When I'm using STS (Spring Tools Suite) 4, the autocomplete stops working for no apparent reason, and the only solution I find is to stop all my work, close the STS and reopen again. But this interruption is extremely annoying.
I couldn't find the cause of the problem. It happens randomly sometime after I start working. The autocomplete screen stuck like the image above showing that "1 pending" and it never finishes.
Version: 4.8.1.RELEASE
Build Id: 202010230733
This sounds related to https://github.com/spring-projects/sts4/issues/579, so please follow up on the GitHub issue with more details. Especially a thread dump of the IDE process as well as the language server process would be extremely helpful in debugging the fixing the issue.
As a workaround, you could go to the Preferences -> Java -> Editor -> Content-Assist -> Advanced and disable the Language Server Proposals. That will most likely help to avoid the problem (but also disables some of the Spring Boot related additional content-assist features for the moment) until we fixed the underlying issue.

I just upgraded to the App Engine 1.7.6 SDK for my python app and realised that breakpoints no longer work in PyDev (Eclipse plugin) when using the new dev_appserver.py.
Does anyone know of a way of enabling them again? I assume the new server is spawning a new process for the web server, and the debugger isn't attaching to that one. I'm not sure how to configure it to do that though.
In the meantime I am using the old_dev_appserver.py server.
UPDATE 2012-07-27:
Following the comment, I verified, the issue is solved after updating to
PyDev. 2.8 and App Engine 1.8.2
OBSOLETE:
I found the following analysis of the problem at googleappengine issues tracker
The reason why PDB doesn't work is because dev_appserver is using
stdin/stdout for interprocess communication. Python has built-in
libraries for IPC: http://docs.python.org/2/library/ipc.html.
dev_appserver should use these, and then stdin/stdout can be left
alone so that PDB still works.
So it seems that there is no workaround, rather than reverting to use old_dev_appserver.py
UPDATE 2013-04-23:
Inability to debug is annoying.
Many developers complain about it

Yep, ran into the same problem.
Open your Run/Debug Configuration and set the Main Module to:
${GOOGLE_APP_ENGINE}/old_dev_appserver.py
Do you mean pdb.set_trace() isn't working?
Look for the function MonkeyPatchPdb() in google/appengine/tools/dev_appserver.py
Run that somewehere in your own project before you use pdb and it should fix it.
On integrating a library on server side of my gwt app (maven, gwt 2.4) the development/hosted mode stopped working. The app works fine if deployed or run with "gwt:run" and all unit tests and integration tests pass as before.
If i start development mode (run/debug as web application) from Eclipse the develpoment mode view pops up but nothing else happens. normally the console should show some output but console keeps empty. So i don't even have a hint whats going wrong.
Can someone give some advice where to look / what to do to get at least a hint what's wrong?
if i check out the revision before integrating the library the development mode works! - at the moment i add the dependency (only adding not using it) it stops working.
Background about library i added (don't know if my problem relates to this):I had some problem on integrating the library. the library uses eclipse birt charting engine. This engine has a dependency to Apache derby db, this conflicted with another library. i solved this by excluding the derby dependency via maven. the second problem was a "command line too long" error on unit test - this was solved by updating the maven-surefire-plugin.
The Problem was hard but the solution is simple: With Java 7 it is working!
The problem could be reproduced on 2 of 3 machines. The machine without the problem is the only one that uses java 7. So i installed java 7 on my machine and linked eclipse to it - now hosted mode (from eclipse) works again :-).
I'm experiencing some weird problems on using web stuff in Eclipse (Indigo, Indigo SR2 and Juno). My proxy configurations seems to be messed when Eclipse tries to do sth on web.
My browsers stop to communicate and I have to restart my machine in order to restore my Internet access again (or close Eclipse and browser and force the browser to reload proxy configurations). In Eclipse, the communication is unstable, working/not working sometimes.
My "NetWork Connections" are set to Manual, where proxy address, port, auth, user and passord are set to HTTP and HTTPS schemas (I didn't use it for SOCKS due to update issues - see this question).
I have no idea of what is happening and why, and how to fix it. Thanks for helping.
It is very unlikely that Eclipse influences your global settings. If anything outside of Eclipse does not work, should look there for the problem first. Eclipse can either use your system wide settings, or it's own overrides.
I understand your frustration - hard to know what is going wrong.. I really don't see what Eclipse can be doing to cause this though. I can suggest some further troubleshooting steps though.
Can you test the proxy config on any other machine?
Can you browse normally on this machine at other times?
Can you go to the same URL in browser that Eclipse is going to?
Perhaps do you have Eclipse checking all sites for updates (Help > Software) and this is just network slowdown?
When you are experiencing this effect, can you ping outside sites?
Im finding after a few weeks of GWT development my Development Mode compilations suddenly slow down at the stage where you see this in the Development Mode console log:
Validating newly compiled units
I've found a related question but this seemed a little vague compared to my issue
Eclipse getting too slow - workspace recreation helped
Since I lose window/toolbar layout settings (even if export/import prefs) and other useful things when I recreate the workspace I want to find out which files I can clean?
I've raised a bug with GWT..
Another answer which really solved it in my case.
Is it possible that you are operating behind a proxy which has to be configured in Preferences->General->Network Connections (e.g. for installing plugins)?
That's true in my case but I had deactivated the proxy settings to reach the in-house SVN. As it seemed, the Validation routine always tries to download ui binder XSDs without success which takes a lot of time.
Concerning my comment in my first answer: yes, it run a lot faster after reinstallation but the reason was that I had to activate the proxy settings for reinstallation. Once I deactivated it again for an SVN commit, it ran slow again ;-)
I have similar problems with Eclipse (Indigo Service Release 1 Build id: 20110916-0149)
and the GWT plugin. Especially when starting Eclipse, Validating the GWT components in my project takes ages.
Googling revealed that the GWT designer in combination with a 64Bit Eclipse Indigo causes this issue.
http://code.google.com/p/google-web-toolkit/issues/detail?id=6602
I wil try to reinstall the GWT plugin without Designer.
Eclipse is constantly running 'Loading Messages' from what appear to be various plugin sites as well as a main eclipse site (all reference a messages.xml file). Is there a way to disable this? They are never able to actually load as I am behind a proxy, so it just sits there and churn. I've yet to find a solution to this.
Edit:
Most of the time, I have my active provider set to manual. This is required on my end in order to access source code. So I actually have eclipse set up to not use a proxy. Because of this, eclipse can not contact any outside sites (but I don't have a choice on this issue). The active provider is only native when set I need to download a plugin for the first time (or manually update etc).
I'm assuming you're using Eclipse Helios (3.6).
Eclipse 3.6 should be able to detect a proxy.
Under Window -> Preferences, General -> Network Connections, you should see all of the proxy entries and the proxy bypass defined.
Make sure you have the Active Provider as Native.
