Question

我创建了一个全新的Android项目并添加了lombok支持。

当我在Java 7上开发时，一切都运行良好，但是我将语言级别更新为8，lombok编译器停止运行。

我在gradle中为将语言更新为java 8所做的更改是：

jackOptions {
    enabled true
}

和

compileOptions {
targetCompatibility 1.8
sourceCompatibility 1.8

}

我的朋友是：

android {
compileSdkVersion rootProject.ext.compileSdkVersion
buildToolsVersion rootProject.ext.buildToolsVersion

defaultConfig {
    applicationId "com.instatrivia"
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion
    versionCode 1
    versionName "1.0"

    jackOptions {
        enabled true
    }
}


buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

dataBinding {
    enabled = true
}
buildToolsVersion '25.0.0'
compileOptions {
    targetCompatibility 1.8
    sourceCompatibility 1.8
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support.constraint:constraint-layout:1.0.1'
testCompile "junit:junit:$rootProject.junitVersion"

// Android support libs

annotationProcessor "com.google.dagger:dagger-compiler:$rootProject.dagger_version"
//    testApt "com.google.dagger:dagger-compiler:$rootProject.dagger_version"

// rx java/android
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
// Because RxAndroid releases are few and far between, it is recommended you also
// explicitly depend on RxJava's latest version for bug fixes and new features.
compile 'io.reactivex.rxjava2:rxjava:2.0.1'

provided 'javax.annotation:jsr250-api:1.0'
compile 'javax.inject:javax.inject:1'

// misc
provided "org.projectlombok:lombok:1.16.14"
compile "com.google.guava:guava:$rootProject.guavaVersion"
compile "com.squareup.retrofit2:retrofit:$rootProject.retrofitVersion"
compile "com.squareup.retrofit2:converter-gson:$rootProject.retrofitVersion"

compile 'com.google.code.gson:gson:2.2.4'
compile 'org.greenrobot:eventbus:3.0.0'
compile 'com.jakewharton.timber:timber:4.5.1'

compile 'com.jakewharton:butterknife:8.5.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'

}

我在构建期间遇到的错误是：

    Warning:You aren't using a compiler supported by lombok, so lombok will not work and has been disabled.
Your processor is: com.android.jack.eclipse.jdt.internal.compiler.apt.dispatch.BatchProcessingEnvImpl
Lombok supports: sun/apple javac 1.6, ECJ

Answer 1

您不能同时拥有jack和lombok，因此您需要选择更多内容。

除非你真的需要它，否则可以接受jack（现在无论如何都是announced dead），因为某些Java 8功能可以用外部库替换（即Lambda用{{3 }}）。

将lombok添加到使用Java 8的Android项目中
