I was trying to set up GWT(Google Web Toolkit) on my system using it as a plugin for eclipse Indigo. I am currently on a Ubuntu workstation. Upon restart after the installation, eclipse simply crashes without any error info. I did look around here on stack overflow , as well as on google about what could be done, but the things which seemed to work for others do not seem to work for me.( deleting certain .jar files, deleting the metadata folder in the workspace).
Any help would be great.
Regards
Problem solved. There is a bug in Indigo , exposed by the plugin. All that needs to be done is to check for updates first and then install the plugin. The bug has been fixed in one of the point updates.

I have Eclipse Juno with Java EE, PHP, C++ and PyDev in it and it was working perfectly under Ubuntu 12.04 and later under 14.04.
Yet, when I upgraded my OS to Ubuntu 14.10, Eclipse doesn't work anymore, whenever I try to open it, it shuts down immediately.
I want to upgrade it to Luna but it doesn't give me the chance to launch the upgrade, I have an idea I have and wish to hear your advice on whether it is right or wrong.
What I'd like to do is to download Luna and extract it over the older version.
Will this work? Or will it make it even worse?
Is there anyone who tired it before?
You may even download Luna, and extract it to a different folder (not necessary on top of the older version).
Afterwards, launch Luna and try to load your previous workspace(s). You might want to backup your workspaces folder, before letting Luna attempt and load from there.
Updating the eclipse through the command line is safer. Try it using eclipse site
and also refer to this answer
I find solution here https://bugs.eclipse.org/bugs/show_bug.cgi?id=440660#c20 on comment 20
This seems to be a bug in GTK according to https://bugs.launchpad.net/ubuntu/+source/gtk2-engines-oxygen/+bug/1242801
(there a similar problem for Meld was reported).
Another workaround mentioned there is
For oxygen, edit the normally already existing file "/usr/share/themes/oxygen-gtk/gtk-2.0/gtkrc" and change
GtkComboBox::appears-as-list = 1
into
GtkComboBox::appears-as-list = 0
This workaround is working for me.
I am not an Eclipse/RAP developer, but over a year ago I was tasked with getting a particular application to run. The development environment was Eclipse/RAP using Java. The application was already almost done -- I just needed to make a few changes to get it to work the way we wanted it to work. I made the changes, stuck it into the Jboss app, and it worked. I saved away my source code.
Since then they upgraded my PC, so I no longer have access to my old development environment. We need to move the RAP application to another server, and for some reason it has quit working. Either I don't understand why it ever worked or I don't understand why it doesn't work -- it's all a bit baffling.
So now I'm trying to get this thing working again.
The basic problem I haven't been able to resolve is dependencies. Eclipse reports that the following three bundles can't be found:
org.eclipse.rap.draw2d
org.eclipse.rap.zest.core
org.eclipse.rap.zest.layouts
All three should be in the GEF package.
I have tried installing Eclipse Indigo. When I do that, Eclipse can't find GEF to install it, even though it's given the same URL as I give to Kepler. I've installed Eclipse Kepler. I can install GEF, but while Eclipse reports a valid install, and reports that it is installed, I'm still seeing the same missing dependencies.
Any ideas? It's baffled an Eclipse developer here, but then we don't really use RAP except for this one application.
Any help at all would be greatly appreciated.
Sean.
This is a dependency-related issue, and has nothing to do with RAP. Nevertheless, be careful that the notion of GEF has changed a bit. GEF4 includes: GEF, Zest, Draw2D. Rather than installing the whole thing, I suggest you download your dependencies (i.e. go to GIT and pull the GEF4 project), and then include those projects (or build them as JARs) and include them to be available at runtime, and of course as dependencies.
