Question

我意识到下面的长单行代码看起来很荒谬，但请将其视为伪代码。我有一个脚本连续执行11个命令行。我已经使用AutoItX（类似于Selenium）成功实现了它，但这样做实际上只是一个表面级解决方案。模拟按钮点击为错误和中断留出空间，只是感觉不像干净的代码。我希望命令行本身使用Java运行时环境来执行脚本。

sendCommand("cmd cd " + homepath + "\\" + a + "&&" + "mvn archetype:generate -DarchetypeCatalog=file://"+ homepath + "/.m2/repository" + "&&" + "1" + "&&" + c + "&&" + b + "&&" + c + "&&" + uuid.toString() + "&&" + "Y" + "&&" + "cd " + homepath +"\\"+ a +"\\" + b + "&&" + "mvn clean install" + "&&" + "cd " + homepath +"\\" + a + "&&" + "cd " + homepath +"\\" + a +"\\" + b + "\\" + b + "-plugin" + "\\target" + "&&" + "jar -xvf " + zipDirectory + "&&" + "cmd cd " + homepath +"\\" + a +"\\" + b + "\\" + b + "-plugin" + "\\target\\" + "\\META-INF\\maven\\" + c + "\\" + b + "-plugin" + "&&" + "copy pom.xml " + pluginDirectory + "&&" + "cd " + pluginDirectory + "&&" + "rename pom.xml " + b + "-plugin-1.0.0.pom" + "&&" +  "color 0a");

private static void sendCommand(String text) throws IOException, InterruptedException {
    Runtime.getRuntime().exec(text);
}

ProcessBuilder可以接受两个以上的命令行吗？我以前从未见过这种方式。例如，这里有两行：

sendCommand("homepath/plugins", "mvn", "archetype:generate", "-DarchetypeCatalog=file://homepath/.m2/repository");

private static void sendCommand(String workingDirectory, String... command) throws IOException {
    Process proc = new ProcessBuilder(command).directory(new File(workingDirectory)).start();
    int status = proc.waitFor();
    if (status != 0) {
        // Handle non-zero exit code, which means the command failed
    }
}

如何在同一个进程中运行11行，并且只在前一个进程被执行后才执行每一行？

创建一个调用批处理文件的.vbs文件。在批处理文件中写入所有命令。从流程构建器调用.vbs文件。

String ExecutionPath = "pathTo/run.vbs";
final Process process = Runtime.getRuntime().exec("wscript " + ExecutionPath);

Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
    public void run() {
        process.destroy();
    }
}));
process.waitFor();

您的.vbs文件看起来像这样调用批处理文件，并且未显示运行批处理的命令提示符。

Dim WinScriptHost

设置WinScriptHost = CreateObject（＆＃34; WScript.Shell＆＃34;）

Dim oFSO

设置oFSO = CreateObject（＆＃34; Scripting.FileSystemObject＆＃34;）

sScriptDir = oFSO.GetParentFolderName（WScript.ScriptFullName）

WinScriptHost.Run Chr（34）＆amp; sScriptDir＆amp; ＆＃34; \的run.bat＆＃34; ＆安培; Chr（34），0

设置WinScriptHost = Nothing
