Gradle 为每个子项目调用不同的任务

Question

我有以下设置：

项目

• 春季启动应用程序
• 打包到 jar 中的 java 类
• 安卓项目
  • android项目的app模块

我正在尝试设置 gradle build，以便获得可运行的 spring boot jar 应用程序、安装在本地 maven repo 中的 java jar 库和 android 的 apk 文件。

• 要获取 apk 文件，我需要运行 assembleDebug 任务
• 要发布 java 库，我需要运行发布任务
• 要获得 spring 可执行文件，我需要运行 compileJave 任务

问题是在顶级根gradel.build 文件上运行什么任务来完成不同的任务？

根等级：

allprojects {
    task hello << { task -> println "I'm $task.project.name" }
}
subprojects {
    repositories {
        mavenCentral()
        jcenter()
    }
}

Spring Boot 分级：

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

defaultTasks 'clean', 'build'

buildscript {
    ext {
            springBootVersion = '1.5.1.RELEASE'
        }
        repositories {
            mavenCentral()
        }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-            plugin:${springBootVersion}")
    }
}

jar {
    baseName = 'demo'
    version = '0.0.1-SNAPSHOT'
}

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('io.jsonwebtoken:jjwt:0.7.0')
    compile('mysql:mysql-connector-java:6.0.5')

    testCompile('org.springframework.boot:spring-boot-starter-test')
}

Java Proj 毕业：

jar {
    baseName = 'commonobjects'
    version = "0.0.1-SNAPSHOT"
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

Android Proj 分级：

buildscript {
    repositories {
            jcenter()
        mavenCentral()
        }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
    }
}

Android 应用分级：

def ANDROID_SUPPORT_DEPENDENCY_VERSION = '25.1.0'
def DAGGER_DEPENDENCY_VERSION = '2.8'
def OK_HTTP_DEPENDENCY_VERSION = '3.5.0'
def RETROFIT_DEPENDENCY_VERSION = '2.1.0'
def RETROFIT_JACKSON_DEPENDENCY_VERSION = '2.1.0'
def BUTTER_KNIFE_DEPENDENCY_VERSION = '8.5.1'

def GREEN_ROBOT_EVENT_BUS_DEPENDENCY_VERSION = '3.0.0'

def RX_ANDROID_JAVA_DEPENDENCY_VERSION = '2.0.1'

defaultTasks 'clean', 'assembleDebug'

    repositories {
       mavenCentral()
       jcenter()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }

您可以简单地创建依赖于三个不同任务的任务。子项目之间也可能存在依赖关系：

task myAllTask {
}

myAllTask.dependsOn assembleDebug, publish, compileJava

从子项目运行任务：

myAllTask.dependsOn ':bootProj:assembleDebug', ':javaProj:publish', ':androidProj:compileJava
