无法更新特定项目的 gradle 版本：Android Studio

Question

我正在使用以下版本 安卓工作室：3.5.1

classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'me.tatarka:gradle-retrolambda:3.7.1'

project.ext.minSdkVersion = 21
project.ext.compileSdkVersion = 27
project.ext.buildToolsVersion = '27.0.3'
project.ext.supportLibVersion = '27.0.0'

在应用程序中

dataBinding {
        enabled = true
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

和 gradle wrapper 属性是：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip

现在我想更新项目 gradle。

classpath 'com.android.tools.build:gradle:3.3.2'
classpath 'me.tatarka:gradle-retrolambda:3.7.1'// we cannot use it for gradle updated versions 

project.ext.minSdkVersion = 21
project.ext.compileSdkVersion = 28
project.ext.buildToolsVersion = '28.0.2'
project.ext.supportLibVersion = '28.0.0'

这里显示了删除retrolambda的错误，显示了影响项目的lambda方法的compileOptions remove。

每当我尝试仅更新 3.0.0 的 gradle 版本而没有任何其他项目 ext 更新时，它都会向我显示绑定错误 BR。

请检查 gradle 中的所有依赖项。

请试试这个解决方案：

项目分级。

dependencies {
     classpath 'com.android.tools.build:gradle:3.3.2'
