I have been using Eclipse for a few years and everything was fine. But a few days ago, something must have happened, because the code completion broke.
The problem seems to be only related to 1 workspace to a specific project and only to classes from this project.
The suggestions show up just fine, but upon confirming they are not inserted into the code.
I've tried the whole Preferences>...>Advanced to default, closing and opening the project, rebooting Eclipse and switching to a different workspace and back, but the problem persists.
EDIT0: For clarification, autocomplet works fine in another workspace, another project or when using java's own features (such as System.out.println())
EDIT1: Having the error log open, I noticed a new error appearing every time completion failed, here is the full trace

EDIT2: I've downloaded a fresh Eclipse, the problem persists, it also seems to apply to classes from a linked library, copying the code to another project doesn't help either.
EDIT3: It suddenly started working again, I have no idea why, I'm unaware of changing anything other than hand-writing more code in my project.
I just started developing desktop application which can communicate to libreoffice of linux using libreoffice extensions.
I am trying to run Github LibreOffice Extension Code Sample.
Its showing error "Editor could not be initialized" and log below.

I tried creating some sample project using File->New->Project->OpenOffice->Extension Project. Still getting those same error below.
Also I tried this and this but still no positive result.
Any help would greatly appreciated.
Thanks
Error was due to project was runnning as LibreOffice Extension.
To solve the issue I created a new configuration with name LibreOffice Application (Instead of extension). Its running smoothly now.
I'm getting the following error:

Some background information: I'm running eclipse kepler 20130919-0819, os x 10.9.1, google suite plugin 3.5.1.
Deployment now does not work on any of my projects. I recently updated the plugin and there was a message that it required java 1.7. Development was working as usual after that message and I had no problems until I tried to deploy. (When I change the java compatibility on the project I get an error that GAE required 1.7.)
This may be related to the problem I'm having with java. According to mac preferences, java 1.7 is installed yet when I start a terminal session and issue the java command to check the version, it indicated 1.6. eclipse also seems to be running on 1.6 and I can't figure out how to rectify this. It may or may not be related.
My question is: can I fix this problem in place or do I have to back out updates and reinstall? I can continue to develop but am unable to deploy until I have a solution.
Thanks in advance.
Thanks to Rajeev, I have a lead but the problem is not fixed yet.
So I find the keplar eclipse.ini file. There is no -vm entry. It has the following contents:
/System/Library/Java/JavaVirtualMachines is 1.6.0.jdk. I assume that this is where eclipse is picking up the jvm.
So I find and add an entry in the .ini file following the pattern in eclipse wiki:
I get the following Alert:
Then I go to the Mac Java Preferences which says that java is 1.7 is installed under:
/Library/Internet Plug-Ins/JavaAppletPlugin/Contents/Home/bin/java
This is where java gets installed when you go to java.com to install.
Then I get:
So this is like an adventure game, but not as much fun.
I see that I have to update the .ini file, but where or how do I get the right java?
My Eclipse cannot show the editor window.
Error:
Could not open the editor: The editor class could not be instantiated.
This usually indicates a missing no-arg constructor or that the
editor's class name was mistyped in plugin.xml.
Notes:
I'm using different Eclipse (and not plug-ins) for C++ and Python - and they work flawlessly, it's just the java eclipse that is causing troubles.
I've already tried re-installing eclipse, and even reinstalling java. any idea?
It has no troubles displaying the project file, it's "just" the *.java and *.class files that cannot be opened.

EDIT 2:
I changed the workspace and it fixed the problem (for the new workspace at least) but still - no idea why it happened. (though I am still curious, so I leave this question open).
This is often a problem with temporary files saved by eclipse plugins.
Check YOUR_WORKSPACE/.metadata/.plugins/org.eclipse.jdt.core/.
There are a lot of index files. Sometimes it helps to delete them.
Also, start your eclipse with -clean.
But I think your problem is slightly different.
Did you have a reference to a library(jar-file) somewhere in your filesystem?
If you deleted it or moved it, eclipse can't build your projects.
Did you refresh all your projects?
I've got the same problem though my eclipse is much newer - 4.2 (Juno). For me the solution was to remove <workspace>/.metadata/.plugins/org.eclipse.core.resources/.snap. Afterwards I found this bug in eclipse.org: Bug 178988 - Crash at startup due to ".snap" files.
Hope this will help somebody.

