Eclipse not updating, something blocking connection? - eclipse

While updating software in Eclipse using menu 'install new software' , the program stops when connected to updateServer
Installing software: Fetching oracle.eclipse.runtime.glassfish_3.1.0.0.jar (3,93kB of 78,33MB at 0B/s) from ... well, I tried several and it just stops
I tried running eclipse as administrator
I tried without firewall
I tried on a clean eclipse install
somehow something is blocking
what have i been missing

This is usually linked to some kind of proxy issue, as illustrated in bug 330877:
Pick one of the default sites that came pre-installed with eclipse in the drop-down at the top of the box.
Progress window says "Fetching children of Helios" (or whatever update site you're trying).
It grinds for a few minutes, gets to 50% progress, then pops the error dialog.
Repeat with any other update site you can think of, watch them all fail.
OK - I found the issue - this is on Windows XP, and the IE network
configuration had a hard proxy setting that was throwing Helios off.
The weird part is that this didn't seem to affect Ganymede or most of my other apps.

How do I disable Spring Dashboard on startup on GGTS?

I recently installed GGTS. It's been good so far but it's starting to annoy me how the dashboard (window) keeps showing up on start up. I checked the preferences but there's nothing there that switches it off. I attempted to uninstall the feature, but the GGTS won't allow me.
You are probably running into this bug: STS-3935. The dashboard is supposed to stay closed when you close it, but in some situations in STS 3.6.2 it doesn't.
If you upgrade to a newer version of STS the problem should go away. If you do not want to upgrade your STS, you can also try running with JDK 8 (so you'll get the new dashboard which is not subject to the bug).
Or, another workaround suggested in the bug-report is to open manually edit the preferences file at workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.springsource.ide.eclipse.dashboard.ui.prefs and add or change the line:
org.springsource.ide.eclipse.dashboard.uidashboard.startup=false

How can I debug why eclipse won't start?

I've been having trouble getting a weblogic server to run in eclipse, which have resulted in me not being able to open eclipse ni my current workspace at all. It is not my first attempt to work with weblogic servers in eclipse, and I do not know why it suddenly decided to stop working. I have had multiple errors, which all seem to be related to an abnormal high memory consumption.
One of my last errors, before eclipse quit on me for good, was an out of memory exception, on PermGenSpace. I set variables to 1024m, but it still complained it wasn't enough. After a lot of restarts, Eclipse suddenly wouldn't open my current workspace. I have tried others, and they work fine, but with my current one, the splash/loading screen disappears after about 10% of the loading bar is complete, and nothing happens at all. Except the fact that eclipse.exe shows up in the running processes tab on Windows task list. It does not show in the running programs list.
My attempts to start weblogic servers had the exact same symptoms. They showed in the process list, but did not respond when I tried to open the console in my browser.
Both eclipse and the weblogic tasks (shown as java.exe) has had over 400.000KB of memory consumption each, which I find very high.
I do not expect anyone to be able to find a complete solution here, but I am absolutely stuck. I cannot access any of my previous error messages. I have no experience debugging an error like this. Does anyone have any idea on how to find the error in a case like this?
My Weblogic version is 10.3.2, which is a company standard for now.
My Eclipse version is:
Eclipse Java EE IDE for Web Developers.
Version: Kepler Service Release 2
Build id: 20140224-0627
Adding the comment as an answer since it provided some help.
Try starting up to a new empty workspace; If you dont get to select workspace at startup use the argument "-data " If you still get issues, look at the log in /.metadata/.log

Eclipse / CCS Bug - Uses All Memory On Clean Project

I'm having a problem with CCS6, which is based on Eclipse. I'm trying to build a demo project that comes with a TI MSP430 demo board. When I build the project CCS/Eclipse proceeds to clean the project, during which all the memory on my system is slowly consumed. After memory usage reaches 100% Windows declares that CCS/Eclipse is having problems and asks to close it down.
I am running Windows 8.1. I have uninstalled and reinstalled CCS several times, versions 5.5 and 6.0. I get the same behavior every time. I also updated the version of Java on my system. I have reached out to TI support engineers and they are baffled and useless. I have also tried with a second computer also running Windows 8.1, same behavior.
The problem is obviously rooted with gmake somehow. Perhaps there is something wrong with the project files causing this behavior? I haven't experimented with other projects yet.
Thanks!
P.S. I wanted to post screen shots but StackOverflow isn't letting me. The window I see in CCS/Eclipse is titled "Cleaning selected projects" and then reads "Invoking Command: c:\ti\ccsv6\utils\bin\gmake -k clean" And it just stays on this forever. Using Task Manager I can then see my memory slowly filling up. After about 5 minutes or so it reaches 100% use and Windows asks to shut down CCS.

