I made a build of one of my plugins a few weeks ago and it gave me detailed analysis but now it just says the build failed with no logs... Is there something wrong with building process? (My plugin compiles fine)

Could you provide a little more details, ie. which plugin?

Edit: It looks like the unnecessary hard dependency on Playtime Tracker was causing it to fail; changed that to the appropriate dependency level and now it is working fine. Not sure why yet, but Calytic is looking into that.

@Slydelix As per the documentation, "hard" dependencies are only used in special circumstances.  I changed your dependency to a normal dependency and your plugin built correctly.

I didn't understand it correctly, thought I only had 2 options - optional and hard, I guess not chosing any sets it to "normal" :P
Thanks for clearing this up :D

There are 3 options: Required, Optional, and Hard; not setting any defaults it to Required. Setting it to Hard makes sure that the CI uses it for compiling.
