Failed to resolve: com.github.***

问题：同步依赖包后报错Failed to resolve: com.github.GinRyan:NTabLayout:0.3.4

解决：maven放错位置了

方法：

gradle 7.0之前

在project: build.gradle中加入

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://jitpack.io"
        }
    }
}

注意：maven {url "https://jitpack.io"} 是加在allprojects中的

gradle 7.0 之后
如果用上面的方法会报
Build was configured to prefer settings repositories over project repositori的错误

不用配置project: build.gradle
在 setting.gradle(Project settings) 中增加maven {url "https://jitpack.io"}

repositories {
    google()
    mavenCentral()
    jcenter() // Warning: this repository is going to shut down soon
    repositories {
        maven { url "https://jitpack.io" }
    }
}
