Configuration 'androidTestCompile' is obsolete and has been replaced with 'androidTestImplementation

Android Studio 3.1.2遇到的一个项目编译错误，是配置里面有些api过时了：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:support-core-ui:25.3.1'
    compile 'com.android.support:design:25.3.1'
    testCompile 'junit:junit:4.12'
}

需要改成如下： 
compile 改成implementation 
androidTestCompile改成androidTestImplementation 
testCompile 改成testImplementation

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:25.3.1'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:support-core-ui:25.3.1'
    implementation 'com.android.support:design:25.3.1'
    testImplementation 'junit:junit:4.12'
}
