# 打开cmd：gradle -v

• 修改maven下载源

# 在init.d 文件夹创建init.gradle 文件
allprojects {
    repositories {
        mavenLocal()
        maven { name "Alibaba" ; url "https://maven.aliyun.com/repository/public" } 
        maven { name "Bstek" ; url "https://nexus.bsdn.org/content/groups/public/" } 
        mavenCentral()
