在Java中调用Ant命令

在Java程序中调用Ant命令有几种方法，下面介绍两种常用的方式：

1. 使用Runtime.exec()方法

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;public class AntRunner {public static void main(String[] args) {try {// 指定Ant命令和构建文件String antCommand = "ant -f build.xml targetName";// 执行命令Process process = Runtime.getRuntime().exec(antCommand);// 读取输出BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));String line;while ((line = reader.readLine()) != null) {System.out.println(line);}// 等待命令执行完成int exitCode = process.waitFor();System.out.println("Ant命令执行完成，退出码: " + exitCode);} catch (IOException | InterruptedException e) {e.printStackTrace();}}
}

2. 使用ProcessBuilder（更推荐）

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;public class AntRunner {public static void main(String[] args) {try {// 创建ProcessBuilder并设置命令ProcessBuilder pb = new ProcessBuilder("ant", "-f", "build.xml", "targetName");// 设置工作目录（可选）// pb.directory(new File("path/to/ant/project"));// 合并错误流和输出流pb.redirectErrorStream(true);// 启动进程Process process = pb.start();// 读取输出BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));String line;while ((line = reader.readLine()) != null) {System.out.println(line);}// 等待命令执行完成int exitCode = process.waitFor();System.out.println("Ant命令执行完成，退出码: " + exitCode);} catch (IOException | InterruptedException e) {e.printStackTrace();}}
}

3. 使用Ant的Java API（高级用法）

如果你需要更精细的控制，可以直接使用Ant的Java API：

import org.apache.tools.ant.DefaultLogger;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.ProjectHelper;public class AntApiRunner {public static void main(String[] args) {// 创建Ant项目Project project = new Project();// 配置日志DefaultLogger logger = new DefaultLogger();logger.setErrorPrintStream(System.err);logger.setOutputPrintStream(System.out);logger.setMessageOutputLevel(Project.MSG_INFO);project.addBuildListener(logger);// 初始化项目project.init();// 解析构建文件ProjectHelper helper = ProjectHelper.getProjectHelper();helper.parse(project, new File("build.xml"));// 执行特定目标project.executeTarget("targetName");}
}
