- Add a property to one of the Install job properties files.
- Add a new line in the idp.properties file that sets the Spring runtime property to its Install time value (foo.bar=${foo.bar}).
- Reference the run time property in the configuration file using % instead of $ (logdirectory="%{foo.bar}")
Of course, you could decide not to do things the way Shib does them, you could move the configuration file to the updateArtifactSubstituteVariables directory tree and then just reference the property as ${foo.bar}. Then the variable will be replaced by the value at install time and there will be no runtime substitution. It should work the same, but it is not the Shib way to do it.
