The kendo scripts distributed are minified and compressed in order to reduce their size. The minification also clears any new lines present in the scripts. This results in roughly 100 000 symbols on a single line. I am certain that this confuses Eclipse.
I am not an Eclipse expert, but it seems that a similar problem occurs with jQuery itself. You can check this Stack Overflow thread for suggestions on how to resolve it.
All the best,
