Proxy setting

　　1. git

git config --global http.proxy http://proxyuser:[email protected]:8080

2. gradle
Scenario build.gradle example:
　　　　　　repositories {
  　　 　　　　mavenCentral()
　　　　　　}

　　　　　　dependencies {
    　　　　　compile "joda-time:joda-time:2.2"
　　}
When running gradle build, it fails with Connect to https://repo1.maven.org/maven2/joda-time/joda-time/2.2/ timeout

Solution: you can put a file named gradle.properties under your project direcory (or in the Gradle home directory), and put the following content inside:
　　　　　　systemProp.https.proxyHost=yourProxyxxx
　　　　　　systemProp.https.proxyPort=xxx
　　　　　　systemProp.https.proxyUser=xxx
　　　　　　systemProp.https.proxyPassword=xxx
Notice that http doesnot work for this case ORZ...(why? #TODO)
