每当我尝试在Kotlin中运行程序时,都会收到此错误。我的Gradle文件如下:项目级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
}

无论何时我试图运行程序,都会出现以下错误: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)}
