When I create a jframe within a java project it shows me all the code in the Source part but when I go to Design it shows nothing? Would like some help on how to get the whole interface where you customise the GUI.
That's a known issue of the Eclipse 2020-09 release which is already fixed (see Eclipse bug 567071).
Update to WindowBuilder 1.9.4 either via the Eclipse Marketplace or via Help > Install New Software... and working with the update site http://download.eclipse.org/windowbuilder/latest/.
I have a simple Eclipse Java project that consists in only one Class made with Eclipse's Window Builder (Swing class). The coding was made on my notebook, and saved on cloud, so I could access It from my home's computer.
When I opened this project in this home computer, I noticed I had not installed Window Builder on it yet, so I installed and restarted Eclipse.
The problem is that even tho I installed WB, Eclipse still doesn't show the Design tab on this class. Did I miss something?
Simply restarting Eclipse a couple times somehow made it work, everything good!
Missing Source/Design tabs
When you open your Swing Project, follow these steps to show Source/Design tab:
Right click on your file Swing.java for example
Choose open with Window Builder editor
This will bring you back the Source and Design Panels
I'm new to the WindowBuilder tool of Eclipse (or any frontend dev), and I installed WindowBuilder, SWT to check it out.
When creating a new project, I go to:
New > Others > WindowBuilder > SWT Designer > SWT/JFace Java Project
When creating a new class, I go to:
New > Others > WindowBuilder > Swing Designer > Application Window or JFrame, or Under > SWT Designer > SWT >Application Window.
This generates an initial Main code and I have Source and Design Tabs below.
My problem is that when going to the design tab it's always empty as seen below:
The initial code in class has this:
And when executed creates this window:
I can't find any answers for this problem, and all tutorials I'm seeing have items inside the Design Tab where they can start exploring it.
Go to Help -> Eclipse Marketplace -> Installed and then update(if not updated) both WindowBuilder and WindowBuilder Nightly
then Restart
to open file with design tab :
righclick on .java file Open With -> WindowBuilder Editor
finally click on design tab it may take few seconds to load
Uninstall eclipse completely, the only thing you need to leave is the eclipse-workspaces folder, so your projects will remain saved.
To uninstall it completely you need to:
Delete the "eclipse" folder in "C:\Users\YourName".
Delete the desktop shortcut.
Delete the ".p2" folder in "C:\Users\YourName".
Reinstall eclipse from the official site.
This worked for me.

I think it will work.
I faced the same problem, and what i did was to update the windowbuilder to version: 1.9.2......
That solved the problem for me.
PS: Using Eclipse Photon
I have generated a demo popup menu plugin project automatically by Eclipse. Here is the project structure,
I have set a objectContribution to the point org.eclipse.ui.popupMenus,
When I right click the project and choose Run as -> Eclipse Application, another Eclipse process run and I can see the configured menu works well,
How can I install this plugin for my original Eclipse process?
What I have tried
I did some research and tried to Export -> Deployable plug-ins and fragments, then put it into the %EclipseFolder%/plugins, but it didn't work. I also have tried to Export -> Deployable features and installed it by Help->Install New Software, also failed to see the menu when right click the project.
Will you please help? BTW, I would like to know how to contribute a menu which will display when I right click on a package in a project? Thanks so much.
Use the Deployable plug-ins and fragments wizard and select Intall into Host on the Destination page.
This will create a p2 repository at the denoted location and install the selected plug-ins from there into the host instance, i.e. the Eclipse IDE that you are currently working with. I think a restart may be required.
The GUI for managing plugins in Eclipse got a bit of an overhaul in version 3.4.0.
This GUI is accessed via the "Software Updates..." option in the Help menu.
The option to remove the selected Mylyn plugin is greyed out. In fact, this is true of virtually every installed plugin. I know that the Mylyn plugins are optional, so why amn't I provided with an option to remove them?
The following text is quoted from the Eclipse help docs:
The Uninstall wizard allows you to review and uninstall items in your configuration. This wizard is shown when you select items and press Uninstall... from the Installed Software page. To uninstall software from your system:
Click Help > About and then click Installation Details... to open a dialog showing pages that provide more detail about your installation.
Click the Installed Software tab to see a list of the software items that you have installed into your system.
Select the items that you wish to uninstall.
Click Uninstall...
The Uninstall Details page will show you a list of the items that will be uninstalled. Expanding each item will show what additional items (if any) will be uninstalled as a result of your choice.
If you change your mind about which items should be uninstalled, you may click Back to see a checkmark list of the items you selected before. You may check and uncheck different items in the list, and click Next when you are ready to continue.
Click Finish to start the uninstall.
Once all of the software is uninstalled successfully, you will be prompted to restart for the Workbench. Click Yes when asked to exit and restart the Workbench for the changes to take effect.
And just to update it for Helios - Eclipse 3.6
Help->Install New Software at the bottom of dialog there is link What is already installed once you click on that you will get list of installed plugins and Uninstal... button
eclipse 3.5(Galieo)
Help>> Install New Software >> Already Installed Plugins >> select Plugins >> Uninstall works charm.
There are distributions of Eclipse that come packaged with certain plugins that can't be mix-and-matched. That is the case with Mylyn, that went from a student's thesis project to an integral part of Eclipse. If you want to actually get rid of Mylyn, you may want to install Eclipse classic instead of the distribution you have, and then install the stuff you need.
The standard Eclipse distributions come with Myln.
