These are some open source tools i am using recently, just write them down.

1. Firstly, in mainland China, I need to use maven mirror.

    repositories {
        maven { url 'https://maven.aliyun.com/repository/google/' }
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url "https://s01.oss.sonatype.org/content/groups/public" }
        google()
        mavenCentral()
    }
