Javascript Validator problem in Eclipse

Posted: March 4, 2011 in Eclipse

This is a problem that has happened to me on some Web Dynamic projects. Every time the project is built, I get this error:

“Errors occurred during the build.
Errors running builder ‘JavaScript Validator’ on project ‘some-project’.
java.lang.NullPointerException”

At a first sight it seems that a Javascript validator is throwing a NullPointerException, so probably you will try to disable ‘Client-side Javascript’ validation from Project->Properties->Validation… but I tell you that the problem is not there, you must go to Project->Properties->Builders then disable ‘Javascript Validator’.

Problem solved. Indeed is not a real problem, but the message is a bit annoying because it happens in every build so….

    Fuck Eclipse and their JavaScript Validator. It’s worse than useless.

      Ha ha very well said!!!

      Yup. An error message modal dialog that comes up every 30 seconds and means nothing is why Eclipse designers should be kept on a very short leash. The message give no hint as to where the problem is, and no hint of how to suppress it.

      It is only through the power of crowd-sourced IQ points that I can use Eclipse at all.

    • jahbini says:

      Amen. Error messages like this are worse than useless. Like a ball and chain for developers.

    I got alot of following errors after change to new eclipse.
    Syntax error on token “-”, ArrayLiteralHeader expected after this token
    Syntax error on token “/”, delete this token

    i did as what you suggested. No luck for me.

    • I think that has nothing to do with disabling Javascript Validator on Builders config. The solution I proposed is not for disabling Javascript errors or so, it’s only for the NullPointerException I mentioned in the article.

      wordcount_cleanregex’, /[0-9.(),;:!?%#$¿'"_+=\\\/-]*/g
      use this exp and no need to worry about these false errors….
