this is very weird.
im using jdk and set my language level to "7.0, Diamonds, ARM, multi-catch etc."
however, when im building my project, it still keeps complaining about: " error: diamond operator is not supported in -source 1.5 [ERROR] -> [Help 1]"
is there anything else i can try to fix this? i managed to modify the .idea/misc.xml file to remove jdk-15="true" and it doesnot work.
