[FIXED] Maven deploy -> error org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy fails, but no mention of plugin in pom?

Issue

I have a simple POM (see below). When I execute mvn deploy I get this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project piccolotest: Deployment failed: repository element was not specified in the POM inside distributionManagement element or in -DaltDeploymentRepository=id::layout::url parameter -> [Help 1]

There is no direct mention of the maven plugin in the pox, so I guess it's grabbed from somewhere else. What am I missing?

Pom file...

Solution

per packaging-type, in your case jar, is a predefined set of plugins bound to several phases. Since these can change for every new version of Maven it is best practice to lock the versions for these plugins. If you really want to know the location, it's https://git-wip-us.apache.org/repos/asf?p=maven.git;a=blob;f=maven-core/src/main/resources/META-INF/plexus/default-bindings.xml;h=09ecba441e61d4a997b01af0171815c558548537;hb=HEAD
