The download-java-all-os.sh is a script whose functioning is devised by Kathy Don to grab binaries for all release OS-es of a new JDK version from Zulu, then svn commit them to TRAC's cli-extensions/selfcontained-jdk/downloads

It's all to be done from a single linux machine, as only our assigned linux boxes have currently been given the privilege to svn commit large files.

***************************************************************
 USAGE: To commit the binaries of a new JDK version for all OS
***************************************************************
1. Sit at a UNIX machine that has permissions to SVN commit large files (>=100Mb) such as JDK tarballs to greenstone TRAC.

2. Run the following commands:

svn co --depth files https://svn.greenstone.org/main/trunk/cli-extensions
cd  cli-extensions
./download-java-all-os.sh <full-version>
   e.g. ./download-java-all-os.sh 11.88.17-ca-jdk11.0.31

3. Edit the following 2 files (maybe from a release-machine's gs-release-builder/ext-cli folder):
- https://svn.greenstone.org/main/trunk/ext-cli/get-selfcontained-jdk.sh
- https://svn.greenstone.org/main/trunk/ext-cli/get-selfcontained-jdk.bat
to update their value for their JDK11 variable to the new JDK <full-version>
you provided to the download-java-all-os.sh script.

NOTE: If moving up from JDK11 to JDKN, then
- create a new variable JDKN=<full-version>
- update GS_VER=N,
- update GS_JDK=%JDKN% (GS_JDK=$JDKN in get-selfcontained-jdk.sh)
- The usage() display may need updating
- But the minimum version of JDK expected by Greenstone must also be updated in gs3-setup.sh|bat for GS3, and gs2build/setup.bas|bat for GS2.
- Not sure if search4j is affected, but if so, it needs updating, and gs-release-builder/release-kits will need an SVN update run on it

If moving up EXP_VER to Nfx, then in get-selfcontained-jdk:
- create a new variable JDKN_FX_64=<full-fx-version>
- update EXP_VER=Nfx
- update EXP_JDK_FX=$JDKN_FX_64
- Maybe the usage display needs updating
- Not sure if search4j is affected, but if so, see above.

Update this README if any other affected files are identified that need modifying when changing to a new JDK major version number.

4. svn commit both ext-cli/get-selfcontained-jdk.sh and ext-cli/get-selfcontained-jdk.bat

5. On each release-machine, cd into gs-release-builder/ext-cli and svn update.