Eclipse Indigo is unable to read repository (update sites)

First of all this question has been asked at least twice.
I tried several approaches with no effect.
Here's the problem:
When I try to download/update plugins like EclEmma, Eclipse starts to communicate with the repository and that takes about 5 minutes. After that I get an error:
"An error occured while collecting items to be installed
session context was:(...)
Unable to read repository at http: (...)
Read time out
(... for every *.jar)"
What I was trying to fix the problem was running eclipse as an admin (got vista x86 running) and changing the connection properties from native to direct and back. I also tried deleting saved repositories and adding again. No effect at all.
I have no proxy configured and don't need one.
This is getting kind of personal between me and my IDE :D
So I hope you guys can help me out.
Thanks Zoltán (köszi :D), but i found the error last night.
Resolution
After hours of debugging I figured out that AVG Anti-Virus Software blocks the request. After deactivating it for temporarily, Eclipse installed the new software.
In my case timeout was caused by definition of SOCKS proxy... we have proxy.company.com:80 and I incorrectly provided that proxy to all three (HTTP, HTTPS and SOCKS) connection schemas. Removal of proxy from SOCKS resolved the problem
Try to open the internal web browser of Eclipse (Window menu/Show view/Other...), and navigate to the 1) update site url, and 2) to any webpage.
If the latter one is not working, then Eclipse does not have connection to the internet, and you should try to open a new workspace, and try installing from there (possibly something wrong in the workspace settings).
If the second one works, but the first one does not, that suggests that the update site is not working. In this case report to the developers.
I also had this problem (my system: Win7, jdk7, Eclipse Indigo).
I installed jre6, changed my JAVA_HOME, ran eclipse with the following:
eclipse -debug -consolelog -vm 'c:\Program Files\Java\jre6\bin\java.exe'
Install the plugins/updates, then switch back to using jdk7.
Worked for me!
Temporarily disabling AVG firewall fixed the issue for me.
Eclipse then installed the Android plugin.
In my case, adding these lines to eclipse.ini solved the problem
-vmargs (this one was alreayd there)
-Djava.net.preferIPv4Stack=true

