we're using maven , nexus distribute components (maven projects) inside our infrastructure. sake of argument, let's have 2 teams: team foo , team bar; , component bar depends on component foo. team bar wants write contract tests checking if component foo behaves expected. tests run every night against latest stable development version of project foo (git master after ci). team bar write maven project bar/pom.xml depends on latest version of foo ? how can go doing that? we're playing idea of solving through version naming. name under development version master-snapshot (or something) , instead of version label going 0.1-snapshot -> 0.1 -> 0.2-snapshot -> 0.2 , go master-snapshot , master-snapshot -> 0.1 -> master-snapshot -> 0.2 . contract testing project bar declare dependency foo com.acme:foo:master-snapshot . but seems clunky (breaks common maven practice , stuff)... there more standard practice kind of thing? should use maven versions p
