java - How does Maven manage duplicate artifactIds when they belong to a different group? -

-

i'm building different web projects maven , thinking how name artifacts. rest api layer, it's convenient share classes, want create exchange-api.jar files shared among different projects.

let's suppose i've got web application has it's own exchange-api module. groupid com.mycompany.app1 whole maven id artifact should com.mycompany.app1:exchange-api:1.0. let's suppose want access other app's api application. have include dependency com.mycompany.app2:exchange-api:1.0. artifactids same, groupid different. however, both should end exchange-api-1.0.jar in classpath.

how maven take care of this? should use unique artifactid each of them?

maven manages problem allowing customize file name mapping, can done both war , ear applications. think naming convention poor. suppose projects publicly downloadable , people not using maven download them manually , add them projects: think generic "exchange-api" clear enough? think no. names app1-exchange-api , app2-exchange-api. or app1-api , app2-api. there several examples of rule: spring, hibernate , on.
