I've just installed Eclipse Helios 64bit but when i try to install Acceleo, te download seems endless and Eclipse seems blocked.
Is there someone that can help me?
Thank you
The very first install of anything in a new Eclipse tend to be extremely long (Eclipse usually contacts all of its available update sites and checks for update on every single installed plugin before doing anything).
Within a new Eclipse and with a lot of update sites available, the longest I've seen it take for a single install was about 10 minutes. You can usually check whether Eclipse is actually doing something by opening the "Progress" view (Window > Show View > Progress).
I am one of the member of the dev' team of Acceleo and I am always working on a 64bits Eclipse with a 64 bits virtual machine and there are no problems. If you are experiencing this problem it is because of a timeout of the update site. Right now, it is the release of the sixth milestone of all the Eclipse projects so the server tends to be overloaded. You can try it again or just wait a few hours. If you absolutely want Acceleo today, you can always download the zip version directly from here.

I am using an Eclipse IDE for Java Developers version 2019-12 (4.14.0). As there were no JSP support, I went to Eclipse site and drag and drop the install button to my eclipse. It started the installation but even after hours it stuck around 80%.
I restarted the Eclipse and even my machine but as an when I click on the Marketplace, the dialog shown in the image comes up and stuck there. The cancel button also doesn't work.
Please help..
For JSPs, you actually want https://marketplace.eclipse.org/content/eclipse-enterprise-java-developer-tools, but if you keep running into this issue, it sounds more like a problem with your network.
To rule out any issue with it being on the client, you can add https://download.eclipse.org/releases/latest into your Available Software Sites preference page, Check for Updates from the Help menu, and then try the directions at https://wiki.eclipse.org/WTP_FAQ#How_do_I_install_WTP.3F. If everything else fails, the downloadable package at https://www.eclipse.org/downloads/packages/release/2020-12/r/eclipse-ide-enterprise-java-developers is an option (for the next week, after which 2021-03 will have been Released).
I have an Eclipse Kepler IDE where ADT Plugins, CDT plugis, Android NDK and Java is installed. It is sort of my lifeline IDE at work. Without this my whole work will come to a standstill. I have this IDE installed on a Vbox Ubuntu machine and have been using it for the past one year(ever since the glorious JUNO version days!). About 2 months ago, my IDE was veyr slow so I upgraded it from Juno to Kepler expecting better performance. I must admit it was not any at all. Also, on my VBox, the IDE froze a couple of times whenever I plugged in a USB in my Virtual Box. I assumed it must be some bug with the USB and just left it. Today, all of a sudden (this is the 5th time I have rebooted my virtual image) whenever I tried to copy a piece of code in my IDE, the whole IDE freezes. Only a kill -9 pid number command came to rescue after that. What should I do? Please suggest!!
thanks a lot.
First, you should configure the Java VM to create a thread dump when Eclipse hangs. Eclipse doesn't just hang for the fun of it; something is wrong but since there is a deadlock, Eclipse can't tell you anymore. Read up on debugging deadlocks.
The next step when Eclipse is acting up is always to clean the .metadata folder since a crash sometimes corrupts important files in there. See this blog post.
If that also doesn't help, you can try to reinstall Eclipse. Install the plugins one after the other, noting down what you do until you find the one which breaks the others.
I do C++ embedded development for the NetBurner platform. They have plug-ins that customize Eclipse and in addition to a build tool-chain they add a Launch Group under the Run Configuration area. Everything was working fine under Indigo (32 bit) when I decided to install Subclipse (big mistake). As soon as the install finished I could no longer run my existing configurations successfully. When I went into the Run Configurations area I noticed the Launch Group I used to use was missing. Here is what it looked like earlier yesterday:
Here's what it looks like today:
Things I've tried
First I uninstalled the Subclipse plugins using the
Help->About->Installation Details and then selecting them one at a
time, Uninstalling and restarting after each uninstall. No change.
Then I unpacked the original Eclipse Indigo/CDT 32 bit download to a
fresh folder. Copied over the NetBurner plugins from the zip I got
from the manufacturer. No change.
Launched with different Workspaces, no change.
Launched a Galileo version, it uses older plug-ins, and it still
works.
Copied older plug-ins into Indigo, the older NetBurner launcher
shows up (but it doesn't really work with Indigo)
Removed the older plug-ins put in the newer ones, old NetBurner
launcher went away new launcher does not show up.
