i'm running into following errors everytime i start eclipse. If i move my project to a new workspace, everything works fine for the duration of one session - as soon as i open eclipse for the next time, the same thing is popping up again.
I tried various suggestions i found in other posts (closing/reopening project, validation, cleaning,etc.) without success. Here is my stacktrace from the last session (its too long to post it directly in here:))
The main symptom is that Tomcat doesnt start - it is stuck at 7%.
Thank you guys in advance, your help is highly appreciated!! If you need anything else, just leave me a comment and i i'll post it!
Your Eclipse environment is seriously messed up. Perhaps you installed plugins the wrong way or you used the wrong Eclipse or plugin version.
Trash everything. Delete the Eclipse program folder altogether. You can keep your workspace folder, but you should delete its .metadata folder. Now download a fresh copy of Eclipse for Java EE (note, with the EE!), extract it and then integrate Tomcat again the usual way by the Servers view. Note that you don't need any additional plugins for this step.
JBoss Tools should be installed via Help > Install New Software. You should specify the JBoss Tools update site matching the exact Eclipse version. Currently it's Indigo SR2, so you should specify http://download.jboss.org/jbosstools/updates/indigo/SR2/ as URL.

I was developing a plugin, using Eclipse IDE for java developers (Version: 2021-09 (4.21.0)
Build id: 20210910-1417)
During development, when I run it as an eclipse application, it opens a runtime-Eclipse application where the plug-in is present. In my setup this new runtime-eclips app opened from a folder next to the workspace, where C codes were present. (and my progrem would get the tests run in C , and get the results from it's exe)
Then I downloaded the Eclipse IDE for committers, which is a newer version. I downloaded it as a zip and after unpacking I run the eclipse.exe. My program had problems opening the runtime-Eclipse application in C there, so i went back to the older one which is installed on my computer.
After opening the original eclipse, on which I was working and had no problems, I was hoping everything will be fine. It opens the IDE for java developers (same version, same build) but I have the same problems with the runtime-eclipse application as the one I run as an eclipse.exe , (not recognising the C code?? I don't understand).
When i try to run the plug-in I get this error.
And when the runtime-app opens i get this error.
I cannot create C projects anymore on the runtime-app. I don't know the reason behind this.
Also I have billion of these
["java.net.UnknownHostException: downdload.eclipse.ort"]
[" org.eclipse.equinox.p2.core.ProvisionException: Unknown Host: http://downdload.eclipse.ort/eclipse/updates/4.2/content.xml "]
Thank you in advance!
I don't know if it is possible or not, since seemingly it did not update the older eclipse IDE. If it can be restored the way it was before i run the eclipse.exe, I would be happy.
eclipse.ort is obviously a typo, it should be eclipse.org, I don't know where it is coming from - but its possible you enter it yourself as update site
the runtime error means eclipse cannot resolve all dependencies, which means it could not load bunch of plugins including yours, you need to figure out why on your own, its not possible to debug this remotely, its best to start from the scratch in the new workspace
The solution was easier than expected. The run configuration was modified by the other eclipse version. It was not launched with every plugin. only a selected handful
I have an eclipse plugin which runs fine in the eclipse version i'm using for developing it. It basicly also runs fine if i export it and install it in a fresh keppler version.
My plugin contains a New Project wizard to create projects which can be used with the plugin.
Now if i used this wizard in my development eclipse if i click finish, everything runs fine the project is created and the dialog is closed.
If i do the same in the fresh keppler installation, the project will also be created and everthing seems to be correct but the dialog won't close until i hit cancel.
Now i really wanted to come up with more information but in the development environment there is no exception occuring.
Also when i start the fresh keppler one with the -debug option i won't get an exception if i hit finish().
Any ideas what could cause this problem or how i could get more information on this?
It is always worth looking in the .log file in the workspace .metadata directory when something unexplained happens to see if something has been logged.
In fact it is worth checking the log once in a while during plug-in development just in case something has been logged.
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 am currently working with a product that is built onto Eclipse version 3.4.2.
I am trying to install the jaxb builder plugin, but it is not working.
So far I have tried:
Unzipping the folder into the Eclipse plugins folder and then restarting Eclipse
The restarting Eclipse using the -clean flag
Unzipping the folder into the product's (built onto Eclipse) plugin folder and then restarting with and without -clean
Unzipping the folder into the dropins folder and then restarting Eclipse
I think that it may be possible that this version of jaxb builder doesn't support my version of Eclipse, but I can't figure out how to find that information. I tried emailing the address on the "Contact Us" page, but it came right back to me.
Is it possible that the product has been discontinued? How can I find out?
Discontinued? I don't know but the last build is from 2011-05. It's built against Eclipse 3.4 (see plugin.xml). What do you mean be "not working"? Exceptions? Entries in Eclipse error log/view?
Turns out it was the application's fault. I'm not exactly sure what the problem was, but when I did the exact same thing in a regular Eclipse environment, it came up with no issues.
I will edit if I get more information.
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
