I inherited a program with a lot of //TODO: messages, which i expected would show up under Tasks.
Unfortunately, that pane is empty. Is there a way to refresh it for the current project?
The tasks tags in *.java files are scanned automatically by Eclipse compiler. You can simply refresh your project and then click on the Project / Clean... menu. Also check that task tags are not disabled in the project settings under Java Compiler / Task Tags and your Tasks or Markers view in Eclipse configured to show tasks for an entire project and not only selected element.
There are two different views in eclipse. One is Tasks and the other is Task List. The latter shows build tasks using Mylyn. So for those who are looking for TODO list in java, please open Tasks in General view. Do a project clean if the list is empty.
In addition to Eugene's answer: A simple "Clean" is not enough, you have to build the project too.
(I do not use "Build Automatically", so I have to explicitly check "Start a build immediately" to get the Tasks View refreshed.)
The Clean method suggested by Eugene didn`t work for me, later I figured out that I didn't save the file, after saving it (ctrl+s) the Tasks view refreshed automatically.
If it is the "Eclipse IDE for C/C++ Developers" you are using then "Project -> C/C++ Index -> Rebuild" will do the trick rather than Project clean/build.
Today I was very happy to see the project properties of the Flex Builder 4.5 a setting named "Task Tags". Looking for a long time I found the settings in the Eclipse Preferences under General -> Editors -> Structured Text -> Task Tags.
I thought that I would finally have the opportunity to create tasks with //TODO in my as and mxml files. Unfortunately I did then the second tab "Filter" found. "Scan the Select Content types" is unequivocal and here are the file types, css, dtd, html and xml.
I would now like to add mxml and as, but that does not seem to be possible. Another possibility would be to take the extension of Dirk, is available here.
Here I do not like that I can not create their own tags, and this is possible with the out-of-the-box feature of Eclipse. But not for Flex files.
Can someone help me or how did you solve this?
Thanks and best regards

I'd like to run an external beautifier over my code that's open and replace the contents of the document with the output. Is there a plugin or something I can exploit to do this? I thought it would be a no-brainer under the formatter preferences, but it looks like you can only use internal templates.
One solution is the following:
Create an ant builder on your project. See this article about how to do that. The important things you should know after you read the article:
Add a new ant builder by right click on project and properties. See the implicit variables your ant script will have. The variables will contain one or more resource name and path. So be prepared for collections.
Filter the resouces in the "Build
options" tab. This is important,
since launching a JVM (or a new task
inside IDE JVM) for the change of
every file (filetype) is not so
fast. So filter resources to be
processed like this:
The third thing is to ask eclipse to refresh the resource after the script is run. Like this:
Set the target of the ant script to be run as automatic build (third option). You can set all the four anyway it will be ok:
Write your script. You will find the log of the ant script in console, and you may redirect the log into a file as well. You can see the option on the second picture. Start your script with an echoproperties tag to see what your script gets from eclipse.
I used such builders a lot, it works like it should. I like them. Good luck. Consider accepting your answers, 42 % is not too much :D
I have recently come across the LESS Leaner CSS a template engine for CSS based on ruby. The idea sounded neat, but in practice we need to compile the program to get CSS. This is cumbersome as we make too many changes while working on CSS and for every edit we don't want to compile.
In Eclipse, there are "Save-Actions" but it handles only formatting changes.
Is there a way on saving the file in Eclipse, to call or trigger the compilation?
Its easy to do this in Vi or Emacs.
I think all you need is to define a custom Builder for your project. That way, you can run a program or an ant script whenever certain files change.
Right click on the project -> Properties -> Builders -> New
While the Builders are a good solution, keep in mind they only work when a build is issued - either using auto-build or using a manual build which is invoked, well, manually. If you are looking for something that will operate after a save, regardless of the auto-build state you will need to write a plugin which listens to resource changes in Eclipse.
You do that by creating a workspace change listener and installing it like that:
ResourcesPlugin.getWorkspace().addResourceChangeListener(
..., IResourceChangeEvent.POST_CHANGE);
I'm sure you can take it from here :-)
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.
