Question

我正面临数据绑定和kapt的问题我在Android Studio 3.2.1中使用kotlin 问题是当我使用kapt时（如果我想使用DBFlow，我必须使用kapt），构建会失败。

我尝试了几种解决方案，例如使缓存无效，重新启动或清理项目并重建，添加或删除kapt'com.android.databinding：compiler：3.1.4' 但是将它与最新版本的kapt一起添加显然没用

这是项目的gradle文件

buildscript {
    ext.kotlin_version = '1.3.10'
    ext.dbflow_version = '4.2.4'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        mavenCentral()
        maven { url "https://www.jitpack.io" }
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

应用程序的gradle文件

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

android {
    compileSdkVersion 28

    defaultConfig {
        applicationId "paf.songrecorder"
        minSdkVersion 16
        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'
        }
    }
    dataBinding {
        enabled = true
    }

    androidExtensions {
        experimental = true
    }

    kapt {
        generateStubs = true
    }

}

dependencies {
    annotationProcessor "com.github.raizlabs.dbflow:dbflow-processor:$dbflow_version"
    kapt "com.github.raizlabs.dbflow:dbflow-processor:$dbflow_version"

    implementation "com.github.raizlabs.dbflow:dbflow-core:$dbflow_version"
    implementation "com.github.raizlabs.dbflow:dbflow:$dbflow_version"
    implementation "com.github.raizlabs.dbflow:dbflow-kotlinextensions:$dbflow_version"

    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

构建应用程序时，在DataBinderMapperImpl类中找不到BindingImpl类

[编辑]

我在未添加以下行的情况下遇到此错误：

import paf.songrecorder.databinding.SongBindingImpl; ^ symbol: class SongBindingImpl location: package paf.songrecorder.databinding – PAF 11 mins ago

添加后 kapt“ com.android.databinding：compiler：$ android_plugin_version”：

您是否知道可能导致此问题的原因？

请参考https://stackoverflow.com/a/54071510/1726296

的回答

从Android Studio 3.2开始，不再需要此kapt插件。

但是，如果没有此插件，则在编译时如果出现任何错误，则会显示错误消息。因此，现在看来唯一的选择就是将您的Gradle版本降级为3.1.4。
