## Gradle插件

### [pgyer_dingtalk](plugins/pgyer_dingtalk)
一键打包上传到蒲公英，并发送钉钉消息到群，极大地提升分发包的效率

**特性：**
1. 打包完毕后，上传包到蒲公英
2. 发消息到钉钉，并支持@人
3. 支持配合Jenkins，支持按包类型、分支、代理、@人及32位和64位等功能


**使用：**
```gradle
apply plugin: 'dingPgyer'
dingPgyerConfig {
    pgyerApiKey = "xxx" // 蒲公英ApiKey
    apiToken = "xxx" // 钉钉群机器人toekn
    atMobiles = ['135xxx','136xxx'] // 群@人的手机号
    enableByVariant = { variantName -> // 对哪些flavor开启
        variantName.toLowerCase().contains("dev-preview") || variantName.toLowerCase().contains("product-release")
    }
    changeLog = "${getGitLog(5)}" // build log，获取前5条git log
}
/**
 * 获取git log
 * @param pre 多少条git log
 * @return
 */
private String getGitLog(int pre) {
    def diffLog = new StringBuffer()
    def err = new StringBuffer()
    def workspaceFile = rootDir

    def gitChangeLogScript = new StringBuilder()
    gitChangeLogScript.append("git log --no-merges --pretty=format:\"%s\" -${pre}")
    println(gitChangeLogScript)
    def changeLogProc = gitChangeLogScript.toString().execute(null, workspaceFile)
    changeLogProc.waitForProcessOutput(diffLog, err)

    def diffLogStr = diffLog.toString()
    diffLogStr = diffLogStr.replaceAll("\"", "")
    diffLogStr = diffLogStr.replaceAll("\n", "\n\n > ")

    if (diffLogStr.length() > 1000) {
        diffLogStr = diffLogStr.substring(0, 999)
    }
    return diffLogStr
}
```

### [module_dependency_switch](plugins/switch_module_dependency)
组件化过程中，module和aar切换

配置`module_dependency.json`：
```
{
    "useModule": true,
    "module_name": "Modularization1",
    "module_dir": "Modularization1",
    "module_group": "me.hacket:Modularization1"
}
```
- useModule true表示module依赖，false表示aar依赖
- module_name module的name
- module_dir module路径
- module_group module对应的远端aar的group和artifactId
