Android Studio，Gradle 错误。 Prolog 中不允许的内容

Question

我一直在将 Android Studio 与 Ubuntu 13.10 结合使用，没问题。我决定更新到 14.04，现在我无法让 Android Studio 工作。 Gradle 无法构建并一直提示错误:Prolog 中不允许内容。我所做的只是从头开始创建一个新项目。

1. Ubuntu 14.04 是从新删除的分区安装的
2. 使用 Android Studio v5.7，虽然我也尝试过 v4.6
3. 我安装了 Oracle JDK 并相应地设置了 $JAVA_HOME 路径
4. 我已经安装了 gradle

5. 我已确保 build.gradle 具有:

   依赖关系{ 类路径 'com.android.tools.build:gradle:0.9.+'

6. 我已经尝试过 gradle build clean。它也出错了。

7. 我尝试过在 Android Studio 中清理/重建项目。出错了。

应用构建.gradle:

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.3"

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.+'
}

全局构建等级:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.9.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

您可以尝试清除您的 gradle 缓存:gradle clean --refresh-dependencies 并删除 ~/.gradle/caches 的内容。应该有帮助。
