包含android扩展的Kotlin类-不构建在后续构建之上。

Question

我最近决定将我们公司的android应用程序移植到kotlin。但是，当我使用任何kotlin扩展时，我的行为都很奇怪。我注意到，使用扩展的任何类(无论是anko，还是自声明扩展)都只是第一次构建，而在每次后续构建时，其他类中并不存在此类。不使用扩展的Kotlin类一直都是正确构建的。每当我运行程序时，这就会导致一个NoClassDefFoundError (在后续的构建中，第一个没有问题地运行)。我什么都试过了，我开始有点绝望的…下面是我整个项目的build.gradle：

    buildscript {
    ext.kotlin_version = '1.0.1-2'
    ext.support_version = '23.3.0'
    ext.anko_version = '0.8.3'
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
        classpath 'com.google.gms:google-services:2.0.0-alpha6'
        classpath 'org.codehaus.groovy:gradle-groovy-android-plugin:0.3.7'
        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
    }
}

allprojects {
}

下面是该模块的清单(或者更确切地说，它的标题是丙型的)

<manifest package="com.package.name"
          xmlns:android="http://schemas.android.com/apk/res/android"
          android:versionCode="23"
          android:versionName="0.9.1">

好吧，所以我想出了办法，也许它能帮到别人。很明显，问题在于java注释(@DebugLog, @NonNull, @Icicle等)，如果它们存在于任何kotlin类中，它就会进行半随机编译。去除后，它的工作完美无瑕。
