Issues with dependencies - Eclipse Java Project -

i have java nlp project (say x) in eclipse has dependencies in maven & jars added externally buildpath.

now i've built ui project(x) using java swing project in eclipse (say y).

when run project y (which calls project x when button clicked) throwing me errors

java.lang.noclassdeffounderror: edu/stanford/nlp/ie/nerclassifiercombiner

which think because, project y not able find/recognize external jar i've added in project x.

i've tried adding external jars project y's build path nothing worked.

can please me figure out how handle these dependency issues. been struggling since 4 days.

thank you.

i faced similar issue. figured out problem maven dependencies not external jar.
in case, did not create main project (i.e. y) maven project why wasn't working. moment converted (y) maven project, code started working magic.

i had add lib folder of project x in project y too.

hope solve issue too.
