Sometimes it is required that multiple Grails projects, hosted on a different Grails version, run simultaneously. In this case, while fixing bugs, you are required to run the application after switching the Grails version each time.<\/p>\n

To handle this scenario, I wrote a utility shell script “runGrails” to use a particular version of Grails while running the scripts like run-app, test-app etc. The shell script contained these two lines:<\/p>\n

\n
export GRAILS_HOME=\/opt\/grails-$1\r\n$GRAILS_HOME\/bin\/grails $2<\/pre>\n<\/blockquote>\n
This script was put in a location coming under the “PATH”. It is assumed that the different versions of grails are under directories named grails-<version> <\/em>under \/opt\/.<\/em><\/p>\n
Now, to run different projects, we can call the script as:<\/p>\n
\n
runGrails 1.3.1 \"-Dserver.port=8082 run-app\"<\/pre>\n<\/blockquote>\n
which will run the project with grails version 1.3.1 at port 8082.<\/p>\n
PS: This works on *nix systems.<\/p>\n
Hope this helps.<\/p>\n","protected":false},"excerpt":{"rendered":"
