Question

我完全不知道发生了什么。我已尝试在SO中发布的每个解决方案，但问题仍然存在。

同步Gradle文件时，一切顺利：

Executing tasks: [:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies]

Parallel execution with configuration on demand is an incubating feature.

BUILD SUCCESSFUL

Total time: 2.906 secs

然后问题是当我点击＆＃34;播放＆＃34;按钮运行应用程序，抛出这个恼人的错误：

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
> java.lang.NullPointerException

在控制台中运行gradle build --stacktrace，我收到以下消息：

FAILURE: Build failed with an exception.

* Where:
Build file '.../project-name/app/build.gradle' line: 1

* What went wrong:
A problem occurred evaluating project ':app'.
> Failed to apply plugin [id 'com.android.application']
   > Minimum supported Gradle version is 2.14.1. Current version is 2.11. If using the gradle wrapper, try editing the distributionUrl in /Users/jozan/projects/krimturstudios/adventures/gradle/wrapper/gradle-wrapper.properties to gradle-2.14.1-all.zip

有趣的是，我已经将gradle 2.11设置为无处...它始终是2.14.1。

在我的Android Studio设置中，我检查了选项＆＃34;使用默认的gradle包装器（推荐）＆＃34;。

在我的项目设置中，我将Gradle版本设置为2.14.1。

这是我的 gradle-wrapper.properties 文件：

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip

这是我的项目 build.gradle 文件：

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath "io.realm:realm-gradle-plugin:1.2.0"
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

这是我应用的 gradle.build 文件：

apply plugin: "com.android.application"
apply plugin: "android-apt"
apply plugin: "realm-android"

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.2"

    defaultConfig {
        applicationId "..."
        minSdkVersion 17
        targetSdkVersion 24
        versionCode 1
        versionName "0.2"
    }

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

dependencies {
    // Local
    compile fileTree(include: ["*.jar"], dir: "libs")

    // Testing
    testCompile "junit:junit:4.12"

    // Android
    compile "com.android.support:appcompat-v7:24.2.1"
    compile "com.android.support:support-v4:24.2.1"

    // Butterknife
    compile "com.jakewharton:butterknife:8.4.0"
    apt "com.jakewharton:butterknife-compiler:8.4.0"
}

请任何人，这让我发疯了！

Answer 1

在cmd类型的gradlew中。它应该下载2.14版本。

Answer 2

删除并克隆我的仓库后，逐步添加每个更改，我终于解决了问题。

Gradle和Android Studio都没有造成这种情况，但 Realm ！。

我在模型类中声明了这个字段：

private RealmList<? extends Item> items;

以某种方式阻止gradle正确构建。删除允许构建和部署。

有趣的是，Realm不会给我任何错误或警告......也许是一个错误。

尝试部署应用程序时，Gradle构建失败
