Question

每当我尝试运行 Kotlin 中的程序时，我都会收到此错误。我的 gradle 文件是这样的：项目级别 Gradle

buildscript {
    ext.kotlin_version = '1.2.30'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:3.2.0'
    }
}
allprojects {
    repositories {
        google()
        jcenter()
    }
}
task clean(type: Delete) {
    delete rootProject.buildDir
}

和应用级别Gradle

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'
ext.supportLibraryVersion = '27.1.1'
ext.playServices = '11.6.2'

        versionCode 1
        versionName "1.0.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    repositories {
        jcenter()
        maven { url 'https://jitpack.io' }
        mavenCentral()
        google()
    }
}

}

每当我尝试运行程序时，我都会收到此错误

Program type already present: org.intellij.lang.annotations.Flow Message{kind=ERROR, text=Program type already present: org.intellij.lang.annotations.Flow, sources=[Unknown source file], tool name=Optional.of(D8)}

Answer 1

请在您的应用程序级别添加以下行 build.gradle。

configurations {
    cleanedAnnotations
    compile.exclude group: 'org.jetbrains' , module:'annotations'
}

Answer 2

排除 jetbrains 注释模块是一种解决方法；为什么它首先出现在您的项目中？最有可能的是，当您真正想要的是 Android 自己的注释时，它会被 Android Studio 自动添加到您的类路径中。

因此，更好的解决方案是在 build.gradle 文件[s]中寻找 org.jetbrains:annotations 依赖项，如下所示：

implementation 'org.jetbrains:annotations-java5:15.0'

...并将其删除。

Answer 3

已经存在的程序类型：

org.intellij.lang.annotations.JdkConstants$PatternFlags

Answer 4

对我来说，这只是一个小故障 - "Clean project" 有所帮助。
