如何使Java运行可执行应用程序？

Question

代码：

ProcessBuilder pb = new ProcessBuilder("mvn");
Process p = pb.start();

输出：

java.io.IOException: Cannot run program "mvn": CreateProcess error=2, The system cannot find the file specified
at java.lang.ProcessBuilder.start(Unknown Source)
at com.littleHelper.app.ButtonDemo.actionPerformed(ButtonDemo.java:47)

可是：

ProcessBuilder pb = new ProcessBuilder("mvn.bat");
Process p = pb.start();

完美运行。但在cmd中运行良好！如何让java像cmd一样运行？

Answer 1

new ProcessBuilder("mvn");没有类似mvn.exe或mvn.bat的扩展程序，导致您的应用程序将其作为文件夹读取。
