从 C# 执行 a.jar 文件，但它在错误的位置生成文件

Question

I have coded a Minecraft Server Runner in C# WinForms which lets you run a Minecraft Server, a.jar file which needs to generate files. The problem is that I launch this.jar file via the.exe application, and the files generate at the.exe application location.

-- What I have tried:

I tried moving the.exe application to the specific server file location, but the application needs a restart to register this change which I don't want to happen.

I also don't want the user being forced to put the.exe application to the Server folder and restart it. Here is the code I use to launch the.jar file:

Process.Start("C:\user\documents\server\server.jar");

How can I fix this issue?

Answer 1

The jar file can be executed by the java -jar filename.jar . So use the following Process.Start call to invoke the jar.

Process.Start("java", "-jar C:\user\documents\server\server.jar", username, password, domain);

Hope this helps.

PS: For this to work, either add the Java to your path or invoke with the java.exe's Path.

Answer 2

To fix this I executed the.jar file in the C# application via the CMD. Here is the code I used instead:

string path = @"C:\user\documents\server\"; //Path to your server.jar file.
var process = new System.Diagnostics.Process();
process.StartInfo.FileName = path + "server.jar"; //Name of the .jar file.
process.StartInfo.WorkingDirectory = path;
process.StartInfo.UseShellExecute = true;
process.Start();
