When I try to build my android project it shows some gradle error. The error is as follows,

Error:Could not find com.android.tools.build:gradle:2.2.3.
Searched in the following locations:

If anybody know how to fix this error please help me.

my build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }

    dependencies {

        classpath 'com.android.tools.build:gradle:2.2.3'

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

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 1

This is because the build process is unable to find the dependency in Maven repository. Add jcenter() along with mavenCentral() in your project level build.gradle file.

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0'
    }
}

Answer 2

according to this answer https://stackoverflow.com/a/39654136/8284461, maybe you need to add mavenCentral() in your repositories. the gradle would be like this

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }

    dependencies {

        classpath 'com.android.tools.build:gradle:2.2.3'

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

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
