Liferay source classes cannot be resolved

[Thomas Trieb, modificado 7 Anos atrás.]

I'm currently trying to write my own iFrame portlet (so it can be preconfigured and the users can't mess with it), but the classes from Liferay's source code (I have imported the portal-master project) cannot be resolved.

I'm fairly new to Liferay so there's probably some configuration I have overlooked. If anyone could point me in the right direction, I'd be very thankful.

Please post more details about classes which you are not able to use in your portlet.
