第三个为gradle工具自身的一些配置，如位置，发布地址等。内容如下：
#Sat May 19 19:44:18 CST 2018
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
该文件我们一般不会将它放到版本管理中
第四个为项目混淆配置文件，一般在对外发布app时为了防止应用代码被破解会使用proguard工具将项目代码进行混淆处理。
第五个为项目的属性配置文件，主要是对一些内置属性进行配置，如jvm参数等。内容如下：
# Project-wide Gradle settings.
# IDE (e.g. Android Studio) users:
# Gradle settings configured through the IDE *will override*
# any settings specified in this file.
# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/curre ... ld_environment.html
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
org.gradle.jvmargs=-Xmx1536m
# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/curre ... :decoupled_projects
# org.gradle.parallel=true
第六个为项目的脚本配置文件，主要是在gradle构建的初始化阶段告诉gradle该项目包含多少个module。内容如下：
include ':app'
第七个为项目的属性配置文件，一般为android sdk的路径，ndk的路径等。内容如下：
## This file is automatically generated by Android Studio.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file should *NOT* be checked into Version Control Systems,
# as it contains information specific to your local configuration.
#
# Location of the SDK. This is only used by Gradle.
# For customization when using a Version Control System, please read the
# header note.
sdk.dir=C\:\\Users\\Administrator\\AppData\\Local\\Android\\Sdk |
