【问题描述】：

我将 JellyRefreshLayout 作为模块导入（用于某些更新）

检查此链接： https://github.com/allan1st/JellyRefreshLayout

但我总是收到这个 gradle build 错误：

项目等级构建：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
        classpath 'me.tatarka:gradle-retrolambda:3.2.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

应用分级：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "uk.co.imallan.jellyrefreshlayout"
        minSdkVersion 19
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile project(":jellyrefresh")
}

库模型：

repositories {
    mavenCentral()
}

apply plugin: 'com.android.library'
apply plugin: 'me.tatarka.retrolambda'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.3.0'
}

注意：我的项目 JDK 选择和默认 JDK 是： /Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home

请指教！谢谢！

【问题讨论】：

它已经是 unchecked man 了。
“离线模式”在末尾错误。使缓存无效并重新启动工作室。
我试过了，但是什么都没做。

标签： java android import module java-8

【解决方案1】：

现在解决了。

问题是：internal_impl.jar 有时不在 retrolambda 类路径中。因为以下之一：

因为依赖项可能会在第二次执行时更新。
可能是 Gradle Android 插件中的错误。

解决方案是：在同步 gradle 之前，我从 gradle 终端运行 gradle 清理和组装命令：

./gradlew clean assembleDebug

来自 Gradle 终端。
