自动javascript版本控制以避免浏览器缓存清理

Question

My web application uses a bunch of javascript files and I want to version them as and when different releases of my app are out. This is so that the users do not have to clean the cache everytime I publish a new js with my release.

Example for version 0.0.5 for my app I want all my js to be inside app/js/0.0.5/common/ etc

I am using maven. But have no clue how to automate this kind of versioning. I know one thing for sure, will need a replace plugin to replace all tokens in my jsps to the right version number at build time.

You can force browser not to cache files that may update in future like this:

<script src="/app/js/0.0.5/common?nc=<generate unique string here>"></script>

so src will be different every time so browser will not cache this script
