Facing the issue while gradle sync - Could not find lint-gradle-api.jar (com.android.tools.lint:lint-gradle-api:26.1.2)

There were lots of similar issues raised the past days, that could be solved by adding the google() repository in first position in the repositories block of the build scripts. See detailed explanation in the following answers:

• couldn't locate lint-gradle-api-26.1.2.jar for flutter project
• Could not find play-services-basement.aar
• https://stackoverflow.com/a/52982816/6899896
• Could not find com.android.tools.build:aapt2:3.2.0

The root cause , related to missing libraries in Jcenter, is explained in detail here : https://stackoverflow.com/a/50885939/6899896

Note see https://stackoverflow.com/a/52947028/6899896 : you need to modify .flutter/packages/flutter_tools/gradle/flutter.gradle in addition to your project's build scripts (module & app levels) to set repo google() first and jcenter() last

In case you're actually trying to run a Flutter project, you also need to change the order in the flutter gradle file:

<flutter directory>/packages/flutter_tools/gradle/flutter.gradle

I also updated gradle to the latest version (https://docs.gradle.org/current/userguide/installation.html) and restarted Android Studio

TL;DR:

1. Open <flutter_dir>\flutter\packages\flutter_tools\gradle\flutter.gradle

2. Replace buildscript with this (the order of repositories does matter)

     buildscript {
       repositories {
         jcenter()
         maven {
           url 'https://dl.google.com/dl/android/maven2'
         }
     }
     dependencies {
       classpath 'com.android.tools.build:gradle:3.1.2'
     }
   }
   

As written in https://flutter.su/note/1, you should find a .gradle-file for your project (in Android it is usually app/build.gradle) and change (an order of repositories makes sense):

buildscript {

    repositories {
        google()
        jcenter()
        maven {
            url 'https://dl.google.com/dl/android/maven2'
        }
    }
    ...
}

...

allprojects {
    repositories {
        jcenter()

        maven {
            url "https://maven.google.com"
        }
        google()
    }
}
