Could not find com.android.tools.build:gradle:2.3.3

Question

I am getting this error during gradle build in android studio. And I am unable to figure out what I am missing.

Error:Could not find com.android.tools.build:gradle:2.3.3. Searched in the following locations: file:/C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/tools/build/gradle/2.3.3/gradle-2.3.3.pom

https://maven.google.com/com/android/tools/build/gradle/2.3.3/gradle-2.3.3.jar

Here is my build.gradlefile configuration

`
all sub-projects/modules.
    allprojects {
        repositories {
            jcenter()
            maven {
                url "https://maven.google.com"
            }
            maven {
                url 'https://jitpack.io'
            }
        }
    }

    buildscript {
        dependencies {
            classpath 'com.android.tools.build:gradle:2.3.3'
        }
        repositories {
            maven {
                url 'https://maven.google.com/'
                name 'Google'
            }
        }
    }

    ext {
        supportlib_version = '26.0.2'
        gps_version = '11.2.0'
    }

    //Ensure that all dependencies use the same version of the Android Support library
    subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.android.support'
                        && !details.requested.name.contains('multidex')) {
                    details.useVersion "$supportlib_version"
                }
                if (details.requested.group == 'com.google.android.gms'
                        && !details.requested.name.contains('multidex')) {
                    details.useVersion "$gps_version"
                }
            }
        }
    }

    allprojects {
        repositories {
            jcenter()
            maven {
                url 'https://maven.google.com/'
                name 'Google'
            }
        }
    }

Could you help me what am I missing?

Add jcenter() to buildscript repositories if you are using gradle plugin 2.x.

Here's a copy of build.gradle(Project) from my old project.

buildscript {
    repositories {
        // for 2.x
        jcenter()
    }
    dependencies {
        // classpath 'com.android.tools.build:gradle:2.2.0'
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

If your gradle (the one distributed by Gradle) version is low,
also need to edit gradle-wrapper.properties.

Minimum version of Gradle is 3.3 for plugin 2.3.3.

Plugin version 2.3.0+ :
Required Gradle version 3.3+

gradle-wrapper.properties sample:

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
#distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip
distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip

Please see Update Gradle. Available versions are listed in this page.

For information:

This exists (jcenter).
https://bintray.com/android/android-tools/com.android.tools.build.gradle/2.3.3

This does not exist (Google's Maven repository). It's from 3.0, I think.
https://maven.google.com/com/android/tools/build/gradle/2.3.3/gradle-2.3.3.pom

This exists
https://maven.google.com/com/android/tools/build/gradle/3.0.0/gradle-3.0.0.pom

For Gradle version >= 3.0.0

Please see Update the Android Plugin for Gradle and Update Gradle.
