Normally when you put the '.' after an object and wait you get a list of methods/fields/classes that one can access. My eclipse no longer does this for me. I spent 10-15 minutes searching for a way to turn it back on and I came up empty. How can I turn this back on?
You can try mucking around in
Preferences > Java > Editor > Content Assist
and see what you get. I've had this once before; eclipse got into a bad state and wouldn't code complete for a given project. Reverting changes in the project got rid of some errors and it started working again.
Assuming you're using Java you need to look at setting Java -> Editor -> Content Assist. You want to make sure that "Enable auto activation" is checked and the other options are set to your taste. The auto activation trigger should be the period.
It may not work if you have an error in your code.

I am using the latest version of Eclipse (4.3) and every time I go to use the dot operator it shows the same options every single time. Here is what it shows.
As you can see it only displays things such as "create new object" which does not make any sense for an import. Can anyone explain why this is happening and show me how to get it back to normal?
You can check and activate the available autocompletion suggestion providers via Window > Preferences, Java > Editor > Content Assist > Advanced.
Okay, so my issue is when I am creating a variable, lets say for example "Object o" while I am typing "o" it'll suggest something like "object". Which is okay but when I press space it auto fills in the new name. Basically I don't want to turn off auto completion I just want to disable space auto filling the suggestion in. Even to disable variable naming suggestions would work.
I'm using Eclipse Juno Service Release 1.
I know it's an old question but since non of the answers here worked for me, and this problem was really annoying me too, I am adding solution that helped me.
In your Eclipse go to:
Window/Preferences/Java/Editor/Content Assist
and enable:
Disable insertion triggers except 'Enter'
screen/shotted
Hopefully that will work for everyone!)
As there isn't any definitive solution for this yet, what I find works best is to disable the alphabetic characters from triggers:
Windows > Prefereces > Java > Editor > Content Assist > Auto activation triggers for Java
This will mean no class name / type completion, but method name completion will still be suggested when you pressed dot, however at least Eclipse stop messing with my variable name
Go to Window/Preferences/Java/Editor/Content Assist and choose settings that works for you.
I realize this is a 3 year old post, but...
From what I can gather, there isn't an option to disable this, it was hard coded into the content assist feature. But there is a plugin that you can download from the answer to this stack overflow question that will disable this feature
Window -> Preferences -> Java -> Editor -> Content Assist -> Advanced
I turned off Java Type Proposals and made sure Java Proposals is turned on. By the way this is in Spring Tool Suite I haven't checked using eclipse.
is it possible to set a timeout for the Eclipse function hint list?
Waiting for the full function list to load simply pisses me off...:(
First, you can trigger the content assist immediately by hitting Ctrl-Space.
Second, you can set the delay under Window->Preferences->Java->Editor->Content Assist->Auto-Activation. Non-Java editors may have separate settings. You can type search terms on top of the prefence window to see all related settings.
I would like to add on this by pointing out that I was facing the same kind of issue in Eclipse Mars Version 4.5.0 M1.
I got this error :
I managed to solve it by disabling the following setting "Code Recommenders proposals" from Window\preferences\Java\Editor\Content Assist\Advanced
Disable it from both Default proposal kind and Content cycling . Restart eclipse , and the error is gone.
I don't know why this happens, or what the addon does. Maybe someone can elaborate on it.
I develop Java code with Eclipse and regularly get this message:
resource is out of sync with the filesystem.
Right-click > Refresh will always clear this.
But why can't Eclipse refresh automatically when it finds this condition? Are there cases where you want the resource to be out of sync?.
If there are such conditions and they don't apply to my work, is there a way of getting Eclipse to refresh automatically when it encounters this state?. (I appreciate that it should refresh as little as it needs to in normal development to increase performance for human developers.)
UPDATE (2012-06-25):
My latest update (Version: Indigo Release Build id: 20110615-0604)
no longer shows
Preferences - General - Workspace - Refresh Automatically
There is an option "Refresh on access" - should I use this?
You can enable this in Window - Preferences - General - Workspace - Refresh Automatically (called Refresh using native hooks or polling in newer builds)
The only reason I can think why this isn't enabled by default is performance related.
For example, refreshing source folders automatically might trigger a build of the workspace. Perhaps some people want more control over this.
There is also an article on the Eclipse site regarding auto refresh.
Basically, there is no external trigger that notifies Eclipse of files changed outside the workspace. Rather a background thread is used by Eclipse to monitor file changes that can possibly lead to performance issues with large workspaces.
Just right click on the file or on the project and click Refresh. The error will vanish. I also faced the same issue and it worked for me.
Window -> Preferences -> General -> Workspace
For the new Indigo version, the Preferences change to "Refresh on access", and with a detail explanation : Automatically refresh external workspace changes on access via the workspace.
As “resource is out of sync with the filesystem” this problem happens when I use external workspace, so after I select this option, problem solved.
This happens to me all the time.
Go to the error log, find the exception, and open a few levels until you can see something more like a root cause. Does it says "Resource is out of sync with the file system" ?
When renaming packages, of course, Eclipse has to move files around in the file system. Apparently what happens is that it later discovers that something it thinks it needs to clean up has been renamed, can't find it, throws an exception.