The stack trace seem to indicate that there is a problem with your classpath.
Maybe your JRE is pointing to an invalid location / isn't defined? (Window->Preferences->Java->Installed JREs).
Maybe your project contains invalid class path entries? Try to create a new java project and check if that is working as expected. If it works check the classpath of your not working project.
Edit: Another Idea ... launch eclipse on an other workspace. Then create a launch configuration for an "Eclipse Configuration" with the workspace that produces an error. Set a java exception breakpoint for NullPointerException. Start in debug mode and you can inspect the variables to see which path produces the problems.
Google this error and you get plenty of hits in a variety of (Eclipse) IDE's and plugins. There seems to be no record of real 'fix' though, besides the one you found out where you create a new workspace.
3.6.2.r362_v20110210 is the version I'm running. Are you sure you're on 3.6.2? You're first edit lists
-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.2.R36x_v20101222
which seems to point at an older release.
I agree with another poster that you should definitely search and/or post this on Eclipse's bugtracking system. That's the least you can do when you use open source software.
I tried a couple of options
delete cache files within .plugins
delete all index files in <workspace>/.metadata/.plugins/org.eclipse.jdt.core
delete snap file in <workspace>/.metadata/.plugins/org.eclipse.core.resources/.snap
-clean as a start up parameter
-initialize as a start up parameter
But I keep getting the error back randomly.
So far, the only option that worked consistently is removing the .snap file, the first time we launch eclipse after removing .snap file it works fine.
Also any time we launch it in a new workspace; it works fine. but we would hate to switch the workspace for this reason.
Moreover if we close and relaunch eclipse the issue comes back randomly.
I was getting this for FlashBuilder 4.7. It was a permissions issue. On Mac OSX, from the info box, I gave my user READ & WRITE access to Flash Builder 4.7 folder, then did "Apply to enclosed items..." and that fixed it.
The solution to the above problem is to go to
workspace.metadata.plugins\org.eclipse.jdt.core & remove all the index files.
Thanks FlorianOver
Had the same problem(on Indigo 3.7) and getting right version of jadclipse jar(net.sf.jadclipse_3.3.0.jar with Jad 1.5.8g) did it for me
Removing the index files as suggested by others didn't help in my case. I had to reset the perspective: right-click the "Java" perspective toggle button in the upper right corner, choose "Reset". At least it's better than recreating the entire workspace.
For me it worked to delete workspace/.metadate/.lock and then restart by using eclispe -clean -refresh
Here was simple. Right-click in the class and choose the / open with / Java Editor, or Generic Text Editor option.
Aqui foi simples. Clique na classe com o botão direito e escolha a opção / open com / Editor Java, ou Editor de Texto Genérico.
When I faced this issue. I simple updated the eclipse and it resolve the problem.
A solution which worked for me (after first unsuccessfully trying the other more accurate steps listed above) was to do as below:
Close Eclipse and delete all the contents of {Workspace}.metadata.plugins folder.
Open Eclipse. It does not show any projects.
Import the projects into the workspace by going to the File menu, clicking import and continuing with steps.
The issue gets resolved this way. However, a drawback is that you have to import the projects again after the steps.
I faced the same issue. It was basically caused by a version mismatch of the jadclipse jar. Initially I had jadclipse_3.2.1.jar but then I updated to net.sf.jadclipse_3.3.0.jar. Resolved the issue.

I replaced the freemarker jar in plugin directory and I am using clean option also .. but couldn't find anything...
FreeMarker is a bit old (latest release in December 2008).
Can you check you reproduce the problem with eclipse Ganymede 3.4(.x), that is older version, or eclipse 3.5.1 (more recent)?
SWT might have evolve in non-compatible way since then. Or it might just be an old bug still un-resolved (like the 115253 one, or the 287886, which should have been fixed in 282218, but for Mac and probably only in 3.5.1).
There's no mention of Freemarker classes in the above stack trace. What editor are you using?
I have Eclipse 3.5.20090621-0832 and Freemarker IDE 1.1.0.M1-N200906060434-H241 and both are working fine. Freemarker IDE is part of JBoss Tools.
You can get the latest development milestone (stable releases only support Eclipse 3.4.2) - note that it requires Eclipse 3.5.1 / Galileo SR1.
Or, if you're using Eclipse's built-in package management, update site is here along with installation instructions
Just encountered the same problem and tracked it down to:
<style type="text/css">
<?php ?>
Basically, it seems like, this Exception is thrown b/c the parser is confused by certain combinations of HTML and PHP.
I can have this Exception thrown just by creating a new PHP-file and fill it with something like that. But the odd thing is it seems like after playing around with it a while makes the Exception disappear. So maybe it's a Unicode-thing neutralized by my editing after a while.
Anyway, there you go.
Best
Raffael
