10. 在eclipse 工具欄中debug，run中已經有了相應的launch配置。至此kettle開發除錯環境初步搭建完成。

1.2. 編譯原始碼
將專案載入到eclipse
將kettle專案拷貝到eclipse的workspace目錄下，在eclipse中新建java project，專案名稱和你拷貝過來的kettle資料夾名稱一致

專案匯入到eclipse中會出現一個錯誤，如下圖，將這個檔案的原始碼全部註釋掉

編譯
開啟build.xml, 在右邊的。Outline 點選kettle->run as ->ant build

第一次編譯的時候需要從網上下載幾個檔案，放在C:\Documents and Settings\Administrator\.subfloor，網路不好的話下載會比較慢，也可以直接檔案放在C:\Documents and Settings\Administrator\下。編譯完成後將bin目錄下的.bat檔案拷貝到Kettle目錄下點選Spoon.bat執行，執行成功代表編譯已近通過
用原始碼執行Spoon
Kettle原始碼工程本身可能是在linux64位機器上除錯的，swt配置是linux64的庫，所有在執行原始碼前需要修改成win32的swt，步驟如下：工程à屬性àJava Build Pathàlibrariesàadd jars

然後將linux64的SWT庫刪除

最後開啟src-uiàorg.pentaho.di.ui.spoonàSpoon.java， Run As àjava application
二．原始碼分析
2.1. 修改kettle介面
修改初始化介面
開啟package org.pentaho.di.ui.spoon的Spoon.Java，找到main函式，該main函式為Spoon工具的入口，找到如下語句

Splash splash = new Splash(display);

該語句為spoon初始化顯示的介面，跳到定義Splash.java，下面函式

canvas.addPaintListener(new PaintListener() {
publicvoid paintControl(PaintEvent e) {
String versionText = BaseMessages.getString(PKG, "SplashDialog.Version") + " " + Const.VERSION; //$NON-NLS-1$ //$NON-NLS-2$

StringBuilder sb = new StringBuilder();
String line = null;

try {
BufferedReader reader = new BufferedReader(newInputStreamReader(Splash.class.getClassLoader().getResourceAsStream("org/pentaho/di/ui/core/dialog/license/license.txt")));//$NON-NLS-1$

while((line = reader.readLine()) != null) {
sb.append(line + System.getProperty("line.separator")); //$NON-NLS-1$
}
} catch (Exception ex) {
sb.append(""); //$NON-NLS-1$
Log.warn(BaseMessages.getString(PKG, "SplashDialog.LicenseTextNotFound")); //$NON-NLS-1$
}

String licenseText = sb.toString();
e.gc.drawImage(kettle_image, 0, 0);

// If this is a Milestone or RC release, warn the user
if (Const.RELEASE.equals(Const.ReleaseType.MILESTONE)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.DeveloperRelease") + " - " + versionText; //$NON-NLS-1$ //$NON-NLS-2$
drawVersionWarning(e);
} elseif (Const.RELEASE.equals(Const.ReleaseType.RELEASE_CANDIDATE)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.ReleaseCandidate") + " - " + versionText; //$NON-NLS-1$//$NON-NLS-2$
}
elseif (Const.RELEASE.equals(Const.ReleaseType.PREVIEW)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.PreviewRelease") + " - " + versionText; //$NON-NLS-1$//$NON-NLS-2$
}
elseif (Const.RELEASE.equals(Const.ReleaseType.GA)) {
versionText = BaseMessages.getString(PKG, "SplashDialog.GA") + " - " + versionText; //$NON-NLS-1$//$NON-NLS-2$
}

Font verFont = new Font(e.display, "Helvetica", 11, SWT.BOLD); //$NON-NLS-1$
e.gc.setFont(verFont);
e.gc.drawText(versionText, 290, 205, true);

// try using the desired font size for the license text
int fontSize = 8;
Font licFont = new Font(e.display, "Helvetica", fontSize, SWT.NORMAL); //$NON-NLS-1$
e.gc.setFont(licFont);

// if the text will not fit the allowed space
while (!willLicenseTextFit(licenseText, e.gc)) {
fontSize--;
licFont = new Font(e.display, "Helvetica", fontSize, SWT.NORMAL); //$NON-NLS-1$
e.gc.setFont(licFont); 
}

e.gc.drawText(licenseText, 290, 290, true);
}
});

1. 修改背景圖片
找到ui/image/下面的kettle_splash.png，替換該圖片
2. 修改版本資訊
找到e.gc.drawText(versionText, 290, 205, true); 改為e.gc.drawText("海康威視資料交換平臺V1.0", 290, 205, true);
3. 修改下面的描述性文字
找到e.gc.drawText(licenseText, 290, 290, true);改為e.gc.drawText("作者：海康", 290, 290, true);
4. 預覽效果
