我一直在和Guice玩，无意中发现了这个错误，这对我来说似乎没有什么意义。似乎每当注入过程中发生错误时，Guice都会因为消息格式错误而无法正确地记录注入错误。这可能是Guice内部的一个bug，我不完全确定。

正在使用maven-shade-plugin构建jar，其中包括jar本身中所需的依赖项。查看jar的内容，它确实包含了NoClassDefFoundError所引用的类。注入本身工作非常好，只要它没有遇到任何类，它就不能正确地注入。

令人奇怪的是，发生异常的代码与缺少的类位于完全相同的文件中。以下屏幕截图是使用IntelliJ的内置反编译器拍摄的：

通过winrar访问com.google.inject.internal的jar内容：

所以，这可能不是任何人所期望的解决方案(包括我)。

事实证明，我使用的库名为spigot (bukkit上的一个扩展)，它有自己的类加载器实现。这个类加载器似乎无法正常工作，即使类位于类路径中，也无法加载子类。

一旦找到问题的原因，我能想到的唯一方法就是使用Google手动加载类。这已经解决了这个问题，尽管以一种非常肮脏的方式。不过，它只需要运行一次，所以我已经将它保存在一个方法中，该方法名为在此bug上调用bukkit。

如果你想知道我是怎么修好它的，那就准备一次狂野的旅行吧：

代码语言：javascript
复制
    List<String> toLoad = Arrays.asList(
            "com.google.inject.internal.Messages$FormatOptions",
            "com.google.inject.internal.util.LineNumbers",
            "com.google.inject.internal.util.LineNumbers$LineNumberReader",
            "com.google.inject.internal.PackageNameCompressor",
            "com.google.inject.internal.ErrorFormatter"
    );

    try {
        Set<ClassPath.ClassInfo> cp = ClassPath.from(ValvePlugin.class.getClassLoader()).getAllClasses();
        for (ClassPath.ClassInfo x : cp) {
            if (toLoad.contains(x.getName())) {
                x.load();
            }
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

这段代码手动扫描整个类路径中的所有类(我找不到一种快速方法只扫描一个包，同时也包括子类)，并加载列表中的任何名称。
