Question

我正在使用 Dokka 插件为我的kotlin项目生成文档

以下是插件网址 https://github.com/Kotlin/dokka

我已按照说明操作，这是 Project.gradle 的样子

buildscript {
    ext.kotlin_version = '1.1.51'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.jetbrains.dokka:dokka-gradle-plugin:0.9.15"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

这是 app / build.gradle 的样子

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'org.jetbrains.dokka'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.kk.testkotlindoc"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dokka {
    outputFormat = 'html'
    outputDirectory = "$buildDir/javadoc"
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

当我执行以下命令生成文档时

./ gradlew dokka

它最初在完成该过程后下载了必要的jar文件，它给出了以下错误

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/KK/AndroidStudioProjects/TestkotlinDoc/app/build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':app'.
> java.lang.UnsupportedClassVersionError-com/android/build/gradle/AppPlugin

不受支持的major.minor版本52.0

但我无法确定问题是什么或我在这里失踪

请帮帮我..

Answer 1

问题是您在较旧的JDK版本下运行Dokka。 Dokka需要JDK 8.请确保您计算机上的环境变量JDK_HOME指向JDK 8安装。

Answer 2

您可以在没有Dokka插件的情况下生成Dokka文档。使用GradleMavenPush，它具有task androidDokka(type: Exec, dependsOn: dokkaInitializer)和task coreDokka(type: Exec, dependsOn: dokkaInitializer)

apply from: 'https://raw.github.com/Vorlonsoft/GradleMavenPush/master/maven-push.gradle'

在Android Studio中使用Dokka为Kotlin项目生成Javadoc Kdoc时出错
