質問

PythonでMinecraft 1.12.2用のランチャーを書いたのですが、コマンドを用意してサブプロセスを使って実行するだけです。

これはLinux Ubuntuで形成されたコマンドです。

問題点 Ubuntu版では文句なく実行されるのに Windows版では

プレ Error: Could not find or load main class net.minecraft.launchwrapper.Launch

と表示され、全く起動しない。

このように、UbuntuとWindowsのコマンドはほとんど同じです。

私が起動しようとしている minecraft インストール(Ubuntu と Windows の両方で使用)は Windows から来ており(公式ランチャーで生成、forge をインストール、プラットフォームに依存するためネイティブとマークされたライブラリのみ置き換える)、両方のプラットフォームで公式ランチャーを使って問題なく起動できるため、minecraft ファイルの欠落や破損は問題ないものと思われます。また、カスタムランチャーでも起動できましたが、上に書いたように Ubuntu でのみ起動できました。

私は何が間違っているのか、皆さんは何か提案を持っていますか?

PS 私のカスタムランチャーを使ってバニラマインクラフトを起動しようとしましたが、問題は全く同じで、Ubuntuでは動作しますが、Windowsでは同じエラーで失敗します(もちろん、代わりにバニラクラスと表示されます)。

EDIT Python のコードは長いので提供しません。ネイティブを一時フォルダに展開し、minecraft を起動するコマンドを形成するだけなので、手書きで書いてスクリプトに貼り付けて実行するだけです。

どのように解決するのですか?

実は、Windowsでは、クラスパスのセパレータは.ではなく、;なのです。 セパレータを置き換えることで、この問題は解決します。
