root/main/trunk/greenstone3/gs3-setup.sh @ 30755

Revision 30755, 9.5 KB (checked in by davidb, 3 years ago)

Greenstone code was overriding custom Java_Home set on Mac. We want to control that Java_Home to 1.7 to match the JRE we're including so first preference for Java_Home HINT to search4j is any JAVA_HOME already set.

  • Property svn:executable set to *
  • Property svn:keywords set to Author Date Id Revision
