[tycho-user] java.lang.NoClassDefFoundError when executing outside Eclipse

We use tycho to produce our Eclipse maven builds. We create a product (eclipse-repository) and use a target platform (eclipse-target-definition). The  problem that I'm having is after the tycho build in Eclipse, I can successfully run the app using the "Launch an Eclipse Application" option from within Eclipse, but when we attempt to run the generated C:\<proj_dir>\com.sma.em.product\target\products\com.sma.ui.em.product\win32\win32\x86\EnterpriseManager.exe from the command line, I get the following exception:

What could be the cause of the issue? I've attached the product file (EnterpriseManager.product) and the product pom file, as well as the main configurator pom.xml

Attachment: EnterpriseManager.product
Description: EnterpriseManager.product
