vb.net如何启动Minecraft？

Question

好的，我有一个问题，我正在为Minecraft创建启动器。 我的问题：尝试启动Minecraft时遇到此错误消息： Error: Could not find or load main class net.minecraft.client.main.Main

我的代码是我写的，但是没有用：

详细代码：

记录器作为模块，我的程序使用它向控制台写入信息。

JavaPaht作为字符串，Java路径存储在其中。

GameLibraries也作为字符串存储在此库中。

MinMemAlloc作为字符串，为Java分配的最小内存。

MaxMemAlloc作为字符串，Java的最大已分配内存。

根作为字符串，这是Minecraft的根目录。

这是启动游戏的完整子目录：

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

我的程序将输出写入控制台，所以我在这里写入输出：

在罐子包含在内之后，您需要在路径上具有主类“ net.minecraft.client.main.Main”，除非mainClass已经表示，那么我不知道。
