Java decompiler plugin not working
提问by HimBromBeere
I have the JD-eclipse-plugin installed. I want to decompile the classes within a jar-file. So I select the jar-file within Project-Explorer and click Decompiler in the Menu. However both decompilers (JAD and JD-core) are greyed out.
我已经安装了 JD-eclipse-plugin。我想反编译 jar 文件中的类。所以我在 Project-Explorer 中选择 jar 文件，然后在菜单中单击 Decompiler。然而，两个反编译器（JAD 和 JD-core）都是灰色的。
I also tried the steps shown in this blog on AVAJAVA Web Tutorials. I guess the blog is a bit outdated, however I can see within Windows-->Preferences-->Java-->Decompiler that Jad is correctly set up. But there is no JD-eclipse found within Preferences-->General-->Editors-->File Associations as you can see in the following image.
. Now I right click the jar-file within Project-Explorer, but there is no such "Attach Source File".
我还在AVAJAVA Web Tutorials 上尝试了此博客中显示的步骤。我想这个博客有点过时了，但是我可以在 Windows-->Preferences-->Java-->Decompiler 中看到 Jad 已正确设置。但是在 Preferences-->General-->Editors-->File Associations 中没有找到 JD-eclipse，如下图所示。. 现在我右键单击 Project-Explorer 中的 jar 文件，但没有这样的“附加源文件”。
Did I miss anything to set up the plugin?
我错过了设置插件的任何东西吗？
EDIT: I′m using the following setup: Eclipse: Mars.1 Release (4.5.1); JadClipse 4.0.0; JDK 1.8
编辑：我正在使用以下设置：Eclipse：Mars.1 Release (4.5.1)；JadClipse 4.0.0; JDK 1.8
EDIT2: Forgot to mention that I use Tomcat and want to dive into the libraries from /WebContent/WEB-INF/lib. This is not working, I cannot further collapse the jar-files.
EDIT2：忘了提及我使用 Tomcat 并想从/WebContent/WEB-INF/lib. 这不起作用，我无法进一步折叠 jar 文件。

Obviously I mixed the actual JD-eclipse-plugin an a plugin called JadClipse for Eclipse which is a slightly different plugin from eclipse marketplace. Thus when I followed the installation instructions of JD-eclipse, I could set the options for the screenshot posted within the question. So I set JD-eclipse as default for both *.class-files with and those without source-code.
显然，我将实际的 JD-eclipse-plugin 和一个名为 JadClipse 的插件混合在一起，这是一个与 eclipse 市场略有不同的插件。因此，当我按照JD-eclipse的安装说明进行操作时，我可以为问题中发布的屏幕截图设置选项。因此，我将 JD-eclipse 设置为带有和不带源代码的 *.class 文件的默认值。
Second mistake I did was a pretty silly and obvious one, namely that I wanted to browse the jar-files from within WEB-INF-folder of my Tomcat instead of from within Java Resources. Thus I could not dive into the jar-files at all hindering me to get to the class-level and thus to decompile those classes contained within the jar.
我犯的第二个错误是一个非常愚蠢和明显的错误，即我想从 Tomcat 的 WEB-INF 文件夹中而不是从 Java 资源中浏览 jar 文件。因此，我根本无法深入研究 jar 文件，这阻碍了我进入类级别，从而反编译 jar 中包含的那些类。
I hope this helps anyone outside also having trouble with the plugin for eclipse.
我希望这可以帮助任何在 eclipse 插件上遇到问题的人。

For Eclipse 2018-09 , the problem was related to " class without source"
对于 Eclipse 2018-09，问题与“ class without source”有关
I had resolved this issue by going to:
- Preferences
- General
- Editors
- File Associations
- Class without source
我已经通过以下方式解决了这个问题：
- 喜好
- 一般的
- 编辑
- 文件关联
- 无源类
and setting decompliler viewer as default : see the following screen shot:
并将反编译查看器设置为默认值：请参阅以下屏幕截图：
回答by lifesoordinary
I had the same problem but "class without source" did have decompliler viewer as default. So all I did was set class file viewer as default and then switched back and that fixed the issue.
我遇到了同样的问题，但“没有源的类”确实有默认的反编译器查看器。所以我所做的只是将类文件查看器设置为默认值，然后切换回来并解决了问题。
