问题描述
我正在使用此代码
i was using this code
applicationVariants.all { variant ->
variant.outputs.each { output ->
def SEP = "_"
def flavor = variant.productFlavors[0].name
def buildType =
variant.variantData.variantConfiguration.buildType.name
def version = variant.versionName
def date = new Date()
def formattedDate = date.format('ddMMyy_HHmm')
def newApkName = PROJECT_NAME + SEP + flavor + SEP + buildType + SEP + version + SEP + formattedDate + ".apk"
def file = new File(newApkName)
output.outputFile = file
}
}
在我构建新的apk时更改apk文件的名称,但是由于我使用的是 Android Studio 3.0 Canary 2 ,因此会出现以下错误:
无法设置只读属性'outputFile'的值....
to change the name of apk file when i build new apk, but since i use the Android Studio 3.0 Canary 2 this error appear:
Cannot set the value of read-only property 'outputFile'....
推荐答案
作为 Android插件3.0迁移指南建议:
- 使用
all()
代替each()
- 如果仅更改文件名(这是您的情况),请使用
outputFileName
而不是output.outputFile
- Use
all()
instead ofeach()
- Use
outputFileName
instead ofoutput.outputFile
if you change only file name (that is your case)
指南中的示例:
// If you use each() to iterate through the variant objects,
// you need to start using all(). That's because each() iterates
// through only the objects that already exist during configuration time—
// but those object don't exist at configuration time with the new model.
// However, all() adapts to the new model by picking up object as they are
// added during execution.
android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "${variant.name}-${variant.versionName}.apk"
}
}
