【错误记录】Android Studio 编译报错 ( Error: Duplicate resources | 使用 sourceSets 配置多个 res 资源不能有重复名称的资源 )

一、报错信息

---

在 Android Studio 项目中 , 在 build.gradle 中 使用

    sourceSets {
    
    
        main {
    
    
            res.srcDirs 'src/main/res', 'src/main/res2'
        }
    }

配置 , 同时配置多个 res 目录 ;

报错信息 :

AGPBI: {
    
    "kind":"error","text":"Duplicate resources","sources":[{
    
    "file":{
    
    "description":"string/app_name","path":"Y:\\002_WorkSpace\\001_AS\\SVG\\app\\src\\main\\res\\values\\strings.xml"}},{
    
    "file":{

二、解决方案

---

在 配置了 $2$ 个 res 目录 ,'src/main/res', 'src/main/res2' ,

其中 " src/main/res2/values/string.xml " 内容为 :

<resources>
    <string name="app_name">SVG_res2</string>
    <string name="res2">res2</string>
</resources>

" src/main/res/values/string.xml " 内容为 :

<resources>
    <string name="app_name">SVG</string>
</resources>

$2$ 个目录中 , 都有 <string name="app_name"> 属性 , 必须删除一个 , 才能编译通过 , 否则会报 Error: Duplicate resources 错误 ;

将 " src/main/res2/values/string.xml " 内容 删除 app_name 属性 , 修改为 :

<resources>
    <string name="res2">res2</string>
</resources>

之后正常编译通过 ;
