如何运行使用gradle打包的项目

目标：https://github.com/davenkin/springmvc4-helloworld

使用SpringMVC编写的一个HelloWorld程序。

初学Gradle只能一步步摸索前进。

该项目对应的build.gradle

apply plugin: 'idea'
apply plugin: 'jetty'

repositories {
    mavenCentral()
}

dependencies {
    compile 'org.springframework:spring-webmvc:4.0.6.RELEASE'
    providedCompile 'javax.servlet:servlet-api:2.5'
}

task wrapper(type: Wrapper) {
    gradleVersion = '3.0'
}

测试：

如上所示，本地有Gradle环境，如果没有的话需要使用gradlew build命令

它会自动去下载gradle运行环境

由于未知的下载速度问题，最好使用梯子，下载下来如下配置也是可以的。
