Gradle的一些技巧和遇到的问题

./gradlew build --stacktrace > logs.txt 2>logErrors.txt
输出错误日志

gradlew assembleDebug
gradlew tinkerPatchDebug

```
# 查看构建版本
./gradlew -v
# 清除build文件夹
./gradlew clean
# 检查依赖并编译打包
./gradlew build
# 编译并安装debug包
./gradlew installDebug
# 编译并打印日志
./gradlew build --info
# 译并输出性能报告，性能报告一般在 构建工程根目录 build/reports/profile
./gradlew build --profile
# 调试模式构建并打印堆栈日志
./gradlew build --info --debug --stacktrace
# 强制更新最新依赖，清除构建并构建
./gradlew clean build --refresh-dependencies

# 编译并打Debug包
./gradlew assembleDebug
# 这个是简写 assembleDebug
./gradlew aD
# 编译并打Release的包
./gradlew assembleRelease
# 这个是简写 assembleRelease
./gradlew aR

./gradlew app:dependencies 去除重复依赖库优化
