If it is not a Bootique project, the property should work. A few non-Bootique projects that I still have (that are on Cayenne 4.0) are started using -Dcayenne.* properties from the docs.
If it is a Bootique project, you will need to use the Bootique approach to configure credentials for anything [1], Cayenne included. E.g. for a sample config [2], you'd be setting a value for the property "-Dbq.jdbc.mysql.password". Another way (preferred to -D IMO) is to define a shell variable pointing to the same property, and then exporting the var: in MyModule.java: BQCoreModule.extend(binder) .declareVar("jdbc.mysql.username", "DB_USER"); .declareVar("jdbc.mysql.password", "DB_PASSWORD"); in startup script: export DB_PASSWORD=root export DB_PASSWORD=secret java -jar my.jar # no password in the Java process sig Andrus [1] http://bootique.io/docs/0/bootique-docs/index.html#chapter-7-configuration-and-configurable-factories [2] https://github.com/bootique-examples/bootique-cayenne-demo/blob/master/config.yml > On Jan 17, 2018, at 12:22 AM, Pascal Robert <prob...@druide.com> wrote: > > Do -Dcayenne.jdbc.username really work?
