java - Google App Engine's SDK compiles JSPs to class format 52.0, too high for server -

i'm facing problem eclipse , app engine sdk building jsps class format 52.0, subsequently fails deploy server accepts java 1.7 classes.

i've seen bunch of workarounds tell me utilize 1.7 jvm start eclipse. however, not possible due corresponding client application heavily using java 8 features.

is there way eclipse either:

compile jsps using 1.7 class formats? or, failing that, utilize 1.8 compiler, runtime, , rt.jar suggest for, build, debug, , run standalone maven project?

java eclipse google-app-engine
