ant自動打包腳本使用到的build-ant-utils.jar（java源碼）

ant自動打包腳本用到的java工具類代碼，一共三個類，打成jar後放到ant安裝路徑lib文件夾下

第一個

import java.io.File;
import java.io.IOException;

/** 
 * @author 
 * @time 2018-5-4 下午2:43:41 
 * 類說明：替換assest文件夾下參數配置文件
 */
public class ReplaceAssestParams {

	public static void main(String[] str){
		//接收到ant傳進來的參數值
		String key1 = str[0];
		String key2 = str[1];
		String key3 = str[2];
		System.out.println("key1："+key1+", key2："+key2+", key3："+key3);
		
		//拼接pywsdk文件路徑
		String pywsdkPath = key3+"/pywsdk.data";
		//拿到pywsdk中的字符串
		String content = FileUtils.readContent(pywsdkPath);
		
		//先複製一份字符串到TXT，用於編譯完成後改回原來默認的值
		String backupsPath = key3+"/backups.txt";
		File backupsFile = new File(backupsPath);
		if(!backupsFile.exists()){
			try {
				backupsFile.createNewFile();
			} catch (IOException e) {
				e.printStackTrace();
			}
		}
		//寫入到TXT中
		FileUtils.writeContent(backupsFile, content); 
		
		//進行參數替換
		content = content.replace(key1, key2);
		File pywsdkFile = new File(pywsdkPath);
		//寫入到pywsdk文件中
		FileUtils.writeContent(pywsdkFile, content);  
		System.out.println("替換參數結果："+content);
	}
}

第二個

import java.io.File;

/** 
 * @author  
 * @time 2018-5-8 下午4:57:46 
 * 類說明：將備份的內容複製進pywsdk文件中
 */
public class ReplaceBackAssestParams {

	public static void main(String[] str){
		
		//接收到ant傳進來的參數值
		String key1 = str[0];
		System.out.println("key1："+key1);
				
		//拼接備份TXT文件路徑
		String backupsPath = key1+"/backups.txt";
		//拿到備份TXT中的字符串
		String content = FileUtils.readContent(backupsPath);
		
		//拼接pywsdk文件路徑
		String pywsdkPath = key1+"/pywsdk.data";
		File pywsdkFile = new File(pywsdkPath);
		//寫入到pywsdk文件中
		FileUtils.writeContent(pywsdkFile, content);  
		System.out.println("替換回參數結果："+content);
		FileUtils.deleteFile(backupsPath);
	}
}
