Seems Eclipse determines that there is something wrong with JQuery and refuses to deploy a web application containing it. The work-around is to give up validation of JavaScript, specifically with two steps:
- Turn off automatic build, go to Navigator view for your project, open the .project file and remove the following line: <nature>org.eclipse.wst.jsdt.core.jsNature</nature>
- In project properties go to Builders and de-select the JavaScript Validator
