Gradle学习二（Gradle构建）

初始化项目

创建文件夹

❯ mkdir basic-demo
❯ cd basic-demo

执行初始化命令

D:\study\gradle\basic-demo>gradle init
Starting a Gradle Daemon (subsequent builds will be faster)

Select type of project to generate:
  1: basic
  2: cpp-application
  3: cpp-library
  4: groovy-application
  5: groovy-library
  6: java-application
  7: java-library
  8: kotlin-application
  9: kotlin-library
  10: scala-library
Enter selection (default: basic) [1..10] 1

Select build script DSL:
  1: groovy
  2: kotlin
Enter selection (default: groovy) [1..2] 1

Project name (default: basic-demo):

5 Gradle Wrapper script for Windows
6 Gradle settings script for configuring the Gradle build

创建一个任务

准备

mkdir src
echo Hello,World! > src/myfile.txt

build.gradle

task copy(type: Copy, group: "Custom", description: "Copies sources to the dest directory") {
    from "src"
    into "dest"
}

定义一个名字叫copy的任务，把src目录下的内容复制到dest目录下!

执行任务：

D:\study\gradle\basic-demo>gradlew copy
