我们的Android studio工程有时会存在很多共同的构建包

这里我会新建一个gradle 文件

config.gradle

ext{
android = [
applicationId : "net.huansi.loosecloth",
compileSdkVersion : 28,
minSdkVersion : 15,
targetSdkVersion : 28,
versionCode : 1,
versionName : "1.0",
support : "28.0.0"
]
def dependVersion = [
baseform : "19.6.6.1-SNAPSHOT",
retrofit : "2.2.0",
okhttp : "3.6.0",
dagger2 : "2.7",
butterknife : "8.6.0",
glide : "4.5.0",
]

var = \[  
        //base  
        appcompat\_v7              : "com.android.support:appcompat-v7:${android.support}",  
        cardview\_v7               : "com.android.support:cardview-v7:${android.support}",  
        recyclerview\_v7           : "com.android.support:recyclerview-v7:${android.support}",

        //network  
        gson                      : "com.google.code.gson:gson:2.8.2",

        glide                     : "com.github.bumptech.glide:glide:${dependVersion.glide}",  
        glide\_compiler            : "com.github.bumptech.glide:compiler:${dependVersion.glide}",  
        glide\_transformations     : "jp.wasabeef:glide-transformations:3.0.1",

        butterknife               : "com.jakewharton:butterknife:${dependVersion.butterknife}",  
        butterknife\_compiler      : "com.jakewharton:butterknife-compiler:${dependVersion.butterknife}",

        //other

        //滑动轮  
        wheelview                 : "com.contrarywind:wheelview:4.0.5",  
        //相册选择  
        picture\_selector          : "com.github.LuckSiege.PictureSelector:picture\_library:v2.2.0",  
        //dialog管理  
        material\_dialog           : "com.afollestad.material-dialogs:core:0.9.6.0",

        constraint                : "com.android.support.constraint:constraint-layout:1.1.3",  
        autofittextview           : "me.grantland:autofittextview:0.2.1"  
\]

}

然后在工程的build.gradle中引用

apply from :"config.gradle"

应用到各个module中引用
