Gradle构建工具

1.创建主项目

打开命令行，创建目录，执行如下命令：

(base) ouyangMBP:gradle-test2 ouyang$ gradle init

Select type of project to generate:
  1: basic
  2: application
  3: library
  4: Gradle plugin
Enter selection (default: basic) [1..4] 1

Select build script DSL:
  1: Groovy
  2: Kotlin
Enter selection (default: Groovy) [1..2] 1

查看生成的目录树：

(base) ouyangMBP:gradle-test2 ouyang$ tree
.
├── build.gradle
├── gradle
│   └── wrapper
│       ├── gradle-wrapper.jar
│       └── gradle-wrapper.properties
├── gradlew
├── gradlew.bat
└── settings.gradle

其中gradle-wrapper是帮你自动设置和安装gradle的工具，同时它还提供了gradlew和gradlew.bat这两个执行文件，用来执行gradle的任务。

2.创建App项目

在项目主目录下创建目录app，然后进入app目录，如下创建app项目

(base) ouyangMBP:gradle-test2 ouyang$ mkdir app
(base) ouyangMBP:gradle-test2 ouyang$ cd app/
(base) ouyangMBP:app ouyang$ gradle init

Select type of project to generate:
  1: basic
  2: application
  3: library
  4: Gradle plugin
Enter selection (default: basic) [1..4] 2

Select implementation language:
  1: C++
  2: Groovy
  3: Java
  4: Kotlin
  5: Swift
Enter selection (default: Java) [1..5] 3

Select build script DSL:
  1: Groovy
  2: Kotlin
Enter selection (default: Groovy) [1..2] 1

Select test framework:
  1: JUnit 4
  2: TestNG
  3: Spock
  4: JUnit Jupiter
Enter selection (default: JUnit 4) [1..4] 1

Project name (default: app): 
Source package (default: app): com.test

查看app项目，生成的目录树

(base) ouyangMBP:app ouyang$ tree
.
├── build.gradle
├── gradle
│   └── wrapper
│       ├── gradle-wrapper.jar
│       └── gradle-wrapper.properties
├── gradlew
├── gradlew.bat
├── settings.gradle
└── src
    ├── main
    │   ├── java
    │   │   └── com
    │   │       └── test
    │   │           └── App.java
    │   └── resources
    └── test
        ├── java
        │   └── com
        │       └── test
        │           └── AppTest.java
        └── resources

3.修改主项目

打开settings.gradle

# 增加下面这一行
include 'app'
