Jaspersoft Studio plugin in Eclipse Mars 2

I am using Eclipse Mars and I have a web project built in Java 7 with reports in jasper, I installed the JasperReport Studio 6.6.0 plugin in Eclipse and when I make changes in some report I compile it using the plugin and when I go to display it from a page of my application I get the error Unsupported major.minor version 52.0 and that's because the plugin works with a higher version of Java, in this case Java 8. I would like to know if I can change a parameter or a configuration in the plugin that will help me use the same Java version for the whole project and not have a mismatch.
