Question

我最近决定将我们公司的android应用程序移植到kotlin中。它运作良好，但是，当我使用任何kotlin扩展时，我得到一个奇怪的行为。我注意到任何使用扩展的类（无论是anko还是自我声明的扩展）只是第一次构建，并且在每个后续构建中它不存在于其他类中。不使用扩展的Kotlin类始终正确构建。每当我运行程序时，这会导致NoClassDefFoundError（在后续构建中，第一个运行没有问题）。我已经尝试了一切，我开始有点绝望了...... 这是整个项目的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 {
}

这是我试图在

以下是该模块的清单（或者更确切地说，它是代码为propietary的标题）

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

Answer 1

好的，所以我设法弄清楚了，也许它会帮助别人。显然问题是java注释（@DebugLog, @NonNull, @Icicle等），如果它们存在于任何kotlin类中，它将半随机编译。在移除它之后它可以完美地工作。

包含android-extensions的Kotlin类不是建立在后续构建上的
