How do I make a breakpoint in Eclipse Neon using GoClipse? - eclipse

I have a GoClipse project in Eclipse Neon that I am attempting to debug. On my work computer I am able to create a new breakpoint by clicking on the left side of the code window, but on my home computer this is not working. Is there somthing that I do not have enabled on my home computer?
How do I make a breakpoint in Eclipse Neon using GoClipse?

Did you double click on the editor column? Or opened the context menu there? Just a single-click won't work.

Eclipse neon toolbar appeared randomly

recently when I launched eclipse, I had a toolbar added. I want to get rid of it.... It starts with the hammer up to the "local" part. How to get rid of it ?Here is a screen:
That looks like the Eclipse LaunchBar. It used to be packaged as a plugin for Eclipse CDT, but it can now be installed separately from any Eclipse version.
To disable it, go to Window -> Preferences -> Run/Debug -> Launching -> Launch Bar. Unselect the box next to Enable the Launch Bar.

Eclemma on Eclipse Neon (I can't find icon on toolbar)

I installed Eclemma on Eclipse Neon and the guide says I should be able to find an icon on the toolbar like above. However, I cannot find it and I searched online about this problem and saw some people having trouble with it. But I haven't found a solution to it..
I uninstalled and re-installed Eclemma but I still can't find the icon.
I’ve just had the same problem and a web search led me to this page. If you are using Windows 7 and Eclipse Neon, I found I could get the coverage button to appear (and work) if I:
Run Eclipse as administrator (right click and look for the menu item)
Install Eclemma as normal.
If prompted to restart Eclipse, click on “no”.
Manually close Eclipse
Run Eclipse again as administrator.
From eclipse open Window > Perspective > Customize Perspective
Go to "Action Set Availability" tab
In the "Available action sets" pane check "Java Code Coverage" checkbox
Click Ok
Use the keys CTRL + SHFT + F11! It worked on my windows 10.

Eclipse windows will not dock on Ubuntu

I'm running Eclipse Mars on Ubuntu 12.04 LTS and it seems impossible to dock windows in the IDE.
Normally, when you drag a tab to a border of the editor pane, it will dock within the pane. This makes it easy to work on several files at once. But as soon as I start to drag a tab, it creates a detached window. This window has no menu or toolbar and I can find no way to re-attach it to the main editor.
Can anyone suggest a way to make the Eclipse windows behave normally?
Seems like it was some kind of transient display problem. Closing Eclipse and rebooting fixed it. I guess I should have tried that first :S

Why is my System.out.println not printing anything in my eclipse plugin?

Using eclipse PDE, I'm running into this very strange error. I start up my plugin by right clicking on the project, Run As -> Eclipse Application.
The target eclipse seems to start up just fine, and in my development eclipse, a console view shows up but it's empty. I can't see any System.out.println's or any exception stacktraces or any of the usual stuff in there.
Answer to my problem below.
It turns out, a different feature I have installed in my eclipse, Scala IDE, is the culprit. For some reason, when it's active, it causes my console to be blank.
To disable it in the target eclipse:
right click on the project
Run As -> Run Configurations
Select the Eclipse Application configuration you've been using.
Go to the Plugins tab
Uncheck everything in sight with "Scala" in it.
Console came back after doing this!

debugging in Eclipse will defocus when stepping into a new editor

I recently switched from Eclipse Galileo to Eclipse Juno. On Juno I found out a very annoying inconvenience: Whenever I am debugging and I step from one editor into another (when pressing F5 steps into another file), the focus is lost and I have to click on the new editor in order to continue using F5 or F6. In Galileo, I would continue debugging by pressing F5 without having to re-focus the editor. Is that a bug, a change or a feature with options that I could switch off?
thanks.
it seems you're no alone with this problem in Juno. Take a look at this bug in eclipse maybe it will help you:
