Android-Gradle从命令行构建针对多种口味的APK

Question

我想同时创建多个apk。配置构建版本指南位于此处：https://developer.android.com/studio/build/build-variants

示例如下：

buildTypes {
  ...
}

flavorDimensions "api", "mode"
productFlavors {
  demo { dimension "mode" }
  full { dimension "mode" }
  minApi24 { dimension "api" }
  minApi23 { dimension "api" }
  minApi21 { dimension "api" }
}

assembleMinApi21 => MinApi21 [Full，Demo] [Debug，Release]->预期

assembleMinApi21Demo => MinApi21Demo [Debug，Release]->预期2个apk，仅生成调试版本

为什么assembleMinApi21Demo无法生成minApi21-demo-release.apk？
