# 查看当前工程的依赖

./gradlew app:dependencies

# 检索依赖库
./gradlew app:dependencies | grep CompileClasspath

# windows 没有 grep 命令
./gradlew app:dependencies | findstr "CompileClasspath"

# 将检索到的依赖分组找到 比如 multiDebugCompileClasspath 就是 multi 渠道分发的开发编译依赖
./gradlew app:dependencies --configuration multiDebugCompileClasspath

# 一般编译时的依赖库，不是固定配置方式，建议检索后尝试
./gradlew app:dependencies --configuration compile

# 一般运行时的依赖库，不是固定配置方式，建议检索后尝试
./gradlew app:dependencies --configuration runtime

./gradlew build --daemon

./gradlew build --parallel --parallel-threads=N

./gradlew build --offline

./gradlew build --configure-on-demand

Configuration on demand is not supported by the current version of the Android Gradle plugin since you are using Gradle version 4.6 or above.
Suggestion: disable configuration on demand by setting org.gradle.configureondemand=false in your gradle.properties file or use a Gradle version less than 4.6.
