Eclipse 使用 Gradle 下载 Jar 包全纪录

前言

最近想用七牛来上传图片，需要一些jar依赖包，以前都是手动下载 jar 包。gradle可以自动下载依赖 jar 包，于是折腾了一下 gradle，这儿做下记录方便初学者。如有错误，多多指正。

下载 Gradle

第一步需要下载 Gradle，配置环境变量。

• 下载地址为 http://gradle.org/gradle-download/

• 解压，把 gradle 包放到某个目录下，比如/Applications/gradle-2.10

• 把 gradle的bin 目录加到环境变量中，Mac 是编辑~/.bash_profile 
  export GRADLE_HOME=/Applications/gradle-2.10 
  export PATH=GRADLEHOME/bin:PATH

• 运行gradle -v，输出版本信息表示配置成功

Eclipse 安装插件

利用 Install new softwate -> Install, 输入插件网址 http://dist.springsource.com/release/TOOLS/gradle，安装完需要重启 Eclipse。

Eclipse 将项目转为 Gradle

注意 Gradle 默认的项目结构中 java 源代码放在src/main/java目录。

在 Java 项目根目录新建一个build.gradle文件，笔者使用了最简单的功能，所以build.gradle就短短几行

<code class="hljs matlab has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">apply plugin: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'java'</span>repositories <span class="hljs-cell" style="box-sizing: border-box;">{      mavenCentral()  }</span>  dependencies <span class="hljs-cell" style="box-sizing: border-box;">{      compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'com.qiniu:qiniu-java-sdk:7.0.+'</span>}</span> </code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li></ul>

然后右键项目，Configure -> Convert to Gradle Project，完成后会发现项目左上角有个 G 的图标

利用Gradle下载依赖 Jar 包

注意在build.gradle文件里的compile 'com.qiniu:qiniu-java-sdk:7.0.+'就是我们需要的 jar 包。待会 gradle 就会根据该配置下载jar 包，gradle 还会分析其中的依赖关系将所有需要的包一并下载。 
项目右键，点击 Gradle -> Refresh All

可以看到控制台输出如下信息，表示正在下载jar 包。从中也可以看出，虽然我们只写了一个qiniu:qiniu Jar 包，但是它依赖于okhttp、okio等，gradle 会帮助我们一并下载。

可以看到现在项目多了我们需要的 Jar 包。

命令行方法下载 jar 包

我们也可以利用命令行方法，而不是 Eclipse 鼠标点击的方法。

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">apply plugin: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'java'</span>repositories {      mavenCentral()  }  dependencies {      compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'org.jsoup:jsoup:1.7.2'</span>}  task downloadJars(type: Copy) {  <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">from</span> configurations.runtime  <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">into</span> <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'libs'</span> <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// 目标位置</span>}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li><li style="box-sizing: border-box; padding: 0px 5px;">12</li><li style="box-sizing: border-box; padding: 0px 5px;">13</li><li style="box-sizing: border-box; padding: 0px 5px;">14</li></ul>

如上所示，在build.gradle里面定义一个 task，名称为 downloadJars，libs目录会存放下载的jar包。

然后在命令行中进行如下操作：

• cd到java项目的根目录（这一步要牢记，不然 gradle 不知道是哪个项目）

• 运行 gradle downloadJars

运行结果如下图，

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">TomChens-MBP:ParseNewsData tomchen$ gradle downloadJars:downloadJarsDownload https://repo1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.maven</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.org</span>/maven2/org/jsoup/jsoup/<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1.7</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.2</span>/jsoup-<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1.7</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.2</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.pom</span>Download https://repo1<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.maven</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.org</span>/maven2/org/jsoup/jsoup/<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1.7</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.2</span>/jsoup-<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1.7</span><span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">.2</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.jar</span>BUILD SUCCESSFULTotal time: <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">7.637</span> secs</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li></ul>

运行

想让 java 项目运行需要利用application插件，设置main class文件位置，在 gradle 里面加上下面两行。

<code class="hljs bash has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">apply plugin: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'application'</span>mainClassName = <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'biz.ArticleItemBiz'</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

依赖包的地址

大家肯定有疑惑，compile 'com.qiniu:qiniu-java-sdk:7.0.+'后面的一堆字符到哪儿找。

• 一般jar 包的官方都会提供，比如七牛官方就提供了Maven和Gradle 配置:
