1.從Kettle官網下載原始碼，本文使用的是pentaho-kettle-8.2.0.0-R

下載地址：https://codeload.github.com/pentaho/pentaho-kettle/zip/8.2.0.0-R

2.開啟eclipse,選擇一個新的工作空間，然後設定maven的資訊，settings.xml使用官方提供的配置檔案點選下載。下載可以根據需要設定自己本地倉庫的儲存路徑。

    因為為引入kettle專案原始碼的時候，會去預設的maven倉庫地址下載專案構建所需的依賴，但這些依賴只在Kettle官方的倉庫有，所以先配置好kettle的maven倉庫地址。

3.引入已存在的maven專案，將解壓後的kettle原始碼引入工作空間，如下圖所示選擇所有的專案

4.修改pom.xml中swt版本資訊，官方的原始碼在linux系統中開發的，若在windows系統或其他系統中開發時需要更換為相應的swt版本，本文在在windows環境中開發。

工作空間全文搜尋“<artifactId>org.eclipse.swt.gtk.linux.x86_64</artifactId>”更改為“ <artifactId>org.eclipse.swt.win32.win32.x86_64</artifactId>”

修改前

修改後

5.配置maven的Lifecycle Mappings
專案匯入會存在很多以下錯誤，需要配置Lifecycle Mappings解決此問題

解決方法如下圖：

lifecycle-mapping-metadata.xml檔案內容：

6.將pentaho-kettle-8.2.0.0-R\assemblies\static\src\main\resources\ui下的檔案複製一下貼上到pentaho-kettle-8.2.0.0-R\ui\src\main\resources\ui資料夾下

7.執行maven clean install,然後執行org.pentaho.di.ui.spoon.Spoon
