Gradle是一種自動化建構工具,使用DSL來聲明項目設置。通過Gradle,可以對項目的依賴進行配置,並且自動下載所依賴的文件,使得構建項目的效率大大提高。
1. 安裝Gradle
下載Gradle的最新版本,並解壓,設置環境變量GRADLE_HOME,並且將%GRADLE_HOME%\bin添加到Path裡面;
2. 安裝Gradle插件
在Eclipse的Help->Eclipse Marketplace中搜索Gradle,安裝Buildship;
3. 創建Gradle項目
選擇File->New->Other->Gradle->Gradle Project,新建一個Gradle項目:
設置Gradle路徑以及Java路徑:
4. 將Project轉換成Web Project
右鍵單擊項目,選擇Properties->Project Facets,選擇Dynamic Web Module:
5. 配置Gradle
打開build.gradle文件,進行如下編輯:
/* * 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(),也可以使用mavenCentral(),不過jcenter()更好,包含了mavenCentral()。依賴關系中配置了Struts、Spring、Hibernate的文件,以及其他一些常用的文件。
點擊Gradle Executions的Run按鈕,就開始自動下載上述配置的依賴文件,是不是比以前方便多了?當然,如果已經有了這些文件,也可以依賴本地的文件。
