Next : 3. Project Relationships 3. Project Dependencies Maven can manage both internal and external dependencies. An internal dependency is illustrated by a web application project depending on another project that contains service classes, model objects, or persistence logic. Project Dependencies shows some examples of project dependencies.

Alternatively if you are using the Maven deploy plugin, which is the default behavior, you need to add a full distributionManagement section. In addition you can configure the gpg command in case it is different from gpg. This is a common scenario on some operating systems. To configure it simply add the plugin to your Maven pom.
Deprecated oss-parent In the past all the plugin configuration and other setup was managed by a Maven parent POM with the latest coordinates of org. Maintenance of the project has stopped and it no longer works with latest tooling such as Maven versions or Java versions. If desired, please manage your own organization-level POM in a similar manner.
Using a Profile Since the generation of the javadoc and source jars as well as signing components with GPG is a fairly time consuming process, these executions are typically isolated from the normal build configuration and moved into a profile.
This profile is then in turn used when a deployment is performed by activating the profile. You do not need to fulfill the requirements when performing snapshot deployments and can simply run mvn clean deploy on your project. This ensures that you only depend on other released components. Ideally they are all available in the Central Repository. This ensures that your users can retrieve your components as well as your transitive dependencies from the Central Repository. The change of the versions for your project, and the parent references in a multi module setup, can be performed manually or with the help of the Maven versions plugin.
If you want to ensure that a specific version in the Central Repository corresponds to a specific revisions in your SCM system, which is a good practice, you can either perform the commits manually in a flow similar to Develop, develop, develop.