Unable to read repository at http://download.eclipse.org/releases/indigo

I was trying to add the PDT,
Indigo - http://download.eclipse.org/releases/indigo
Unable to read repository at http://download.eclipse.org/releases/indigo.
Unable to read repository at http://download.eclipse.org/releases/indigo.
http://download.eclipse.org/releases/indigo is not a valid repository location.
So what's the correct url ? I went and looked lots of places. Can someone point me to the exact link ?
Edit :
Problem once you go to http://download.eclipse.org/releases/indigo , you will see the below error. So I guess its moved somewhere.
This software repository URL, http://download.eclipse.org/releases/indigo/ , provides access to the software repository for the Eclipse indigo release. Until its released in June 2011, it will contain milestone builds.
The repository site URL is typically pre-populated in the list of software repositories when you install the Eclipse Platform or SDK.
For more information about installing or updating software, see the Eclipse Platform Help.
There is also a collection of handy, downloadable all-in-one zip files available for many interests and platforms. Many people find these all-in-one packages the easiest way to get started.
Can you connect to internet at all through Eclipse?
Open the internal webbrowser. In Eclipse: Window -> show view -> Other -> General: Internal web browser.
Look up any normal adress, is it working?
Can you connect to another update site? Try for example Eclipse Emma:
http://update.eclemma.org/
Do you see anything there?
What are your proxy preferences? Go to Window -> preferences -> General: Network connections.
The active provider:
Specifies the settings profile to be used when opening connections. Choosing the Direct provider causes all the connections to be opened without the use of a proxy server. Selecting Manual causes settings defined in Eclipse to be used. On some platforms there is also a Native provider available, selecting this one causes settings that were discovered in the OS to be used.
If internet is working fine outside of Eclipse, try changing to Native. After that, try Direct.
I have encountered problems where an update site would not load, then I had to remove it and add it again. This forces Eclipse to reread the contents of the site even if it has a cached copy. So, if you still get no connection to the indigo update site, but everything else is working, try that. Go to Window -> Preferences -> Install/update: Available Software sites. Then remove and add the indigo site. Just remember to copy the adress so you can add it again.
As suggested in a comment below by #lostiniceland, this is a simpler way to achieve the above:
Goto Window -> Preferences -> Install Update -> Available Software Sites => select the entry and click the "Reload" button to the right. This is sometimes also helpful when you have a local updatesite for testing custom plugins
I had the same problem and resolved it by
Deleting the cache directory \eclipse\p2\org.eclipse.equinox.p2.repository\cache
Refreshing the repositories.
Preferences -> Install Update -> Available Software Sites => select the entry
Click the "Reload"
Check if you are able to connect to eclipse market place url (http://marketplace.eclipse.org/) from browser. If its working then the issue is because of proxy server using in your network.
We have to update eclipse with proxy server details used in our network.
Go to :- Windows-> Preference -> General -> Network Connections.
And edit HTTP ,with proxy details.
Click OK
Done.
I was having this problem and it turned out to be our firewall. It has some very general functions for blocking ActiveX, Java, etc., and the Java functionality was blocking the jar downloads as Eclipse attempted them.
The firewall was returning an html page explaining that the content was blocked, which of course went unseen. Thank goodness for Wireshark :)
Another way to solve this kind of error is to start eclipse with this argument
-vmargs -Djava.net.preferIPv4Stack=true
Working fine with Eclipse (x64) 4.3.1
Had this problem in Linux, and I found that the user doesn't have permission to update the eclipse directory
change the owner of eclipse folder recursively, or run eclipse with user who has write permission to the folder
In Windows 7 32-bit version, I started the eclipse with as an administrator. This worked for me.
I had the same problem. Try to deactivate your Firewall (I had avast!), which worked for me.
(Sorry for my English I'm French :D)
Please make sure you are using correct url. If You are using url - http://download.eclipse.org/releases/indigo on your eclipse luna(v4.4) then it might be not working in this case you should use - http://download.eclipse.org/releases/luna
I have tried this and its working.
What worked for me:
Since yesterday, I have been trying to install the Eclipse plugin - "Remote System Explorer" from the Eclipse marketplace on a freshly downloaded Eclipse 4.8 as shown below,
and everytime I was getting this error:
Unable to read repository at http://download.eclipse.org/releases/kepler/.
Unable to read repository at http://download.eclipse.org/releases/kepler/201306260900/content.jar.
download.eclipse.org:80 failed to respond
which brought me to this SO post.
I tried a few solutions mentioned here in the different answers like this one and this one and this one, but none of them worked. I just gave up almost, thinking that either the corporate network here is somehow blocking the specific download requests or the 4.8 version of Eclipse is buggy.
Discovery:
I could not reload all the paths under 'Window' -> 'Preferences' -> 'Install/Update' -> 'Available Software Sites'.
Preconditions:
What did work for me from the beginning was:
I could open google.com from the internal web browser of eclipse and,
some of the update paths, I could reload even. (As was mentioned as a possible solution or test, in some of the answers here, like this one.)
Finally, this answer put me on the right track - for my specific case, at least. Just my step was to do the exact opposite of what that answer was doing.
Solution:
I had to change all the http:\\ paths to https:\\ and suddenly it started to work. I don't know who - either IE/Edge on Windows 10 or the Windows 10 firewall or the company firewall is blocking HTTP communications. But with HTTPS, I can finally install plugins from the Marketplace.
HTTPS reload works
