无法使用Kotlin将领域集成到android库模块中

Question

我的顶级build.gradle

apply plugin: 'kotlin'


buildscript {
    ext.kotlin_version = '1.3.30'
    repositories {
        mavenLocal()
        google()
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
        //region realm
        maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local' }
        //endregion
    }
    dependencies {
        //region google()
        classpath 'com.android.tools.build:gradle:3.3.2'
        //endregion
        //region jcenter()
        classpath 'com.google.gms:google-services:4.2.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        //endregion
        //region maven { url 'https://maven.fabric.io/public' }
        //to check fabric gradle ver
        //https://s3.amazonaws.com/fabric-artifacts/public/io/fabric/tools/gradle/maven-metadata.xml
        classpath 'io.fabric.tools:gradle:1.+'
        //endregion
        //region realm
        classpath "io.realm:realm-gradle-plugin:5.8.0"
        //endregion
    }
}

这是我的图书馆模块build.gradle

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'realm-android'

android {
    ...

    defaultConfig {
        ...
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "com.android.support:appcompat-v7:${supportLibVer}"

    implementation "io.reactivex:rxjava:${rxJavaVersion}"
    implementation("io.reactivex:rxandroid:${rxAndroidVersion}") {
        exclude group: 'io.reactivex', module: 'rxjava'
    }

    implementation("com.github.davidmoten:rxjava-extras:${rxExtrasVersion}") {
        exclude group: 'io.reactivex', module: 'rxjava'
    }

    implementation('io.reactivex:rxjava-math:1.0.0') {
        exclude group: 'io.reactivex', module: 'rxjava'
    }

    implementation "com.google.dagger:dagger:${daggerVersion}"
    implementation("com.google.dagger:dagger-android-support:${daggerVersion}") {
        exclude group: 'com.android.support', module: 'appcompat-v7'
        exclude group: 'com.android.support', module: 'support-annotations'
        exclude group: 'com.android.support', module: 'support-fragment'
    }
    annotationProcessor "com.google.dagger:dagger-compiler:${daggerVersion}"
    kapt "com.google.dagger:dagger-compiler:${daggerVersion}"
    annotationProcessor "com.google.dagger:dagger-android-processor:${daggerVersion}"
    kapt "com.google.dagger:dagger-android-processor:${daggerVersion}"
    implementation "javax.inject:javax.inject:${javaxInjectVersion}"
    implementation "javax.annotation:jsr250-api:${javaxAnnotationVersion}"
    implementation "com.android.support:support-annotations:${supportLibVer}"

    ...
}

结果我无法进行Sync，错误是：

ERROR: Unable to resolve dependency for ':module@debug/compileClasspath': Could not resolve all dependencies for configuration ':module:debugCompileClasspath'.

Affected Modules: module

但是如果我远程

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'

然后一切正常

发现的问题：是因为我有failOnVersionConflict()最高构建gradle

解决此问题：顶部build.gradle文件：

buildscript {
    ext.kotlin_version = '1.3.31'
    repositories {
        mavenLocal()
        google()
        jcenter()

        //region realm
        maven { url 'http://oss.jfrog.org/artifactory/oss-snapshot-local' }
        maven { url 'https://dl.bintray.com/realm/maven' }
        //endregion
    }
    dependencies {
        //region google()
        classpath 'com.android.tools.build:gradle:3.3.2'
        //endregion
        //region jcenter()
        classpath 'com.google.gms:google-services:4.2.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        //endregion

        //region realm
        classpath "io.realm:realm-gradle-plugin:5.11.0"
        //endregion
    }
}

allprojects {
   ...

    configurations.all {
        exclude group: 'org.jetbrains.kotlin', module: 'kotlin-stdlib-jre7'

        resolutionStrategy {
            // fail eagerly on version conflict (includes transitive dependencies)
            // e.g. multiple different versions of the same dependency (group and name are equal)
            failOnVersionConflict()

            //this is needed:
            force "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version",
                    "org.jetbrains.kotlin:kotlin-android-extensions-runtime:$kotlin_version",
                    "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version",

        }
    }
}