BTW, Eclipser 3.5 completely changes all these screens :(
If you are using Windows, make sure you are running Eclipse as administrator. Without administrator privileges, some options may be grayed-out in "Installed Software".
In eclipse Helios (version 3.6), to uninstall a plugin:
Go to Help->Install New Software...
Click on "What is already installed?" link at the bottom right side of the dialog
In the Installed Software tab choose the software you want to uninstall
Click on the "Uninstall..." button at the bottom
Click 'Finish' on the Uninstall Details dialog
Observe the 'Uninstalling Software %' status at the bottom status bar of eclipse
Click 'Restart Now' when prompted to do so.
Eclipse restarts. Choose the workspace. Now when you go again to the Installed Software window , you do not find the uninstalled software.
In Eclipse 3.6 Helios, the interface has changed again. Go to "About Eclipse", and then click the "Installation Details" button in the about box.
While Help → About Eclipse IDE [or wherever it was in the past or will be in the future] → Installation Details → Installed Software → Uninstall... is the official and preferred way there are features/plugins the latter button of which is disabled.
Remember also that there aren't only plugins but features too. In my case I wanted to remove Mylyn and Wild Web Developer from a rather fresh Eclipse IDE for Enterprise Java and Web Developers package. I did the following.
But first a:
DISCLAIMER
Enter ECLIPSE_HOME at your own risk. Mistakes like typos might be in the following, too. I take no responsibility for whatsoever.
Created the directories features.DISABLED and plugins.DISABLED in Eclipse's home dir.
Moved *mylyn* from ECLIPSE_HOME/features to ECLIPSE_HOME/features.DISABLED
Moved *wildwebdeveloper* from ECLIPSE_HOME/features to ECLIPSE_HOME/features.DISABLED
Moved *mylyn* from ECLIPSE_HOME/plugins to ECLIPSE_HOME/plugins.DISABLED
Moved *wildwebdeveloper* from ECLIPSE_HOME/plugins to ECLIPSE_HOME/plugins.DISABLED
After starting Eclipse there were about a dozen "not found" errors in Eclipse's Error Log view. If you double-click on each of them you can see which dependency plugin JAR(s) haven't been found.
Set the Error Log view's filter to just display errors and warnings.
Moved the dependency plugin *.jars mentioned in the errors from ECLIPSE_HOME/plugins.DISABLED back to ECLIPSE_HOME/plugins one by one (with Eclipse restart after each) until no "not found" error appeared in the view any longer. It were nine *mylyn*.jars in the end.:
*.mylyn.commons.core_*
*.mylyn.commons.net_*
*.mylyn.commons.notifications.core_*
*.mylyn.commons.notifications.ui_*
*.mylyn.commons.screenshots.ui_*
*.mylyn.commons.ui_*
*.mylyn.commons.workbench_*
*.mylyn.commons.wikitext.markdown_*
*.mylyn.commons.wikitext.*
Note that this applies to a rather fresh Eclipse 2021-03 (4.19.0) installation. It might be different from one – even patch – version to the other.
Furthermore:
Keep Eclipse's Error Log view open for a while. The underlying OSGi activates bundles (plugins) on the fly if they are referenced from an other bundle (plugin) for the first time. And if one isn't there then...
Check the Error Log view especially after installing new features/plugins. They might rely on plugins/JARs you moved to .DISABLED. If that's the case move the according JAR(s) back to ECLIPSE_HOME/plugins and/or ECLIPSE_HOME/features.
If something doesn't work as it did in the past once in the future remember what you did and ... → Error Log view.
I'm running (a relatively fresh copy of) 3.4.1. I was able to select the same plug-in shown in your screen shot (Mylyn Bridge: Java Development) to get an enabled "Uninstall..." button. I'd suggest getting the latest updates and trying again.
It sure looks like there's no way to do this.
I just had exactly this problem with a fresh download of the Eclipse Java IDE (Ganymede SR2). I didn't want Mylyn, but I didn't want "Eclipse Classic", either, because the download was twice the size, I presume because it includes source.
The apparent solution was to update everything and restart Eclipse, after which the "Uninstall..." button became enabled for the Mylyn plugins. Unfortunately, this only uninstalled the most recent, updated version (3.0.11 IIRC), reverting to the un-uninstallable 3.0.5.
I just don't know what the hell these Eclipse developers are thinking! Removing plug-ins from Eclipse became a pain in the ass since Helios!
I hear you pal... I just went through the whole day trying to figure out as no one seems to give an straight answer like "do this, that, done."
Man I'd rather be programming instead....
Found, in the middle of my evening that it is possible to uninstall pretty much everything. The issue is that the damn thing is hidden in the "HELP->ABOUT". Who would guess after going over and over through the "Help->Install New Software" or "Help->Check for updates" and never finding anything like "remove" or "reinstall" or "force reinstall".
Seriouly, I'd rather go back to 1990 when we had Microsoft, Borland and Watcom.. you picked your platform and you'd be with 1/3 of the world of developers with you.. ok, perhaps Watcom didn't hit that mark but you get the point.
So... to uninstall any plugin from Eclipse Helios (Service Release 1) or Springsource 3.5.2 (or 3.6.1 I 'm using), do this:
close all your projects (just to be on the safe side);
Hit menu "HELP-->ABOUT" (yeah.. help, about);
Hit "Installation Details" button and you get the list with all plugins;
Click on the one you want to remove; hit uninstall;
If want to remove more than one, just apply the change without restart;
Goto to 4) as needed
Finally, restart Eclipse and reinstall what you need !
It was hard to find, but it worked very well for me.
