Minecraft Launcher重新编译

Question

我正在尝试为Minecraft制作自定义启动器。我只想让它从我自己的服务器下载主jar文件，仅此而已。我反编译了一个文件（Launcher.java）并将下载url从“https://s3.amazonaws.com/Minecraft.Download/”更改为我自己的。问题是，当我尝试使用javac-classpath重新编译它时launcher.jarlauncher.java它会抛出5个错误：

launcher.java:313: error: reference to listFiles is ambiguous, both method listFiles(FilenameFilter) in File and method listFiles(FileFilter) in File match File[] directories = objectsDir.listFiles(DirectoryFileFilter.DIRECTORY);

launcher.java:317: error: reference to listFiles is ambiguous, both method listFiles(FilenameFilter) in File and method listFiles(FileFilter) in File match File[] files = directory.listFiles(FileFileFilter.FILE);

launcher.java:409: error: reference to listFiles is ambiguous, both method listFiles(FilenameFilter) in File and method listFiles(FileFilter) in File match File[] directories = virtualsDir.listFiles(DirectoryFileFilter.DIRECTORY);

launcher.java:441: error: reference to listFiles is ambiguous, both method listFiles(FilenameFilter) in File and method listFiles(FileFilter) in File match File[] versions = root.listFiles(DirectoryFileFilter.DIRECTORY);

launcher.java:445: error: reference to listFiles is ambiguous, both method listFiles(FilenameFilter) in File and method listFiles(FileFilter) in File match File[] files = version.listFiles(FileFilterUtils.and(new IOFileFilter[] { new PrefixFileFilter(version.getName() + "-natives-"), ageFilter }));

有什么办法吗？别介意我的写作风格，我试图解决这整个晚上...

提前谢谢。

Answer 1

我自己想出来的！我需要这样做：

import java.io.FileFilter;

然后修改

File[] directories = objectsDir.listFiles(DirectoryFileFilter.DIRECTORY);

对此：

File[] directories = objectsDir.listFiles((FileFilter) DirectoryFileFilter.DIRECTORY);

现在一切都正常了。