There are a couple of things you might try. First, go to Window: Preferences, Workspace, and enable "Refresh Automatically". In theory this should fix the problem, but for me, it didn't.
Second, if you are doing a large refactoring with subpackages, do the subpackages one at a time, from the bottom up, and explicitly refresh with the file system after each subpackage is renamed.
Third, just ignore the error: when the error dialog comes up, click Abort to preserve the partial change, instead of rolling it back. Try it again, and again, and you may find you can get through the entire operation using multiple retries.
If this occurs trying to delete a folder (on *nix) and Refresh does not help, open a terminal and look for a symlink below the folder you are trying to delete and remove this manually. This solved my issues.
When you open an Eclipse workspace from within a clearcase view and try to rename the project, you will often get the pop-up warning ... “Resource ‘project’ is out of sync with the file system”. If refreshing the project does not fix the problem, then do the following workaround: a. Open workspace WITHOUT being in a view b. Select the project in Project Explorer c. ClearCase -> Associate Project (project should now look like project [] ) d. Right click project -> Refresh (vob sub-folders should now be empty) e. Right click project -> Rename ... f. Enter New name
Now you can close the workspace, reopen it in a view and refresh the project. You may also dissociate the project if you prefer the project not to be associated with the vob.
A little hint. The message often appears during rename operation. The quick workaround for me is pressing Ctrl-Y (redo shortcut) after message confirmation. It works only if the renaming affects a single file.
If you are a regular Eclipse user than you might have got this error many times. The error simply says, “you’ve made changes in files in your workspace from outside eclipse”. The simplest solution would be to select the project and press F5 (Right click -> Refresh).
if you need more explanation you can read from this web site
I was not able to resolve this error by either refresh or by turning on "native polling" workspace feature. Turned out my project was also opened in two instances of eclipse. Once I closed the other instance, the error went away. So make sure your project is only opened at one place if you are seeing this error.
If you press Shift+Ctrl+T or choose "Navigate > Open Type..." you get the "Open Type" dialog for quickly navigating to a known class. When you start typing a name only the classes for which the name matches stay visible. That way you can find a class of which you know the name very quick without having to browse through the package explorer tree.
This has been working great for me up until this morning. All of a sudden for a couple of my projects I am only seeing some of the types that exist. Of course I tried the obvious steps of refreshing the projects, cleaning the projects, re-building the projects, rebuilding the projects externally, but all to no avail. It is a bit odd since the types are known in other places. If I add an import statement Eclipse does not complain that it doesn't know the type and I can Ctrl-Click through the types to get to their file. However, the type navigation knows nothing about them.
In the past when InteliJ used to do this to me I would go find its cache files and delete them forcing it to rebuild. Does Eclipse have something similar I might do (I'm an Eclipse newbie)? I am using Eclipse 3.4.2 and I have it configured to not delete files on a clean (because our actual build process puts files into the output directories that I don't want Eclipse mucking with).
Have you tried closing and reopening the project? Only types from open projects are held in memory, and the refresh occurs when you Shift+Ctrl+T for the first time on a newly opened project.
Edit to add: Ctrl+Shift+R also displays the types (along with everything else) but it also supports the Camel-case thing to find the Java types quickly.
Close eclipse and delete any .index files and the savedIndexNames.txt file in workspace/.metadata/.plugins/org.eclipse.jdt.core once eclipse is restarted it will rebuildl the entire index for Ctrl+T
try starting eclipse with the -clean flag, you can add this to your eclipse.ini which can be found in the same directory as you eclispe.exe, or if you start eclipse using a bat or shell script, add it as a startup argument, e.g. eclipse -clean.
The clean will tidy your workspace, and should force eclipse JDT to recalulate types. Ive had issue with .snap files (with seem to be created on dirty shutdowns) that seem to corrupt my workspace until I clean them up, not long ago eclipse lost the Object class!! made for some interesting errors!
I get problems like this often. I tried your solution, noticed it seemed to rebuild its search index, but I still couldn't find any of my classes. Then I took a look at the little green arrow on top right corner of that dialog, and noticed I had a working set selected which belonged to another project. I find it a little dumb that Eclipse doesn't warn you about this or anything, since this can be a very annoying little detail that one tends to forget (me at least ;-)).
Anyways, clicked on "Deselect Working Set" and bam I can find my classes again. Thought I'd add this here since others may make the same mistake.
This worked for me -
Select your project in Package Explorer
Press F5 or Right click and select Refresh
I used the "-clean" as first line in the eclipse.ini (version Juno) and worked like a charm.
I'v tried all the answers and I still had the issue. I then tried this:
I deleted the project (it's a maven project) and re-imported it. This time I made sure i check the "Add Project(s) to working set" checkbox. After that Eclipse was able to find the classes in that project.
The problem must have started because I didn't check this checkbox when i first imported this project.
By the way, I'm using Neon
(Warning: Shameless marketing ahead)
If you like this feature, you would love nWire. nWire allows, among other things, to quickly search not only for types, but for any possible Java element like method or field. It also uses a navigator view which is non-modal. After searching you can see the class associations in a very quick and easy way. Check out the video on our site.
