Eclipse Design Tab detects wrong Java -

-

when click on design tab error:

incompatible java versions  eclipse running under 1.7, java project has 1.8 java compliance level, windowbuilder not able load classes project. use lower level of java project, or run eclipse using newer java version.

i've checked in window>preferences that:

  1. >java>compiler set 1.8
  2. >java>installed jres has 1.8 jdk default

have missed something?

looks java_home set java 7 one, require restart?

you're executing eclipse java 7, can update java_home point java 8, , restart eclipse (not computer).
