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

Android Gradle Sync failed could not find support-core-ui.aar

I've been working on this Android Project for about a year now, suddenly when I opened it yesterday Android Studio 3.1.2 failed to sync gradle and the project doesn't build anymore giving me this error:
Could not find support-core-ui.jar (com.android.support:support-core-ui:27.1.1).
Searched in the following locations:
https://jcenter.bintray.com/com/android/support/support-core-ui/27.1.1/support-core-ui-27.1.1.jar
Please install the Android Support Repository from the Android SDK Manager.
Open Android SDK Manager
I'm pretty sure that the Android Support Repository is installed correctly because it's working successfully in other projects and all my other projects are working fine with no problems.
I have this gradle file in the app module:

Any suggestions or solutions are very appreciated. Thanks.

I just resolved this problem on my own build server. I updated my repositories block in my build.gradle to have google() as the first entry like below:
allprojects {
repositories {
google()
jcenter()
}
}
Edit: removed a repo that was not needed.

Switch from
jcenter()
google()
to
google()
jcenter()

OK, so that's why:
AAPT2 now on Google's Maven repo: To use AAPT2, you must add Google's Maven repository to your project-level build.gradle, as shown below. Learn more
buildscript.repositories {
google()
jcenter()
...
}
allprojects.repositories {
google()
jcenter()
...
}

I added google() in my build.gradle
buildscript {
repositories {
jcenter()
google()
mavenLocal()
maven { url 'https://maven.google.com' }
}
}
allprojects {
repositories {
jcenter()
google()
mavenLocal()
maven { url 'https://maven.google.com' }
}
}
for me it fixed the problem.
You can try it too.

Check if you are working offline.
File > Settings > Write "offline" on the search bar > Gradle > uncheck "offline work".
Use the keyword "implementation" instead of "compile". Compile is deprecated and will be abandoned by the end of 2018. This is a long shot, but something might have changed since the last Android Studio update.
Explicitly add com.android.support:support-core-ui:27.1.1 to your dependencies.
Let me know if it helped.
Good luck.
Update:
If you go to
https://repo.jfrog.org/artifactory/libs-release-bintray/com/android/support/support-core-ui/27.1.1/
You'll find out that your *.jar file is not there.
There are a couple others, though:
support-core-ui-27.1.1-sources.jar
support-core-ui-27.1.1.aar
support-core-ui-27.1.1.pom
You can use the *.aar file instead.

I had this exact problem, realizing I also updated my gradle to 4.8 between my last successful build and the now broken ones. I downgraded back for 4.7 and my continuous integration builds work again.

So I've been able to solve the problem, but maybe just a workaround so at least my CI build passes. It appears that including this line in my gradle dependencies fixed it:
implementation "com.android.support:support-core-utils:27.1.1"
Also I made sure google() is the first one listed in my top-level gradle repository

i have not used v-27 then why i am facing v7 issue
thanks in advance

Add allprojects block in your app level build file
1.
allprojects {
repositories {
jcenter()
maven {
url 'https://maven.google.com'
}}}
2.
New projects created using Android Studio 3.0 and higher also include
allprojects {
repositories {
jcenter()
google()
}}
And change your compileSdkVersion to 26 and also buildToolsVersion "26.0.1" then sync your project
Hope this will help you.

Try this i have same problem i solved using below dependencies of Facebook
Use this
compile 'com.facebook.android:facebook-android-sdk:4.26.0'
instead of this
compile 'com.facebook.android:facebook-android-sdk:[4,5)'

There are dependencies that require the entire hierarchy of modules to include the repository.
With Kotlin DSL
build.gradle.kts (Project)
allprojects {
repositories {
// ...
maven(url = "<YOUR-URL>")
}
}
With Groovy
build.gradle (Project)
allprojects {
repositories {
// ...
maven {
url '<YOUR-URL>'
}
}
}
GL

In my case, I was using old plugin so needed to add
jcenter()
After
mavenCentral()

ClassNotFoundException when referencing Kotlin classes

I try to start migrating a Java based multidexed project to Kotlin but I get ClassNotFoundException whenever the app tries to reference a Kotlin class. The weird thing is that the same code sometimes works sometimes it doesn't. There are computers which produce working apk and others don't. Sometimes a rebuild is enough to solve the problem.
I've tried to google it but I've only found this thread, but there is no resolution. Does this thing work properly for everyone else or aren't there any multidexed Kotlin project yet?
I've tried with AS 2.3.3 and AS 3.0.0-beta6, 2.3.3 android plugun, kotoin version 1.1.50, without proguard.

Finally I was able to solve the issue! The exception was caused by a RetroLambda bug and thankfully disappeared after I updated to 3.7.0. The build was nondeterministic because it seems gradle clean doesn't delete everything. After I manually deleted the build folder both in the app and root module, the results became deterministic.

If you are using Java 8 then you should also use Kotlin jre8.
compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_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'".

Please let me know if I can provide more information for the same. Thank you.

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