Why can't I search maven projects in eclipse - eclipse

I'm using the m2Eclipse plugin (http://m2eclipse.sonatype.org/) to handle maven modules in eclipse. After enabling a project for dependency management and for nested modules, I can no longer do a 'File Search' over the project. The search finishes instantly with the search window display "0 matches in empty scope".
Any ideas how I can make search work again?

It would appear the plugin marks any non java folder as 'derived', which is why it gets ignored by the search. Right clicking on the non java folders and deselecting the check box fixed this.

Small addition to #slashnick’s answer:
In the “File Search” dialog of Eclipse you can also use the checkbox “Consider derived resources” to search those “derived” resources. This may be more convenient if you don’t want to change the properties of multiple resources just for a search.

How to restore Eclipse last project tree expand on startup?

When I quit Eclipse some interesting packages are opened. But when I restart Eclipse all projects/packages are collapsed.
Is there a way to save the state of the Project-Explorer on closing Eclipse?
I don't want to use the Link to Editor feature, because this allways opends packages, that I don't want to expand just for looking up some declaration in an other class.
I also don't want to use the focus view of MyLyn, because I want to be independent of a task and want to see all available packages.
Is there a build in feature of Eclipse to do so?
I found in a Eclipse-Issue that this feature was removed, because It took to much time in the startup-phase. So this feature does NOT exist in Eclipse without an additional plug-in.

InstaSearch (eclipse plugin) functionality in intelliJ v11.x?

One thing I miss about moving from eclipse to intelliJ is the InstaSearch plugin that would let you to search the source code codes of your entire project very quickly, really simple and effective.
Is there such a functionality in intelliJ either baked in or added via a plugin?
IntelliJ supports search and replace in your entire project.
To find a text in all files within the specified path
1. On the main menu, choose Edit | Find | Find in Path, or press Ctrl+Shift+F.
2. In the Find In Path Dialog, specify the following options:
Text to find (you can select one from the recent history drop-down list).
Search scope (project, module or directory).
Search options (case sensitivity, whole words, and regular expressions).
See instructions here.

Eclipse PDT Builder - What is it? How can I disable it?

I have a custom build-script for my site. I want to invoke this script whenever I press ctrl+b in eclipse.
I have configured a new builder seen at the top. While my own builder runs fine, eclipse also invokes "Validation" and "Script Builder". As far as I can tell these two do absolutely nothing, but take ages to complete.
I have tried to simply disable them, but eclipse just creates them again as another instance. (hence the duplicates)
I have tried to add an exclusion to * for the PHP Build Path, but that didn't do anything.
What do "Validation" and "Script Builder" do exactly? Why do they take so long and above all: how can I disable them?
The fact that these two builders are re-added after you disable them is a bug. Please file bug reports at bugs.eclipse.org. You will need to file separate bug reports as these two builders are maintained by different groups of people.
The Validation builder performs a variety of validation on artifacts in your project. You can see all validation that's performed under Validation property page in the same dialog. In that page, you can selectively disable the categories of validation that you don't want.
The Script Builder comes from PDT and presumably performs validation on the actual PHP artifacts. Outside of what you've already tried, I don't know of a way to disable it.
2 years later and I have the exact same problem with latest PDT.
This is what I did:
Validations:
Right-click project
Properties
Validation
Click checkbox "Enable project specific settings"
Click checkbox "Suspend all validators"
Script Builder:
Right-click project
Properties-
PHP Build Path
remove all folders from "Source folders on build path:"
or remove all but the ones you really want to be checked for syntax errors
Now "build" phase of PHP project is way shorter (like a half a second :)))
However, if you want to be able to navigate PHP source using Eclipse (like right-click on function and select "Open declaration" or pressing F3 on function name) then you need to leave folders in Script Builder with source you want to navigate. I had project with huge folders containing source of various frameworks and I removed those from "Source folders on build path:" and only left folder(s) with project source. That cut down build time to second or so.

Eclipse content assist (for PHP or anything) not using active working set

The Eclipse content assist for PHP (and I'm assuming for other types as well) isn't using the currently active working set - it's searching ALL files in the project. How do I change it to only use the active working set?
When doing a Ctrl+Shift+R search, it was also looking for all files in the project (not what I wanted), until I clicked the small black triangle in that window and selected the working set I wanted it to use. Now it successfully only shows the files that match my search string in the working set. However, this doesn't change anything in the autocomplete content assist feature (i.e. doing a Ctrl+Space to complete the name of a function or variable). Is there any way to accomplish this?
I'm using Eclipse Indigo release, so it's very recent.
I'm afraid it's not possible the way you put it. Eclipse Working Sets just give you a way to organize your projects.
However you may want to take a look at Mylyn, which is fully integrated with Eclipse platform. Here and here is a nice overview of what you can do with Mylyn. But briefly, what it allows you to do is to create a task and maintain a context associated with it. This way, only the relevant files will be displayed in Project Explorer and autocomplete would suggest you only task-focused options.

Excluding/Disabling Validation in Eclipse

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.
