Persistent cache of compiled HQL queries?

In developing my servlet filter, I created some HQL queries against the XWiki object store. These apparently get compiled and cached somewhere in generated code, because when I had an error in a query, changing it and rebuilding the project had no effect on the query text, so that it evokes the same exception and reports the same query text as before, unless I clean my project every time I change the text of the queries. Apparently the dependency of the compiled queries on my class needs to be stated in a way that it isn't currently. Any clues on how to do this? brain[sic]
