[英]unable to execute the jar file using java program. i need to pass the file path as a command line argument to the jar file
下面的代码无法写入文件。
我写了一个程序来执行cmd中的命令。 这些命令不过是执行jar文件中的java文件而已。 此jar文件中的java文件期望文件路径作为命令行参数。
注意：-jar文件也仅由我创建。

问题是调用它时传递给Jar文件的内容。 您的Jar文件设置为使用它收到的第一个参数作为您要使用的目录：
public static void main(String[] args) {
...
String filepath = args[0];//.replace("\" , ", "\\"); // First parameter
File directory = new File(filepath);
....
但是，当您调用它时，实际上是将“ readExcelDemo.Final”作为第一个参数传递，而不是您希望目录成为的样子：
File directory = new File("C://Users//kondeti.venkatarao//Documents//Regresion_sheets//custome");
...
for (File file: files) {
...
Runtime.getRuntime().exec("java -jar Demo.jar readExcelDemo.Final " + file.getAbsolutePath());
因此，您的解决方案将是三件事之一：
希望有帮助〜
编辑：
PS：我假设您也没有任何异常，因为它确实在工作，但是包含结果的目录将位于您的根项目目录/readExcelDemo.Final中，而不是您希望使用的路径
PPS：另外，您的执行命令不需要cmd.exe /c start的第一部分，而应替换为：
Runtime.getRuntime().exec("java -jar Demo.jar readExcelDemo.Final " + file.getAbsolutePath());
在我的原始帖子的第一部分中，我还随意替换了它。
