Hi,
Thank you Redhuan, Alejandro Guerra and Carlos Ruiz,
I've tried 2pack from
https://bitbucket.org/dcs_bitbucket/liberohr_ve, but i did not work with this message "File does not exist: /tmp/packin0/dcs_bitbucket-liberohr_ve-9e8e0c2d383e/dict/PackOut.xml"
The one that I download from redhuan/p2 works fine if I install it to iDempiere 2.1 installer (31 Oct 2014), it does not work only if I install it to the Daily (the latest is 24 Jul 2015), IMHO the problem is not from LiberoHR_plugins.jar but from the new iDempiere package (something change in development). I really appreciate for the advice. Thank you.
Best regards,
Hadi Handojo
