如何解决构建签名 Apk 时出现 ClassCastException
我的 gradle 依赖是
repositories {
google()
mavenCentral()
// maven { url "http://maven.ghostscript.com" }
maven { url 'https://jitpack.io' }
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
使用这些应用依赖
buildTypes {
release {
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
packagingOptions {
exclude 'meta-inf/DEPENDENCIES'
exclude 'meta-inf/NOTICE'
exclude 'meta-inf/NOTICE.txt'
exclude 'meta-inf/LICENSE'
exclude 'meta-inf/LICENSE.txt'
}
kotlinoptions {
jvmTarget = '1.8'
}
}
dependencies {
implementation filetree(dir: "libs",include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'

在创建发布签名的 Apk 时出现此错误,我该如何解决?删除 gradle 缓存并无效并重新启动 Android Studio 时无法解决这些错误。
java.lang.classCastException: com.android.tools.r8.s.b.C 不能转换为 com.android.tools.r8.s.b.B
com.android.tools.r8.CompilationFailedException:编译失败,位置:Lorg/readium/r2/streamer/parser/epub/OPFParser;parseSpine(Lorg/readium/r2/shared/parser/xml/Node; Lorg/readium/r2/shared/Publication;)V,来源:C:\Users\Asif Malik.gradle\caches\transforms2\files2.1\202fad4fee5b15436e55e2114f613e17\jetified-r2streamerkotlin1.0.42/org/流光/解析器/epub/OPFParser.class
com.android.tools.r8.s.b.C 不能转换为 com.android.tools.r8.s.b.B
Gradle 的依赖缓存可能已损坏(这有时发生在网络连接超时之后。)
重新下载依赖并同步项目(需要网络)
Gradle 构建进程(守护进程)的状态可能已损坏
解决方法
这是在 http://issuetracker.google.com/175132220 中跟踪的 R8 问题。
