Choose Grails version and configure GRAILS_HOME automatically
We are using Grails actively to develop web applications. So we ended up with different applications using different versions of framework.
GRAILS_HOME variable to point to different Grails release each time I switched to other application was really unpleasant hassle. So I thought about how to resolve this problem. Grails stores application version in
application.properties file, I came out to the following Bash script:
#!/bin/bash # Get required Grails version GRAILS_VERSION=`sed -n 's/app.grails.version=\(.*\)$/\1/p' < application.properties` # Set Grails home using configured prefix and determined version export GRAILS_HOME=$GRAILS_PREFIX$GRAILS_VERSION # Run original Grails script $GRAILS_HOME/bin/grails $@
It just parses the version from the
application.properties file and appends it to
GRAILS_PREFIX environment variable. The resulting value is exported into
To use the aforementioned script you need to set
GRAILS_PREFIX variable to a value appropriate for your system. And of course your Grails distributions should be installed side-by-side in one common folder.
For example I have it set to
/home/vg/tools/grails- on my Linux box.
You can grab/fork script easily as a Gist on GitHub.
UPD: The script was updated to take some corner cases into account. See updated version of the script.
UPD 2: There is also version for Windows.
