Eclipse中使用Gradle構建Java Web項目

Gradle是一種自動化建構工具,使用DSL來聲明項目設置。經過Gradle,能夠對項目的依賴進行配置,而且自動下載所依賴的文件,使得構建項目的效率大大提升。html

1. 安裝Gradlejava

下載Gradle的最新版本,並解壓,設置環境變量GRADLE_HOME,而且將%GRADLE_HOME%\bin添加到Path裏面;web

2. 安裝Gradle插件spring

在Eclipse的Help->Eclipse Marketplace中搜索Gradle,安裝Buildship;apache

3. 建立Gradle項目json

選擇File->New->Other->Gradle->Gradle Project,新建一個Gradle項目:api

設置Gradle路徑以及Java路徑:app

4. 將Project轉換成Web Projectmaven

右鍵單擊項目,選擇Properties->Project Facets,選擇Dynamic Web Module:ide

5.  配置Gradle

打開build.gradle文件,進行以下編輯:

/*
 * This build file was auto generated by running the Gradle 'init' task
 * by 'simon' at '16-11-17 涓嬪崍2:49' with Gradle 3.2
 *
 * This generated file contains a sample Java project to get you started.
 * For more details take a look at the Java Quickstart chapter in the Gradle
 * user guide available at https://docs.gradle.org/3.2/userguide/tutorial_java_projects.html
 */

// Apply the java plugin to add support for Java
apply plugin: 'java'

// In this section you declare where to find the dependencies of your project
repositories {
    // Use 'jcenter' for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
}

// In this section you declare the dependencies for your production and test code
dependencies {
    // struts library
    compile group: 'org.apache.struts', name: 'struts2-core', version: '2.3.24.1'
    compile 'org.apache.struts:struts2-spring-plugin:2.3.24.1'
    compile 'org.apache.struts:struts2-json-plugin:2.3.24.1'
 
    // spring library
    compile group: 'org.springframework', name: 'spring-core', version: '4.2.3.RELEASE'
    compile group: 'org.springframework', name: 'spring-web', version: '4.2.3.RELEASE'
    compile group: 'org.springframework', name: 'spring-orm', version: '4.2.3.RELEASE'
    compile group: 'org.springframework', name: 'spring-aop', version: '4.2.3.RELEASE'
    compile group: 'org.springframework', name: 'spring-aspects', version: '4.2.3.RELEASE'
    compile group: 'org.springframework', name: 'spring-jdbc', version: '4.2.3.RELEASE'
     
    // hibernate library  
    compile group: 'org.hibernate', name: 'hibernate-core', version: '5.0.1.Final'
     
    // common library
    compile 'org.slf4j:slf4j-api:1.7.13'
    testCompile 'junit:junit:4.12'

}

倉庫使用了jcenter(),也能夠使用mavenCentral(),不過jcenter()更好,包含了mavenCentral()。依賴關係中配置了Struts、Spring、Hibernate的文件,以及其餘一些經常使用的文件。

點擊Gradle Executions的Run按鈕,就開始自動下載上述配置的依賴文件,是否是比之前方便多了?固然,若是已經有了這些文件,也能夠依賴本地的文件。
