JavaScript validator throws NullPointerException in Eclipse

Question

I'm coding some PHP files on Eclipse IDE, and I keep getting an error that says "Building Workspace has encountered a problem" -- Workspace is the name of my project area.

When I click on the "details" link I get this

Errors occurred during the build.
Errors running builder 'JavaScript Validator' on project 'Ullman'.
java.lang.NullPointerException

As mentioned, I'm working in PHP so I don't know why it's trying to set up JavaScript Validator. I can't figure out how to stop it from doing these things. Anyone know?

I'm not experienced, so please provide a detailed answer if you can.

Answer 1

I just ran into this problem myself and the previous accepted answer was not helpful. The problem is not the validator, it is the build. To fix go to Project -> Properties -> Builders, then disable ‘JavaScript Validator’. Since you are working with PHP your build is getting confused when you try and validate a PHP file with a JavaScript validator.

The error message doesn't really do anything it just gets annoying really fast.

UPDATE: Cleanshooter's answer is the better one for PHP-specific projects. I'm leaving this answer since it is useful for people who run across the error on JavaScript files because of crashes in the JavaScript parser.

You can disable part of the JavaScript validator with Eclipse -> Preferences -> JavaScript -> Validator -> Errors/Warnings and unchecking Enable JavaScript semantic validation
