org.gradle.api.gradleexception: lint found fatal errors while assembling a release target.

How to find error details:
1) Anylyze -> Inspect Code
2) Then in Inspection Results you will see an error
3) In my case build failed due to "Suspicious namespace and prefix combination" in the layout deceleration as shown blow code:
xmlns:app="http://schemas.android.com/tools"
(Suspicious namespace and prefix combination)
Also, find similar error issues: unresolved javadoc reference in Google IAP and see how to find such error details

SOLUTION CODE:

change the code xmlns:app="http://schemas.android.com/tools" with this: xmlns:app="http://schemas.android.com/apk/res-auto"

Caused by: org.gradle.api.GradleException: Lint found fatal errors while assembling a release target.
To proceed, either fix the issues identified by lint, or modify your build script as follows:

...

android {

    lintOptions {

        checkReleaseBuilds false

        // Or, if you prefer, you can continue to check for errors in release builds,

        // but continue the build even when errors are found:

        abortOnError false

    }

}
