当我尝试构建我的android项目时，它显示了gradle错误。错误如下，

Error:Could not find com.android.tools.build:gradle:2.2.3.
Searched in the following locations:
    https://repo1.maven.org/maven2/com/android/tools/build/gradle/2.2.3/gradle-2.2.3.pom

如果有人知道如何解决此错误，请帮助我。

我的 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
}

根据这个答案https://stackoverflow.com/a/39654136/8284461，也许您需要在存储库中添加mavenCentral()。 gradle会像这样

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
}
