java - Run a JAR file from the command line and specify classpath -

-

i've compiled jar file , specified main-class in manifest (i used eclipse export function). dependencies in directory labeled lib. can't seem straight answer on how execute jar file while specifying should use lib/* classpath.

i've tried:

]$ java -jar -cp .:lib/* myjar.jar ]$ java -cp .:lib/* -jar myjar.jar ]$ java -cp .:lib/* com.somepackage.subpackage.main

etc...

each gives error saying:

error: not find or load main class ....

or gives noclassdeffounderror indicating libraries not being found.

i tried remaking jar file , included lib directory , contents, still no dice...

how can execute jar file command line , specify classpath use?

when specify -jar -cp parameter ignored.

from the documentation:

when use option, jar file source of user classes, , other user class path settings ignored.

you cannot "include" needed jar files jar file (you need extract contents , put .class files jar file)

you have 2 options:

  1. include jar files lib directory manifest (you can use relative paths there)
  2. specify (including jar) on commandline using -cp:
    java -cp myjar.jar:lib/* com.somepackage.subpackage.main
