The tool can execute files with suffix .groovy as groovy scripts.

It does not make any difference whether you invoke a groovy script from within a xml configuration or directly by placing it in the scripts directory (prefix up-) for automatic invocation, except that you cannot provide additional parameters when invoking the script automatically.

Important hints: Groovy scripts are compiled to classes as well. The naming of the scripts might be important:

• do not prefix them with "up-", because script name must no contain "-".

Solution: configure "Scripts-Prefix" = "up"

• use "" in the version format instead of ".", because "." indicates a package path in the script name, which might lead to surprising side effects

Solution: name your scripts in format "up_1_0_0_myscript.groovy" instead "up-1.0.0_myscript.groovy"
