你可以帮我解决Android 3.0中的Gradle构建问题吗？

我是Android Studio新手.以下是我在AS 3.0中的配置:

gradle-> wrapper-> gradle-wrapper.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.2.1-all.zip

build.gradle依赖项(Gradle的Android插件):

dependencies {classpath 'com.android.tools.build:gradle:3.0.0'}

来自Android Studio的Stacktrace:

D:\AppiumAutomation\MobileTest>gradlew assemble --stacktrace

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'MobileTest'.
> Could not resolve all files for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:3.0.0.

我在mySQL中创建了一个数据库表,其中两个列名是"landPhone"和"mobilePhone"来存储电话号码(格式为:123-456-8000表示陆地,098-765-6601表示移动电话).这两列的数据类型设置为VARCHAR(30).数据已插入表中.但在SQL查询后,我发现电话号码已被截断.它显示(例如,上面两个数据)只有landPhone的前三个数字(123),并且在移除mobilePhone的前导'0'(98)后只显示前两个数字.

为什么会这样？