Tried removing the
{Workspace}.metadata.plugins\org.eclipse.debug.core.launches - no
change.
Interestingly even though launches has many .launch files that should show up under Run Configuration, nothing shows up.
One other strange (possibly relevant) thing is that icon for the NetBurner Perspective went away, now it just has <NetBurner> as the text and a generic perspective icon.
I can still cross-compile and build for the NetBurner (i.e. the build toolchain still works), it's just the ability to use run configurations that seems to be missing.
I'm out of ideas, does anyone know of some global setting that sits outside the workspace and outside the Indigo installation folder that could be causing this?
I'm running on Win 7 64 bit ultimate, I run the 32 bit version of Indigo because the 64 bit doesn't appear to work with the NetBurner plug-ins. I've also disabled the two Mylyn tasks under General->Startup and Shutdown (they seemed to cause many Permgen memory crashes). This is the same setup I had working flawlessly yesterday.
Update
I also noticed that only 3 of the 4plug-ins are showing up in the Installation Details plug-in pane. The nbeclipse.core_2.6.0.jar is in the eclipse plugin directory but not showing as loaded. So I guess I know now the problem is the plug-in isn't loading but I don't know why or how to get it to load, or what subclipse could have changed that would cause this.
I suspect that the Subclipse installation may have caused an update to some other plugin(s) that it depended on (keep in mind the transitive nature plugin dependency resolution; if you're installing plugin A and it requires a certain version of Plugin B that you don't have, Plugin B will be installed or updated to that version). In doing so, maybe the NetBurner plugin can no longer load because its declared dependencies are no longer met (ie, it depended on an earlier version and does not tolerate a later version).
You can use the OSGi Console to help determine why a plugin is not loading. Here are a couple of references that should help:

By the way, you can not just copy plugins into an Eclipse installation and expect them to work. For several versions now, Eclipse has not supported that ability. You must use Help > Install New Software or File > Import > Install > From Existing Installation to install plugins. Ask the vendor if they have an update site to install from; like I said above, simply dropping things into Eclipse's plugins folder is not supported any more, it won't work. Other than the vendor providing an update site, the only other option is to use the dropins folder, as described here.
This is a bit of a repost but the solutions proposed in the posts I found previously did not work for me, so I thought I might just as well start a new discusion.
I have a new Eclipse Indigo and I want to install the GWT-Plugin. I am running java Runtime Environment build 1.7.0.01 on a Windows OS (64 bit). The Eclipse is also the 64 bit version. I execute eclipse as administrator (but the same problem pops up if I don't).
Eclipse is told to juse java 1.6 as a compiler (since I hear there are issues with 1.7 and GWT).
So I click Help>>Install New Software and put in http://dl.google.com/eclipse/plugin/3.7 as a source. This then takes forever (Fetching Children of GWT) resulting in:
"Unable to read repository at http://dl.google.com/eclipse/plugin/3.7/content.jar.
Unable to read repository at http://dl.google.com/eclipse/plugin/3.7/content.jar.
Read timed out" as an error.
I have tried this all day. Once I at least could read the repository but could not install because of some unsatisfied dependencies. But that was on another eclipse distribution if I remember correctly.
So generally I don't seem to have any luck with GWT.
I would be greatfull for any advice to get GWT running. thanks.
Edit googled further, found a blog entry that told me to update to java 1.7.0_04. did that. no change.
Edit2 On the assumtion, that it is in fact not my eclipse but the google servers, I used the download of the plugin (as sugested by kush in the comments). This gets me to this screen http://i.imgur.com/0qV1v.png but not that much closer to the solutiuon.
"Cannot complete the install because one ore more required items could not be found."
I have tried this with Indigo and Helios, the ruslts are similar.
This took a while (three days) but the answer is as easy as it is strange: Do not use the 64 bit version of eclipse.
I would apreciate if someone finds out what the problem with the 64 bit versions is, but as soon as I started using the 32 bit version (which works fine on the 64 bit windows) everything installed perfectly.
Anyway, hope to help somone else with this post.
I have been struggling with this issue for days now. I cannot get the GWT eclipse plugin installed on my laptop. I am using the 32 bit version of eclipse. Plus, I can install the plugin just fine on the 64bit version of Eclipse on my PC, so I know that is not the issue.
Finally! I solved this.
Had to completely uninstall JRE 7 then everything installed fine.
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
