希望自己的一些解决问题的经历可以分享给需要的各位
在运行项目的过程中，或多或少都会遇到一些编译的问题，项目跑不起来的感觉真的让人真着急，相信每一个程序员都感同身受，折腾了一天半，解决了自己项目的编译问题，迫不及待的分享给需要的那个你。
问题1：Gradle’s dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
问题描述
Gradle’s dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
Re-download dependencies and sync project (requires network)
解决方案
1.打开项目中的 gradle-wrapper.properties 文件
2.将会看到这样一行指定下载gradle的地址：distributionUrl=https://services.gradle.org/distributions/gradle-4.6-all.zip
3.将https改成http 或者 将all改成bin
原因

问题二：Connect to dl.google.com:443 no response
问题描述
Connect to dl.google.com:443 no response
解决方案
在xxx\android-studio\gradle\m2repository\com\android\tools\build\gradle找到已经下载好的版本替换一下
原因
待续
问题三：WARNING: The following project options are deprecated and have been removed:
问题描述
ERROR: Unable to resolve dependency for ‘:app@debug/compileClasspath’: Could not resolve com.android.support:appcompat-v7:28.0.0.
Show Details
Affected Modules: app
WARNING: The following project options are deprecated and have been removed:
android.enableAapt2
This property has no effect, AAPT2 is now always used.
解决方案
移除gradle.properties中android.enableAapt2=true
原因
28.0.0已经不支持AAPT2,移除相关配置即可
问题四：You have JVM property “socksProxyHost” set to “127.0.0.1”.
问题描述
This may lead to incorrect behaviour. Proxy should be set in Settings | HTTP proxy.
This JVM property is old and its usage is not recommended by Oracle.
(Note: It could have been assigned by some code dynamically.)
解决方案
重启电脑
原因
我猜测可能是因为端口冲突
问题五：Could not find builder.jar (com.android.tools.build:builder:3.1.0). Searched in the following locations:
问题描述
Could not find builder.jar (com.android.tools.build:builder:3.1.0). Searched in the following locations: https://dl.google.com/dl/android/maven2/com/android/tools/build/builder/3.1.0/builder-3.1.0.jar
其实也不针对3.1.0，任何一个版本的jar都可能出现这个问题
解决方案
原因
我猜测是代理不支持https的下载
