I had a folder that contained a lot of projects, and imported them into Flash Builder/Eclipse.
I want one of these projects, and I'd like to remove the irrelevant projects from the workspace.
If I remove everything but the project I want, I get errors in the one I want, so it must have been dependent on something.
However, I have no idea what this project is dependent on. How do I find out?
First, close all your projects (select all, right click and then close). Then, select the project you are interested in and open it. You will be asked if you want to also open the dependencies. This will allow you to see what's needed. You can then delete the projects that weren't opened.
Flash Builder and Eclipse both give the option to close unrelated projects. Simply right click and select "Close Unrelated Projects". Delete those that were closed.

I have read the other posts asking the same question but was unable to get my code to work. I have deleted my meta data and imported my files back in to no avail.
I have my workspace inside my dropbox folder to allow me to code from home or while away. Currently I am using my laptop which is not my primary coding machine. The project worked yesterday on this laptop however.
any help would be much obliged, I will provide any information that is required
First go to the Project menu and select "Clean...". That might solve it right off the bat.
If not, next you should right click on your "src" folder and select "Build Path" -> "Use as Source Folder". Then Clean again.
Try those two things and then report back with results.
Alright, this has caused me enough grief. The answer may be dead simple, but I need some help.
I figured it would be simple to open an existing project in Eclipse, but I'm having quite a time actually making this work. I don't want to change where it's located. I don't want to pull a bunch of strings to get Eclipse to point to it. I just want to take the project directory from where it is now and open it in Eclipse.
Is there any way to do this?
Not sure that I entirely follow, but here's my general routine for creating projects in Eclipse.
I go to File > New > Project and
pick out what sort of project I
want, and hit Next.
I enter the name I want to use for
the project, and the path where I
want to store it. I never store
stuff in my workspace folder.
For projects with existing code, I
just put the path to the existing
folder, and Eclipse just imports the
code.
Hoping that answers your question, but if not let me know.
Probably a very straight forward solution here, but can't seem to find an answer. I recently changed my eclipse workspace to my dropbox folder, so I can work on my netbook when in college and on my desktop when at home. I copied and pasted all my project folders from the old workspace into the dropbox workspace, changed the workspace location in eclipse, but none of the projects are showing up in the project explorer now. Having refreshed the project explorer many times now to no avail, is there any way to add these projects into the project explorer? Thanks
From the main menu bar, select File > Import. The Import wizard opens.
Collapse or click + in General > Existing Project into Workspace and click Next.
Choose either Select root directory or Select archive file and click the associated Browse to locate the directory or file containing the projects.
Under Projects select the project or projects which you would like to import.
Click Finish to start the import.
I have had this problem in many versions of Eclipse and followed the process outlined by #vijin-paulraj, but frustratingly kept failing...
Until I noticed that the checkbox at the bottom of the wizard "Copy projects into workspace" is checked by default, and does not have an eventhandler attached to it. So if you do not clear this box before selecting the directory it will tell you that "Some projects cannot be imported because they already exist in the workspace." Clearing the checkbox after this will not trigger a form refresh and the Finish button will remain disabled.
TIP: once the checkbox is cleared, select the directory again will trigger form validation and allow you to proceed.
Try importing existing project:

The answer for me was to make sure that I was in the correct working set.
I was in the working set from training and had not placed my new project into a working set at all.
While the above answers will most likely place your project into Eclipse, a working set will exclude you from seeing any project that is not placed in it from the package explorer.
My personal answer was to create a new working set to keep it separate from work, via the context menu from the upside down triangle at the top left of the package explorer.
Yours may be to modify your current set by adding the new project to it. This option is also located in the same menu.
My circumstance could have been avoided in the "new project" wizard, if I had placed it in a set from there.
I hope this has been useful. Please, feel free to ask for clarification.
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.
I have the (mis)fortune of having a large project source-base in which I am working primarily on PHP and JavaScript. I have to have the full project area as the project root in Eclipse, but unfortunately this includes several directories that drive the validation built into WST/DLTK/etc. nuts.
I have tried disabling all validators in the project properties. I have gone into the validators one at a time and added rules to the "Exclude Group" set to exclude the specific folders. I have removed the folders from the PHP build path in the project properties. And yet, my Problems view/tab is still littered with thousands of red flags that stem mostly from a folder that we use to keep copies of external elements (Apache, PHP, etc.). You know, typical "have a copy of the specific versions we currently use" sort of thing.
The signal-to-noise ratio is so bad that I'm unable to use the view at all, which is a shame. If I'm not going to have the benefits of the IDE, I might as well be using vim for this (I use it for other stuff, but for this codebase a good IDE is a better choice, providing I can get it to work). It seems to me that it would be an obvious feature to be able to right-click a folder in a project and select "Exclude from Validation", but alas there is no such feature. Is there another way to get the validators (PHP, HTML, etc.) to ignore the folders I need ignored?
Tried solution;
Right click project
Select properties
Select validation
Check Enable Project specific settings
On the XML Validator row, click the '...' button
Select Exclude Gruop
Click Add rule
Select 'Folder or file name'
Click Next
Select files or folder which are not validated.
Click Finish
Click OK
Click OK
This solved my problem. Because eclipse validation gives error for generated GWT files.
Best regards.
I came upon this question while looking for the same answer. I will list the steps I did here and hopefully it will help someone in the future.
I am using Eclipse 4.1 and I do the following to exclude validation for specific xml files. I am sure if you configure the different validators it will work for other files as well.
Go to Preferences -> Validation
Find the Validator you wish to change and select settings (not all of the validators have settings, hopefully yours do).
In the settings you can add an Exclude Group where you can add a rule to specify to exclude the validator for specific extensions, folder or file name, project nature, facet or content type.
I have Eclipse for PHP Developers and I was dealing with the same issue.
In addition tot he excellent answers above, I have one more suggestion.
My first recommendation is not to use Aptana unless you actually want those validators (as they are nearly impossible to turn off from my experience).
Beyond that, go to File -> Properties -> Builders, and deselect "Validation" and "Script Builder" and "JavaScript Validator".
So far it's helped speed up some operations tremendously.
I also recommend disabling "Automatic Build". Because you're using PHP, the odds that you actually need it to build anything if you don't want validation is slim.
In the main menu, go to Project and uncheck "Build Automatically". You will want to build your project every now and then by right clicking on the project and selecting "Build Project".
All the above steps have helped me get the basic editor, which is exactly what I wanted.
I used to exclude resources from validation via project specific Exclude Group (as the most answer here suggests). But in case anyone is still having problems with disabling validation for a specified folder in 2014 - just mark the folder resource as Derived:
This should disable validation for that folder.
If you are using EGIT you might also want to disable automatic inclusion of derived resources in .gitignore:
It is not really possible to select a directory, at least under Windows.
After having pressed Preferences->Validation->Settings->Add Exclude Group->Add Rule->Folder or filename->Browse Folder->(selecting some directory)->[OK]
The "Browse for folder" dialog is being closed, with the "File or folder" field staying empty.
I had the same problem with the web app i'm developping.
I ended up disabling automatic build, and building once a day (Project->Build automatically), that way i still get the benefits of code completion from libraries, while speeding up the program on older computers.
I found in the project properties there is a Builders category. In the list of builders I had a JavaScript Builder. I deselected this builder and all my annoying javascript validation woes went away.
this worked for me:
Properties > Builders section and unchecking the corresponding box. https://bugs.eclipse.org/bugs/show_bug.cgi?id=317833
seems to be a bug in some versions of eclipse.
There are more gloabal validation parameters. You can suspend all validation (or only the ones you don't need) by going to:
Window > Preferences > Validation.
Here, check the box "Suspend all validators".
Alternatively, uncheck the validators you don't need from the list below.
A full build will be requested which might take some time. But Eclipse will run a lot faster afterwards [But without validation of course]

Solution.
Go configure what's displayed in the Problems View like lothar proposed, create new custom filter and in "Scope" area choose "On working set". Now press the button right below this option to configure what working set would it be: in working set selection pop-up hit the "New" button and mark all your project files EXCEPT those you want to exclude from validation. You might want to save this working set under convenient name, like "No_Validation_Set".
Summary:
1) working set excluding problematic files.
2) custom Problems View filter to operate on this set.
Issues:
when adding new files to project you need to update your working set, so they are validated too.
When I excluded files from validation for the project, my setting didn't seem to be recognised until I restarted Eclipse and cleaned the project.
