java - 如何让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)

但是:

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

完美运行。但在cmd中两者都运行良好!如何让java像cmd一样运行？

Answer 1

new ProcessBuilder("mvn"); 没有诸如 mvn.exe 或 mvn.bat 之类的扩展名，这会导致您的应用程序将其作为文件夹读取。
