I just upgraded this morning to 12.1.4 and now projects that have been working for months will no longer compile. The problem is "java: javacTask: source release 1.7 requires target release 1.7". I've googled this and found that I have nothing under File/Settings/Compiler/Java Compiler/Additional command line parameters, it is blank. Also, adding a "-target 1.7" or a "-source 1.7 -target 1.7" does nothing to rid the problem.
Any suggestions, please?
