虽然这可能不是正确的错误日志。我已经做了什么。

1. 从更新站点下载 JD-Eclipse
2. 将类文件编辑器设置为默认值。
3. 将类路径添加到项目中的构建路径
4. 在 stackoverflow.com 上提出这个问题

我使用的是 windows xp。

请帮帮我

Answer 1

Eclipse 类文件编辑器不会在工作区中打开不属于 java 项目的 .class 文件（因此您不能使用 File > Open File...）

您可以在https://bugs.eclipse.org/bugs/enter_bug.cgi?product=JDT&component=UI提出增强请求

Answer 2

你必须做的都是错的： 文件 ==> 打开文件 ==> 然后转到您的工作区并进入文件所在的项目文件夹 但不要去我的 bin 文件夹进入 src 文件夹并在最后用 .java 打开文件，现在你已经打开了文件。

文件 ==> 打开文件 ==> 工作区 ==> 项目文件夹 ==> src 文件夹 ==> [名称].java

Answer 3

Editor->File Associations->.java 映射到 Java Editor（默认）

Answer 4

我能够通过在项目属性 => Java 构建路径 => 库 => 添加类文件夹下将包含类文件的文件夹添加为“类文件夹”来修复它。

一旦我这样做了，我就能够正确地反编译所有源代码。就像上面提到的评论一样，它需要成为您工作区的一部分。

Answer 5

右击文件名选择用选项打开，然后按java编辑器选项。
