Maven 學習筆記——將普通的Java專案轉換成Maven專案（3）

Maven筆記Java

         將一個普通的java專案轉換成Maven專案並不是一個很大的任務，僅僅只需要下面的幾步就能將轉換成功。下面我是用一個簡單的Selenium測試小demon作為例子來說的。

  1. 移調專案中所有關聯的Libraries
  2. 將Selenium專案轉換成Maven專案
  3. 增加Maven依賴庫到專案中
  4. 建立Maven的測試資料夾架構

Step1：移調專案中所有關聯的Libraries

      選中你需要轉換的Project:Build Path > Configure Build Path

1

 

Step2： 將Selenium專案轉換成Maven專案

     1) 右鍵需轉換的專案，Configure > Convert Maven Project

     2) 要求填入Group ID和Artifact ID，這個不需要改變，用預設專案提供的

2

 

   3) 轉換成功後，該專案在Eclipse中的結構變成下面這樣

 

      old             new

                    沒轉換前的結構                                                                               轉換後的結構

 

Step3：增加Maven依賴庫到專案中

        現在我們就需要將專案中所需要的依賴包加到本地中心源中，我就針對這個專案來說，我們知道我們現在缺少Selenium jar包，junit jar包等等。

1） 到 http://www.mvnrepository.com/ 上面查詢Selenium

2） 點選Selenium Java

3

3） 選擇你所需要使用的Selenium的版本

4

4） 關於Selenium在Maven中資訊就會顯示出來，然後將這些資訊加到pom.xml中

5

5) 將Selenium的dependency的資訊加到pom.xml，可以在Dependencies以流程的方式新增進去，儲存，這個時候會下載相關的依賴包到本地源中心中。（需要一點時間，有任何問題，可以參考之前Maven（1）中提到，解決問題）

67

6）直接在pom.xml中將查詢到的資訊拷貝到xml檔案中，儲存。

8

7）等待依賴包被下載完後，所有的錯誤就會解決

Step4 建立Maven的測試資料夾架構

接下來就是檢驗真理的時候，看這個轉換的Selenium專案能否跑起來，選擇pom.xml > Run As > Maven Test 結果-----------測試用例沒有被執行，這是為什麼呢？仔細看看log，發現Maven預設是在\src\main\resource這個路徑下找的原始碼資源，測試原始碼是在\src\test\resources 。

輸出結果為：

[INFO] Scanning for projects...

[INFO] ------------------------------------------------------------------------

那麼現在的目的就是怎麼自定義Maven的目錄結構？

下面這個程式碼是把原始碼設定成src目錄下，把測試的原始碼放在src/test下面，這樣修改後就解決剛才的問題了，測試就跑起來了。這樣一個Selenium專案就轉換成Maven專案了。

<build>
    <sourceDirectory>src/</sourceDirectory>
 
    <testSourceDirectory>src/test</testSourceDirectory>
</build>

成功後的輸出結果：

PS；附一張Maven的標準目錄結構：

WHOOOOSHHHHHHHHHHHH…………

Blimey what was that?

That was your life mate

Oh, I was not quite ready. Can I have another go?

Sorry mate, only one per person.
