Variables not showing while debugging in Eclipse
提问by well actually
I am running Eclipse Galileo for developers.
我正在为开发人员运行 Eclipse Galileo。
When I run in debug mode, the current variables and their values are not coming up in the Variableswindow. The window remains empty when I step through my code after a breakpoint.
当我在调试模式下运行时，当前变量及其值不会出现在“变量”窗口中。当我在断点后单步执行代码时，窗口保持为空。
Last night it was working, so I'm perplexed. Any reason why this might be happening and any tip on troubleshooting?
昨晚它正在工作，所以我很困惑。发生这种情况的任何原因以及有关故障排除的任何提示？

I ended up trying something easy by resetting the Debug perspective, which seemed to work:
我最终通过重置调试视角来尝试一些简单的方法，这似乎有效：
Window => Perspective => Reset Perspective...
窗口 => 透视 => 重置透视...
Thanks for the comments.
感谢您的评论。

Window --> Show View --> Variables
窗口 --> 显示视图 --> 变量

My problem was that I couldn't see variables names, but just the value. After trying quite a while I got the solution: Click on the down arrow (in degub Variables tab) --> Layout --> show columns
我的问题是我看不到变量名称，而只能看到值。尝试了一段时间后，我得到了解决方案：单击向下箭头（在调试变量选项卡中）--> 布局--> 显示列
It did the trick!
它成功了！

Resetting the perspective wasn't quite enough for me, I had to first delete the "Variables" tab and then reset the perspective (which reinstated the Variables tab in a working state). One other thing not mentioned above which might help others - when the variables tab is not working, the tab title is in italics (whatever that signifies). When it's working it goes back to normal font.
重置视角对我来说还不够，我必须首先删除“变量”选项卡，然后重置视角（这将变量选项卡恢复到工作状态）。上面没有提到的另一件事可能会帮助其他人 - 当变量选项卡不起作用时，选项卡标题为斜体（无论表示什么）。当它工作时，它会恢复正常字体。

I restarted Eclipse and it worked again.
我重新启动了 Eclipse，它又工作了。

Windows -- > showView --> variable
Windows --> showView --> 变量
or you can reset the perspective
或者你可以重置视角
windows -- > preferences -- > perspective --> restore Defaults
windows --> 首选项 --> 透视 --> 恢复默认值

try a right click on the variable and select inspect, then it should come up in a popup window
尝试右键单击变量并选择检查，然后它应该出现在弹出窗口中

I found I needed to remove static declarations if I wanted to see the variables, but this works better...
我发现如果我想查看变量，我需要删除静态声明，但这效果更好......

What worked for me is the following: I had a blank Variables view for the top stack frame. I selected a lower stack frame, then reselected the top one, and the Variables view refreshed itself somehow. Note: I'm using Eclipse Mars, so this bug appears to have returned in this version (or perhaps it's a different one, with the same symptoms?).
对我有用的是以下内容：我有一个顶部堆栈框架的空白变量视图。我选择了一个较低的堆栈框架，然后重新选择了顶部的一个，并且变量视图以某种方式刷新了自己。注意：我使用的是 Eclipse Mars，所以这个 bug 似乎在这个版本中又回来了（或者它可能是一个不同的，具有相同的症状？）。

Also: your process needs to be suspended for Eclipse to show variables. If it is running, Eclipse won't show any variable.
另外：您的流程需要暂停以便 Eclipse 显示变量。如果它正在运行，Eclipse 将不会显示任何变量。
To suspend a thread, select a thread in the "debug" view, and hit "Suspend"
要暂停线程，请在“调试”视图中选择一个线程，然后点击“暂停”
