第一種方式視覺化的：使用eclipse建立多模組專案示例

新建子專案

• 按嚮導新建專案gradleFirst
  
  
• 按嚮導新建專案gradleSecond(過程略)
• 按嚮導新建專案gradleParent(過程略)

完整的專案列表結構如下

可以手工刪除gradleParent中不必要的檔案

配置

修改gradleParent的相關配置

修改settings.gradle

rootProject.name = 'gradleParent'

include   ':gradleFirst', ':gradleSecond'
project(':gradleFirst'
 
).projectDir = new File(settingsDir, '../gradleFirst')
project(':gradleSecond').projectDir = new File(settingsDir, '../gradleSecond')

修改build.gradle

apply plugin: 'java'
apply plugin: 'eclipse'

repositories {
    jcenter()
}

dependencies {   

    testCompile 'junit:junit:4.12'     
}

dependencies {
    compile project(':gradleFirst'
 
)
    compile project(':gradleSecond')
}

檢視結果

開啟命令列，進入gradleParent目錄，看看有哪些變化

E:\eclipseWS\gradleWS\gradleParent>gradle project

> Task :projects

------------------------------------------------------------
Root project
------------------------------------------------------------

Root project 'gradleParent'
 

+--- Project ':gradleFirst'
\--- Project ':gradleSecond'

To see a list of the tasks of a project, run gradle <project-path>:tasks
For example, try running gradle :gradleFirst:tasks

E:\eclipseWS\gradleWS\gradleParent>

構建

第二種方式：控制檯建立專案然後匯入

專案存放在E:\eclipseWS\gradleWS目錄下，在此專案中建立一個子專案之間的呼叫關係

建立專案總目錄

開啟cmd，進入E:\eclipseWS\gradleWS目錄

C:\Users\Administrator>cd /d E:\eclipseWS\gradleWS

E:\eclipseWS\gradleWS>

E:\eclipseWS\gradleWS>mkdir gradleMain

進入專案主目錄並初始化

E:\eclipseWS\gradleWS\gradleMain>gradle init

BUILD SUCCESSFUL in 2s
2 actionable tasks: 2 executed
E:\eclipseWS\gradleWS\gradleMain>tree /f
資料夾 PATH 列表
卷序列號為 0004-26A4

            gradle-wrapper.properties


E:\eclipseWS\gradleWS\gradleMain>

建立多模組

建立使用的目錄，比如建立三個模組，分別叫做firstModule、secondModule、thirdModule。分別建立main、test、resources

E:\eclipseWS\gradleWS\gradleMain>mkdir firstModule\src\main\java
E:\eclipseWS\gradleWS\gradleMain>mkdir firstModule\src\main\resources
E:\eclipseWS\gradleWS\gradleMain>mkdir firstModule\src\test\java
E:\eclipseWS\gradleWS\gradleMain>mkdir firstModule\src\test\resources
E:\eclipseWS\gradleWS\gradleMain>
E:\eclipseWS\gradleWS\gradleMain>mkdir secondModule\src\main\java
E:\eclipseWS\gradleWS\gradleMain>mkdir secondModule\src\main\resources
E:\eclipseWS\gradleWS\gradleMain>mkdir secondModule\src\test\java
E:\eclipseWS\gradleWS\gradleMain>mkdir secondModule\src\test\resources
E:\eclipseWS\gradleWS\gradleMain>
E:\eclipseWS\gradleWS\gradleMain>mkdir thirdModule\src\main\java
E:\eclipseWS\gradleWS\gradleMain>mkdir thirdModule\src\main\resources
E:\eclipseWS\gradleWS\gradleMain>mkdir thirdModule\src\test\java
E:\eclipseWS\gradleWS\gradleMain>mkdir thirdModule\src\test\resources

配置

修改gradleMain目錄裡的settings.gradle

include 'firstModule','secondModule','thirdModule'

修改gradleMain目錄裡的buid.gradle

// 所有子專案的通用配置
subprojects {
    apply plugin: 'java'
    apply plugin: 'eclipse'

    version = '1.0'

    // JVM 版本號要求
    sourceCompatibility = 1.8
    targetCompatibility = 1.8

    // java編譯的時候預設狀態下會因為中文字元而失敗
    [compileJava,compileTestJava,javadoc]*.options*.encoding = 'UTF-8'

    //定義版本號
    ext {

    }

    repositories {
        mavenCentral()
    }

    jar {
        manifest {
            attributes("Implementation-Title": "Gradle")
        }
    }

    configurations {
        // 所有需要忽略的包定義在此
        all*.exclude group: 'commons-httpclient'
        all*.exclude group: 'commons-logging'
        all*.exclude group: 'commons-beanutils', module: 'commons-beanutils'
    }

    dependencies {
        // 通用依賴

        // 測試依賴
        testCompile(
                "junit:junit:4.12"
        )
    }
}

分別修改模組的build.gradle

firstModule

archivesBaseName = 'firstModule'

secondModule

archivesBaseName = 'secondModule'
archivesBaseName = 'secondModule'
project.dependencies {
    compile(
            project(':firstModule'),
    )

    testCompile(
            project(':firstModule').sourceSets.test.output,
    )
}

thirdModule

archivesBaseName = 'thirdModule'

編譯

E:\eclipseWS\gradleWS\gradleMain>gradle -i build

E:\eclipseWS\gradleWS\gradleMain>gradle project

> Task :projects

------------------------------------------------------------
Root project
------------------------------------------------------------

Root project 'gradleMain'
+--- Project ':firstModule'
+--- Project ':secondModule'
\--- Project ':thirdModule'

To see a list of the tasks of a project, run gradle <project-path>:tasks

匯入工程

import->gradle->existing gradle project

分別在firstModule和secondModule中新增程式碼
