Hi, Timothy,
Thanks for your reply. Seems jarjar is a solution for me. I have a basic
question to follow:
I don't quite understand what is tag <keep> for ?
My understand is
1.
use <include> to grab the maven dependencies I want to re-package,
2.
then use <pattern> and <result> in <rule> to define what class to
re-package and what's the new name for re-packaged binary.
3.
And use <keep> to indicate which class in the project will only use this
re-packaged dependencies, in my case, it is JDBC class. Am I right ?
below pom doesn't work for me, and JDBC class and other class still share
the same thrift 0.9. Thrift 0.7 is omitted.
Thanks a lot for help,
Johnny
