无法删除旧的javaCompile操作,可能是类名已更改

Question

我正在学习RxJava.为此,我在RxJava上关注了droidcon谈话视频.教练为他正在使用的项目提供了回购链接.当我尝试在我的机器上构建项目时,我克隆了repo.我收到这个错误

错误:无法删除旧的javaCompile操作,可能是类名已更改？请提交错误报告,告知您正在使用的gradle版本.

这是gradle.build文件

    buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath 'me.tatarka:gradle-retrolambda:2.5.0'
    }
}

repositories {
    mavenCentral()
    maven { url "https://github.com/alter-ego/advanced-android-logger/raw/develop/releases/" }
}

apply plugin: 'retrolambda'
apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "25.0.0"

    defaultConfig {
        applicationId "com.packtpub.apps.rxjava_essentials"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        jackOptions {
            enabled true
        }
    }

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

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    lintOptions {
        disable 'InvalidPackage'
        abortOnError false
    }

    packagingOptions {
        exclude 'META-INF/services/javax.annotation.processing.Processor'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:23.1.1'
    compile "com.android.support:appcompat-v7:23.1.1"
    compile 'com.android.support:recyclerview-v7:23.1.1'

    compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
    compile 'com.squareup.okhttp:okhttp:2.0.0'

    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.3'

}

知道如何解决这个问题？

Answer 1

问题来自RetroLambda插件(参见此链接中的第108行).

我认为升级插件版本可以解决您的问题:

classpath 'me.tatarka:gradle-retrolambda:3.6.1'

在 app/build.gradle 上尝试这个github
