Answer 1

我更新了我的gradle /wrapper/gradle-Wrapper.properties文件中的"distributionUrl“，以匹配当前的gradle版本。

我还更新了顶级build.gradle文件中的类路径，以匹配gradle API级别。

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

重新同步，然后它建立了OK。

Answer 2

删除版本之间的空格：

implementation "com.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler:$supportVersion"

此外，请将依赖项块移出android块：

android {
...
}
...
dependencies{
...
}

Answer 3

因为您的build.gradle中有错误的块。看起来你把顶级 build.gradle和模块build.gradle混合起来了。您的应用程序模块build.gradle应该如下所示：

apply plugin: 'com.android.application'

android {
  compileSdkVersion 27
  buildToolsVersion '27.0.3'

  defaultConfig {
    ...
  }
  buildTypes {
    release {
      ...
    }
  }

  ..
}

dependencies {
  ...
}
