android studio 3.0,更新html
classpath ‘com.android.tools.build:gradle:3.0.0’之後,出現報錯android
Error:All flavors must now belong to a named flavor dimension. The flavor 'flavor_name' is not assigned to a flavor dimension.
報錯的緣由:查看給出的連接地址:https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html#apply_pluginapp
The plugin now requires that all flavors belong to a named flavor dimension—even if you intend to use only a single dimension. Otherwise, you will get the following build error:
意思大體說,這個3.0的插件要求flavor dimension必需要有,哪怕只有一個維度也要聲明, flavorDimensions 是在android{}中的字段:能夠理解成維度,好比下面只聲明瞭一個渠道的維度,學習
flavorDimensions "channel" //渠道 productFlavors { qh360 { manifestPlaceholders = [UMENG_CHANNEL_VALUE: "qh360"] dimension "channel" } baidu { manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"] dimension "channel" } }
關於flavorDimensions 能夠生成多維度,好比下面的代碼gradle
// 兩個維度 flavorDimensions "isFree", "channel" productFlavors { free { // 免費和付費用isFree作標識,小米和htc爲發佈到的平臺用channel作標識,於是最後生成4 //種flavor,加上buildtype就是4*2=8種 dimension "isFree" ... } paid { dimension "isFree" ... } xiaomi{ dimension "channel" ... } htc{ dimension "channel" ... } }
其實就是在3.0插件之後,google要求必須添加這個flavorDimensions 這個字段哪怕是隻有一個維度也要寫上纔不報錯,
而後看到stackoverflow上的回答更簡單的使用以下:ui
android { defaultConfig { flavorDimensions 'default' }
或是:google
android { defaultConfig { flavorDimensions 'versionCode' }
