引入project后不能Gradle出错

[喝雪碧肚疼]

本人第一次引用github的开源项目，由于不太会，引入后build失败。删除后依然不能build，不知道哪里配置错误。
这是log：

Error:Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at http://gradle.org/docs/1.12/userguide/gradle_daemon.html
Please read below process output to find out more:
-----------------------
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

以下是project的gradle：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12.2'
}
}

allprojects {
repositories {
jcenter()
}
}

这是modules的gradle：
apply plugin: 'com.android.application'

android {
compileSdkVersion 20
buildToolsVersion '20.0.0'

defaultConfig {
applicationId "com.example.ui"
minSdkVersion 14
targetSdkVersion 20
}

buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
}

dependencies {
compile 'com.android.support:support-v4:20.+'
compile 'com.android.support:appcompat-v7:20.+'
}

已经解决，应该是分配内存不足。 解决办法： 1 定位到目录 C:\Users\<username>\.gradle 2 创建文件gradle.properties 内容：org.gradle.jvmargs=-Xmx512m 3 重启你的Android Studio项目，搞定。