I recently updated my ports on my FreeBSD 9.0 release machine and I think eclipse was upgraded due to a port upstream forced Eclipse to be rebuilt. Now Pydev is gone. I tried uninstalling then reinstalling Eclipse, then installing Pydev using pydev.org/updates inside Eclipse. It appears to install ok but I can't create a Pydev project or use the Pydev view. I tried removing my ~/.eclipse folder to force the creation of a new one, and reinstalling Eclipse and Pydev to no avail. What am I doing wrong? I'm running Eclipse Indigo version 3.7.1 build id: R3_7_1
This question was most similar to mine, but the solution didn't work for me. I also tried pointing my install site as: http://update-production-pydev.s3.amazonaws.com/pydev/updates/site.xml per another question on StackOverflow, to no avail.
After some more testing I finally got the newest FreeBSD port to work. I had to launch and install the plugins as root. It didn't work another time I ran it but, this great troubleshooting document helped out. I methodically went through each step one by one, and the logs indicated there was an error on my /usr/local/lib file it was trying to unzip. My user doesn't have write access to that directory but root does. I don't know why it didn't work the last time I ran it as root, perhaps I didn't install the plug-in as root. It works now, so I'm happy. Thanks Fabio, for your input.
I'm not sure how FreeBSD packages things, so, maybe an easy way out would be getting Eclipse from Eclipse.org and installing PyDev on that fresh install (or if you're also doing web stuff, I'd suggest grabbing Aptana Studio 3, which comes with PyDev preinstalled, so, you don't have to worry about configuring it).
See: http://pydev.org/download.html for details
I tried to delete the Eclipse Helios 3.6 with GWT plugins manually as I usually did with other eclipse IDEs but now I faced a strange problem.
A warning window opens which says...
"Cannot delete resources file. Access denied"
So it makes unable to proceed the deleting pressing OK :(
So how to delete Eclipse Helios 3.6?
Any useful comments are appreciated
Unlocker can help see what program has a particular file locked, like joeslice's link, and it can also force that program to relinquish the file handle (which of course could cause bad things to happen in said program so make sure you know what you're doing).
try to start your computer in safe mode:
when you turn on your computer, push F8(5 times to be sure that it'll work) and after choose safe mode.
You'll be able to delete your files
Process Explorer can help see what's got a particular file locked.
I want to share my problem and my final solution...
The problem was because the Eclipse Helios 3.6 internal GWT plugin update error (so the UI Designer doesn't work).
I was trying to update gwt plugins and that made gwt never compile...
So I had to delete it and reinstall.
The reinstallation was OK but since then I tried to download gwt plugin for many times and had the same UI editor error... I think there is a bug in included gwt plugin GWT UI core and window builder.
If someone faces the same problem please read next...
To install GWT for Eclipse Helios 3.6 you should
A) Install GWT UI Designer first from http://dl.google.com/eclipse/inst/d2gwt/latest/3.6
B) Only then Install GWT SDK and gwt plugin (to skip the bugged plugin part to be installed)
otherwise if you start from this link http://dl.google.com/eclipse/plugin/3.6, it will install a bugged GWT window builder and core (the newest one) and won't allow you to install the correct one because "the newest is already installed" so you'll have to delete and reinstall etc... That's a real headache %) So to avoid that follow point A then B.
I hope that will save ones day :)
Good luck
I'm trying to install an Eclipse plugin for Mylyn/Fogbugz, and I get the following error when I try either EclipseBugz or Foglyn:
Cannot find a solution satisfying the following requirements Match[requiredCapability: org.eclipse.equinox.p2.iu/org.eclipse.swt
I'm using Eclipse 3.4.1
what other update sites do you have enabled in your Eclipse installation?
I had similar problem when upgrading from older Mylyn, and found out that it helps to disable other updates sites. When installing new plugins, or even updating old ones, Eclipse has a tendency to contact all enabled update sites. I don't know what exactly it is trying to do, but it helped me to disable all sites except one I wanted to use.
Btw, Eclipse 3.5M6 has option to use only selected update site -- it is great help when updating/installing plugins. I cannot wait to see Eclipse 3.5 final released, just for this feature.
Eclipse plungins require Equinox UI for dependency.Please read Equinox installer .I hope can help you. : )
