Hi @Yogesh_Gupta,
It looks like your system administrator is not using conda to install these. You should indicate to your sysadmin that you need a JRE where QIIME 2 is installed (openJDK should be fine) and to double check that these dependencies work as indicated by the conda recipe:
If it's possible, you might also ask for a user-controllable install of conda, then you could manage the installation (which is very straight-forward as long as it stays in conda). Then you should be able to avoid these situations.
