Okay, I have a problem, I'm creating a launcher for Minecraft. My problem: I get this error messege, when I try launch Minecraft: Error: Could not find or load main class net.minecraft.client.main.Main
My code, I writted this, but not works:
The Detail of code:
Logger as module, my program using this to write information to console.
JavaPaht as string, the Java path is stored in this.
GameLibraries as string too, the libraries stored in this.
MinMemAlloc as string, the minimal allocated memory for java.
MaxMemAlloc as string, the maximal allocated memory for java.
Root as string, this is the root directory of Minecraft.
Here is the full sub to launch game:
Private Sub LaunchGame()
If Not File.Exists(Root + "\versions\" + SelectedGameVersion + "\" + SelectedGameVersion + ".jar") Then
MsgBox("File not found: " + SelectedGameVersion + ".jar")
Else
Logger.Write("Launching Game...")
Logger.SetScrollDown()
Dim Gamelibraries As String = Nothing
For i = 0 To FileList.Count - 1
Gamelibraries += FileList.Item(i) + ";" +
Environment.NewLine()
Next
Logger.WriteWithJumpDown("Libraries loaded: " & Gamelibraries.ToString())
Logger.SetScrollDown()
Logger.Write("Building Process...")
Logger.Write("Received data: ")
Logger.SetScrollDown()
Dim p As New Process()
p.StartInfo.FileName = JavaPath
p.StartInfo.Arguments = " -Xms" + MinMemAlloc + "M -Xmx" + MaxMemAlloc + "M " +
"-Djava.library.path=" + Root + "\versions\" + SelectedGameVersion + "\" + SelectedGameVersion + "-natives -cp " +
Gamelibraries.ToString() +
Root + "\versions\" + SelectedGameVersion + "\" + SelectedGameVersion + ".jar " + mainClass +
" --username=" + UserID +
" --version " + SelectedGameVersion +
" --gameDir " + Root +
" --assetsDir " + Root + "\assets" +
" --assetIndex " + assets +
" --accessToken null" +
" --userProperties {}" +
" --userType mojang" +
" --uuid (Default)"
p.StartInfo.WorkingDirectory = Root
p.StartInfo.CreateNoWindow = False
p.StartInfo.UseShellExecute = False
p.EnableRaisingEvents = True
Application.DoEvents()
p.StartInfo.RedirectStandardError = True
p.StartInfo.RedirectStandardOutput = True
AddHandler p.ErrorDataReceived, AddressOf p_OutputDataReceived
AddHandler p.OutputDataReceived, AddressOf p_OutputDataReceived
p.Start()
p.BeginErrorReadLine()
p.BeginOutputReadLine()
Logger.SetScrollDown()
Button1.Text = "Play"
Button1.Enabled = True
Button2.Enabled = True
Button3.Enabled = True
Button4.Enabled = True
Button5.Enabled = True
End If
End Sub
And my program writing the output into my console, so I write here the output:

Thanks for help!
You need to have the main class on the path after the jars are included "net.minecraft.client.main.Main" unless mainClass means that already, then I don't know.
