JSP don't work on Windows with Gretty

Hi everyone ! I’m currently trying to migrate my ANT project to Gradle. It’s a web-app project and I’m using the gretty plugin with Tomcat 8 to make it works. Everything was going seamlessly on my Linux desktop, but for some reason, my JSP throw an exception if I try to run my project on Windows. My imports cannot be resolved. It’s exactly the same project and I’m using Netbeans with boths OS.
