root/gli/trunk/findjava.sh @ 19740

Revision 19740, 6.1 KB (checked in by ak19, 11 years ago)

Modification to make it the same as the findjava.sh used by gs2-server.sh (at present that one's located in the GS2 installation folder, later we can have just one file that is then checked out from svn). Now findjava.sh won't check for the version of GS before testing the location for search4j.

  • Property svn:executable set to *

1# We will already be in the correct folder (GLI folder), which would
2# contain a compiled up search4j if this GLI is part of an installation.
3# If a search4j executable is not there, then it means this is an SVN checkout.
4# In such a case, it's up to the user checking things out to ensure JAVA_HOME
5# is set and moreover points to the correct version of the Java.
