添加Room编译器后找不到GlideApp

将房间组件添加到gradle配置文件后，

编译项目失败，错误为“找不到符号类GlideApp”。如果注释掉“注释处理器” android.arch.persistence.room:compiler:$room_version”，则项目编译不会出错。

apply plugin: 'com.android.application'

android {

    compileSdkVersion 27

    defaultConfig {

        applicationId "com.otpuskarche.onleave"

        minSdkVersion 24

        targetSdkVersion 27

        versionCode 1

        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {

        release {

            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }

    }

}

dependencies {

    def room_version = "1.1.1"

    def archLifecycleVersion = '1.1.1'

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:27.1.1'

    implementation 'com.android.support.constraint:constraint-layout:1.1.2'

    annotationProcessor 'com.github.bumptech.glide:compiler:4.7.1'

    implementation 'com.android.support:gridlayout-v7:27.1.1'

    implementation 'com.google.android.gms:play-services-maps:15.0.1'

    // Room components

    implementation "android.arch.persistence.room:runtime:$room_version"

    annotationProcessor "android.arch.persistence.room:compiler:$room_version"

    androidTestImplementation "android.arch.persistence.room:testing:$room_version"

    // Lifecycle components

    implementation "android.arch.lifecycle:extensions:$archLifecycleVersion"

    annotationProcessor "android.arch.lifecycle:compiler:$archLifecycleVersion"

    testImplementation 'junit:junit:4.12'

}

解决：

您需要添加注释处理器依赖项：

annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0-RC0'

您还需要添加一个AppGlideModule。有关详细信息，请参见generated API documentation。
