root/gli/trunk/findjava.sh @ 19403

Revision 19403, 6.2 KB (checked in by ak19, 11 years ago)

3 changes. 1. Moved gli.sh's logic for finding and setting GSDLHOME (and GSDL3SRCHOME and GSDL3HOME) into a separate bashfile: findgsdl.sh. 2. This script is now called by both gli.sh and client-gli.sh, since client-gli can from now on use the same logic to locate a local GS installation. The only difference is that if GSDLHOME is not found, then client-gli runs as before: no Download panel. 3. client-gli.sh will no longer be looking for a gs2build directory located inside a client-gli checkout, but instead search for a local GSDLHOME (including in the directory directly above, in case client-gli.sh is run from a normal GS checkout. IF a GSDLHOME is found (and perl too), then client-gli will enable the Download panel, and use the local GSDLHOME to do any downloading.
