我正在尝试通过Java类的main方法执行gradle build命令（使用cmd提示符）。

public class GradleScriptEditor {

    public static void main(String[] args) throws IOException {
        String command_to_be_executed = "gradle build";
        String directory_location = "C:\\mycode\\ws";

        String[] command = {command_to_be_executed};
        ProcessBuilder builder = new ProcessBuilder(command);
        builder = builder.directory(new File(directory_location));

        Process p = builder.start();
        OutputStream outputStream = new FileOutputStream(new File(directory_location+ "/mylog.log"));
        outputStream.write(p.getInputStream().readAllBytes());
        outputStream.close();
    }
}

但我得到了以下错误：

Exception in thread "main" java.io.IOException: Cannot run program "gradle build" (in directory "C:\\mycode\\ws"): CreateProcess error=2, The system cannot find the file specified
    at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1143)

请注意，当我使用ipconfig测试我的代码时，它工作正常。
请告诉我如何解决这个问题。
