Follow Fang!: 整合 GitLab Private Repository with Jenkins and Nexus Repository

如果還不知道如何使用Webhook可以先至『GitLab 透過 Webhook 連動 Jenkins』查看
目標：代碼提交時，透過Jenkins自動處理上傳的代碼並發布到Maven Repository

記得要先在Maven Project的pom.xml加入<distributionManagement>和maven-compiler-plugin，下方是示範的pom.xml

先透過SSH連線到Jenkins，將jenkins的使用者~/.m2./setting.xml配置好，範例setting.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <servers>
      <server>
        <id>test</id>
        <username>username</username>
        <password>password</password>
      </server>
    </servers>
</settings>

<repository>：Release，供正式環境使用

<snapshotRepository>：Snapshot，供開發及測試

先至Jenkins點擊新增建置 Maven 2 或 3 專案
