Description
How to replicate: just generate new project [1] and provide any value for secretKey: you will end up with the following content in core/src/main/resources/security.properties:
adminUser=admin
adminPassword=5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8
adminPasswordAlgorithm=SHA1
secretKey=${secretKey}
which shows an unresolved ${secretKey}.
