android - 程序类型已经存在 : kotlinx. coroutines.experimental.EventLoopBase

Question

我的 kotlin android 应用程序出现以下错误

Android issues: (3 errors)

Program type already present: kotlinx.coroutines.experimental.EventLoopBase Message{kind=ERROR, text=Program type already present: kotlinx.coroutines.experimental.EventLoopBase, sources=[Unknown source file], tool name=Optional.of(D8)}

下面是我的依赖和kotlin实验协程

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'androidx.appcompat:appcompat:1.0.0-rc01'
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'

implementation 'org.jetbrains.anko:anko:0.10.5'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.25.0'
implementation 'com.android.support:design:28.0.0-rc01'
}

kotlin {
    experimental {
        coroutines "enable"
    }
}

Answer 1

这是一个 bug在 kotlinx.coroutines 0.25.0.

中引入

版本 0.25.0 以 multi-release JAR 的形式发布并且这样的 JAR 打破了除了最新的 alpha 版本之外的所有 Android 工具。此更改已在 0.25.3 版本中恢复，因此更新 kotlinx.coroutines 版本并使缓存无效就足以解决此问题。
