Change Eclipse settings to ignore errors on a specific file

In my dynamic web project in eclipse, I have jQuery in my js source folder. For some reason, Eclipse is not handling it correctly and interpreting many lines as errors in the standard jQuery file (even though I have the javascript development tools installed).

Can I turn off the error checking on the jQuery file (and that file only)? I still want it to detect errors as usual, but ignore anything in jQuery.js.

It looks like eclipse has changed a bit,
but the following method which worked for me seems very close to the old one.

The solution consists of 2 steps:

1. First you have to update Eclipse's preferences (Window > Preferences):

Make sure that you check both Manual & Build next to the Validator you need
(in my case - a javascript one).

2. Last you should change your project's Validators:

Click on Client-side JavaScript Settings (or any other validator you need):

The explanation is clear but basically what you should do is as follows:

Click on Add Exclude Group..., select it and then click on Add rule....
Then pick Folder or file name (note that there are other options), and specify your file/folder.

You should be able to verify that its working by deleting the existing errors/warnings,
and then left-click your project and select the Validate option.

This setting can be committed into source control as well.

Perform these steps to solve this(This will disable eclipse validation for Javascript):

1. Go to Eclipse > preference > Javascript> validators > Errors/Warnings
2. Uncheck "Enable JavaScript semantic validation".

If you have messed around with the javascript settings in your projects, then restore everything to default first for all the projects that u have changed. After that, follow the steps.

I had javascript errors seen on jquery mobile file on an Android Phonegap project. I simply removed the file from the project and add it afterwards. It works now.

One way is that : 1.remove javascript -> validator -> errors/warning. 2.remove project -> .project file -> javascript command 3.It is important,too! delete js file and import again.

With eclipse Luna I was getting this as well. I did a right click on jquery.jqGrid.min.js and selected 'Validate'. It then validated fine and the errors went away.

Not sure if it'll work for all. But what i did was select the unnecessary errors in 'problems' tab of eclipse, Rclick and Delete. Eclipse stopped showing the error..
