The EU military leaders are watching Ukraine closely (as is any other competent military leader anywhere in the world) and trying to figure out how they will handle this problems. The EU is also talking to Ukraine military leaders and brainstorming solutions that Ukraine is trying in real time (not all military leaders are, but a lot of countries outside of the EU are). The EU is also designing new weapons/systems with the current situation in mind, it is likely that these (whatever they are - this is classified but I can say it with confidence anyway because it is so obvious there is no way they are not doing something) will be ready before Russia attacks.