I must say, what is strange is that not all the paths required https. Except a few, the rest seemed to have had no problem working with HTTP. But I anyways changed all to HTTPS, just for good measure.
Then reload all the repositories one by one. Press "Apply and close".
Then check for updates. Eclipse will update itself successfully now.
Restart after update.
Finally you can install whichever Plugin you would like to from the Eclipse Marketplace.
Note: In case during the update, this same error pops up again, then see in the repositories that any new paths added by eclipse during the update, are also HTTPS and not HTTP.
Kudos to #Fredrik above. His answer didn't work for me, but lead me to the resolution of my issue:
In 'Window'|'Preferences'|'Install/Update'|'Available Software Sites'. The location that I was attempting to install from the 'Marketplace' was getting inserted with an https:// URL. Editing this to http:// allowed me to then use 'Help'|Install New Software ...' to select the repository from the drop down 'Work with:' combobox instead of having the https:// one automatically inserted and used.
For eclipse, there are normally different options available:
If you want to use the PHP development environment (only), you should go with the corresponding distro of eclipse. There is a distro for PHP provided by Zend.
You may add PDT to an indigo release by doing the following steps:
Check if an update site for PDT is included in your eclipse installation:
Open the Help > Install New Software dialog.
Click there on the link Available Software Sites.
In the list, the URL http://download.eclipse.org/releases/indigo should be marked.
Close the dialog.
Select from the Work with list the site with the right URL.
Enter in the filter box PDT and search in the list for the PDT tooling you want to install.
Install the PDT tooling.
If that does not work, you may download a complete update site from the PDT project site.
Visit the site (URL above).
Click on downloads.
Search there for the string "all in one update site".
Download the zip file.
Install it in your Indigo installation. Help > Install New Software > Add... > Enter name and select from button Archive the zip file
I hope some of the installation instructions will work for you.
This is the correct URL. Chances are Eclipse cannot read it properly because of the Internet connexion.
Are you using a proxy to get Internet access? If this is the case you need to notify Eclipse via the "Preferences/General/Network Connections" menu.
That URL works fine. The message you report is normal when you look at it in a browser. My copy of Eclipse has no problems talking to it. If yours does, I suspect a proxy configuration error in your copy of eclipse.
Also try it by turning off the firewall, and similar services. It worked for me!
If you can't access https://dl-ssl.google.com/android/eclipse/ simply
try to use http://
instead of https://
I spent whole my day figuring out this and found the following. And it works great now.
This is basically an issue with your gateway or proxy, If you are under proxy network, Please go to the network settings and set the proxy server settings(server, port , user name and password). If you are under direct gateway network, your firewall may be blocking the http get request from your eclipse.
I was also unable to read the repository. Even after the disabling most of the entries under Available Software Sites things were still not working.
I had no proxy to worry about and even disabling the firewall (which I do not recommended) as a last resort did not help.
Viewing the error log, from the dialog box which Eclipse displayed, there was mention of a cache directory under .eclipse in my home directory. I deleted the two cache directories I found and Eclipse was working again.
For my setup the two directories I deleted were:
.eclipse/org.eclipse.platform_4.4.2_119745494_macosx_cocoa_x86_64/p2/org.eclipse.equinox.p2.core/cache
.eclipse/org.eclipse.platform_4.4.2_119745494_macosx_cocoa_x86_64/p2/org.eclipse.equinox.p2.repository/cache
NB: My setup is Eclipse Luna 4.4.2 running on Mac OS X Yosemite 10.10.3
In my case, I discovered that the major issue why my eclipse won't connect to internet is my Internet Service Provider. I was only able to browse some websites but unable to browse other website. Fixing the issue with the ISP worked.
My issue was the Eclipse Marketplace client needed updating.
After trying Fredriks solution of
Go to Window -> Preferences -> Install/update: Available Software sites. Then remove and add the indigo site. Just remember to copy the adress so you can add it again.
The Marketplace client wouldn't load. But I could access it via a browser.
So, I went to the Help -> Eclipse Marketplace
it loaded fine
Clicked on Installed and found the Eclipse Marketplace Client and it had so i clicked it it updated and then when I did the standard update everything worked.
Sometimes, there will be firewalls and restrictions in the network preventing the plugin to get downloaded. We can try some other network. This actually resolved my issue.
I was facing the issue while adding team explorer plugin to eclipse from https://marketplace.eclipse.org/content/team-explorer-everywhere.
Used team explorer plugin for ecplise for internal use of xamarin for mac.
Error:
unable to read repository at http://marketplace.eclipse.org/content/team-explorer-everywhere
org.eclipse.equinox.p2.core.provisionexception unable to read repository
Unknown host exception
Goto https://github.com/microsoft/team-explorer-everywhere/releases
Download: TFSEclipsePlugin-UpdateSiteArchive-14.135.0.zip
From Eclipse->Help->Install new software.
From Add Repository window select Archive select the downloaded zip file.
Continue installation.
Also try if in the eclipse paths there is some duplicated
Luna - http://download.eclipse.org/releases/luna
Luna - http://download.eclipse.org/releases/luna/1234567...
Try both of them, one may work.
In my case, with 2 eclispes installed, in one of them the path
Luna - http://download.eclipse.org/releases/luna
works, in the other one, i must select:
Luna - http://download.eclipse.org/releases/luna/123456...
In both the internal browser can access to internet. Both are Luna (but one is RCM, the other one i don't remember).
No meu caso era o anti-vírus que estava bloqueando a conexão do eclipse, desativei o anti-víruse tudo funcionou o//.
Translation:
In my case it was the anti-virus that was blocking the connection from eclipse. I disabled the anti-virus and everything worked.
