AssertionError：必须初始化Root包

Question

我在Android Studio中的另一台计算机上打开我的Kotlin项目，并在事件日志中遇到错误：

  

AssertionError：必须初始化Root包

Root package must be initialized

项目主体结构：

的build.gradle

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

android {
compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "taskmoney"
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.pro'
    }
}
sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
    local.java.srcDirs += 'src/local/kotlin'
    }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
//dependencies list
}

buildscript {
ext.kotlin_version = '0.12.1230'
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.2.3'
    classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

因此，无法打开任何.kt文件。

猜猜我想念一些简单的事......谢谢

我认为这是因为Android Studio IDE的版本。我在使用1.2时遇到了同样的问题，在我升级到1.5后，问题解决了。
