I was trying to keep my Keycloak instances versions in sync with RH SSO but couldn't find the specified releases on Keycloak Github repository.
So, inspired by @hasalex work on get JBoss EAP builds from source code, I tried the same approach to RH SSO.
As RH SSO runs over JBoss EAP, you have to build it first.
You have to build the artifact wildfly-feature-pack from JBoss EAP sources in the required version for your SSO build succeed. You can verify the correct version in the Red Hat Single Sign-On Component Details page. This can be achieved by using eap-build scripts mentioned above.
First, you have to run the full EAP build. After that, you can build wildfly-feature-pack found in work/jboss-eap-X.X-src/feature-pack using mvn clean install -s ../../../src/settings.xml -DskipTests -Drelease=true -DlegacyRelease=true -Denforcer.skip.
With the dependencies set, you can get the RH SSO build script with git or wget.
If you want to run the script :
git clone git://github.com/luishgo/rh-sso-build.git
cd rh-sso-build
./build-sso.sh
By default, it builds the latest RH-SSO 7 update. You can build other versions by passing the number to the build :
./build-sso.sh 7.4.5
If you don't want to use git, download the archive, unzip it and run the main script :
wget https://github.com/luishgo/rh-sso-build/archive/master.zip
unzip master.zip
cd rh-sso-master
./build-sso.sh
The build-sso.sh uses a custom maven settings.xml which seems to be ignored by galleon-maven-plugin. Keep that in mind if you have a custom setting.xml on your own, particularly a localRepository setting.
The build-sso.sh script supports 7.4.5->7.4.9.
The script is in bash. It should run on almost all bash-compatible systems. You have to install wget, unzip, patch, java (JDK), grep, curl and xmlstarlet first.
