. If you are using minify, then check if it's enabled in debug
buildTypes {
debug {
minifyEnabled true
}
}
To
minifyEnabled false
