Question

我试图为Minecraft制作自定义发射器。我只是想从我自己的服务器下载主jar文件，没有别的。我反编译了一个文件（Launcher.java）并更改了＃34; https://s3.amazonaws.com/Minecraft.Download/＆＃34;的下载网址。对我自己。问题是，当我尝试用javac -classpath launcher.jar launcher.java重新编译它时会抛出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 }));

有没有办法做到这一点？不要介意我的写作风格，我试着整夜解决......

提前致谢。

我自己想通了！我需要这样做：

import java.io.FileFilter;

然后修改

中的每个错误行

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

到此：

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

现在一切正常。

Minecraft Launcher重新编译
