[Java教程]Eclipse中使用Gradle构建Java Web项目


Gradle是一种自动化建构工具,使用DSL来声明项目设置。通过Gradle,可以对项目的依赖进行配置,并且自动下载所依赖的文件,使得构建项目的效率大大提高。

1. 安装Gradle

下载Gradle的最新版本,并解压,设置环境变量GRADLE_HOME,并且将%GRADLE_HOME%\bin添加到Path里面;

2. 安装Gradle插件

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

3. 创建Gradle项目

选择File->New->Other->Gradle->Gradle Project,新建一个Gradle项目:

设置Gradle路径以及Java路径:

4. 将Project转换成Web Project

右键单击项目,选择Properties->Project Facets,选择Dynamic Web Module:

5.  配置Gradle

打开build.gradle文件,进行如下编辑:

/* * 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 Javaapply plugin: 'java'// In this section you declare where to find the dependencies of your projectrepositories {  // 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 codedependencies {  // 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'}

仓库使用了jcenter(),也可以使用mavenCentral(),不过jcenter()更好,包含了mavenCentral()。依赖关系中配置了Struts、Spring、Hibernate的文件,以及其他一些常用的文件。

点击Gradle Executions的Run按钮,就开始自动下载上述配置的依赖文件,是不是比以前方便多了?当然,如果已经有了这些文件,也可以依赖本地的文件。
