Android Studio Gradle 错误 - preDexDebug

问题描述

我最近向我的 android studio 项目添加了一个新活动，现在当我尝试运行它时出现错误.它构建良好，但运行时出现以下错误:

I recently added a new activity to my android studio project and now I am getting an error when I try and run it. It builds fine but I get the error below when I run it:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:preDexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    /Applications/Android Studio.app/sdk/build-tools/android-4.4W/dx --dex --output /Users/davidcavanagh/joshcpdandroid/app/build/intermediates/pre-dexed/debug/classes-22ecb8c50fefe43948d87c9fee8e36a6b7d1bb5a.jar /Users/davidcavanagh/joshcpdandroid/app/build/intermediates/exploded-aar/com.android.support/support-v4/20.0.0/classes.jar
  Error Code:
    1

这是我的 build.gradle 文件

Here is my build.gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion '20.0.0'

    defaultConfig {
        applicationId "com.joshcpd.android"
        minSdkVersion 15
        targetSdkVersion 20
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:5.2.08'
    compile 'com.android.support:appcompat-v7:20.0.0'
    compile project(':libraries:zbar')
}

我已尝试删除 supportLappcompat 依赖项，但随后出现更多错误.非常感谢任何帮助.

I have tried removing the supportLappcompat dependency but then I get even more errors. Any help greatly appreciated.

推荐答案

我终于通过下载最新版本的gradle解决了这个问题.

I finally solved this issue by downloading the latest version of gradle.

我仍然经常收到这个错误，我只是通过转到文件 ----> 使缓存无效/重新启动来修复它

I still get this error every so often and I just fix it by going to File ----> Invalidate caches/restart

我发现 Android Studio 有很多问题

I find Android Studio to be very buggy
