Android 显示依赖项错误的渐变

当我将constraint layout版本更改为alpha-2时，它显示错误。以前我使用的是旧版本，它没有显示任何错误：

旧版本工作正常，无错误：

dependencies {
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2' 
}

dependencies {
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2' 
}

出现错误的新版本：

dependencies {
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2' 
}

dependencies {
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2' 
}

格拉德尔：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
  compileSdkVersion 28
  defaultConfig {
     applicationId "com.m3tech.transitionspractice"
     minSdkVersion 21
     targetSdkVersion 28
     versionCode 1
     versionName "1.0"
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
  }
  buildTypes {
      release {
        minifyEnabled false
           proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
  } 
}

dependencies {
     implementation fileTree(dir: 'libs', include: ['*.jar'])
     implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
     implementation 'com.android.support:appcompat-v7:28.0.0'
     implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2' 
 }

错误：

dependencies {
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2' 
}

dependencies {
  implementation fileTree(dir: 'libs', include: ['*.jar'])
  implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2' 
}

改变

implementation 'com.android.support.constraint:constraint-layout:2.0.0-alpha2'

我用这个代码修复了这个问题。将应用程序模块放入build.gradle

：

configurations.all {
    resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "28.0.0"
            }
        }
    }
}

发布您正在使用的所有渐变或依赖项。您只发布了两次相同的代码片段。
