sorry for not replying in time. the logic here is that firstly unrecognized
- -options show warning message and usage informationï¼secondly the - options
end the while loop and treat the current one and following options as maven
parameters which will be handled later by mavenï¼and finally all other
unrecognized options fail the process immediately.
