不知道发生了什么。大约一个小时前，我刚刚在Ubuntu 15.10上将Android Studio从1.5.1版本更新到2.0版本。
似乎找不到Gradle或者Gradle有问题。找出Gradle版本并安装最新版本是有意义的，但安卓工作室似乎在线获取了Gradle版本，并使用项目级Gradle构建文件中的依赖项来完成
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
classpath 'com.google.gms:google-services:2.1.0-alpha5'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
我向谷歌提交了一份Bug报告。老实说，我不知道为什么会发生这种事。
我尝试过"使缓存无效/重新启动"-没有帮助。
我在这个构建文件中尝试了以下版本的Gradle：
classpath 'com.android.tools.build:gradle:1.5.0'
classpath 'com.android.tools.build:gradle:1.5.1'
classpath 'com.android.tools.build:gradle:2.0.0'
classpath 'com.android.tools.build:gradle:2.1.0'
这些都不起作用。每个都有相同的错误。不知道为什么。错误如下：
8:41:26 AM Gradle sync started
8:41:26 AM Gradle sync failed: org.gradle.internal.SystemProperties.getInstance()Lorg/gradle/internal/SystemProperties;
Consult IDE log for more details (Help | Show Log)
8:42:32 AM NoClassDefFoundError: Could not initialize class org.gradle.StartParameter
- 上午8:41:26-发生在开机时
- 上午8:42:32-发生在"清洁项目"one_answers"重建项目"
提前谢谢。

更新-已修复
我删除了所有的android工作室文件，项目文件（我在Git上有所有的东西）并重新安装。
我仍然有问题，但这只是因为我忘记删除旧的渐变文件，如这里的答案所示。
不要更新到2.0 YET
这太令人沮丧了。现在虚拟设备出现问题。"无法在模拟器中启动AVD"。不要像我一样，在软件发布的那天就安装它。等几周！
这对我从gradle转到build.gradle很有效。脚本
android {
compileSdkVersion 23
buildToolsVersion "23.0.0"
defaultConfig {
applicationId "CHANGE THIS XXXXXXX OWN APP ID"
minSdkVersion 15
targetSdkVersion 23
versionCode 1

}
