It is undecided whether plugins really need a remote repository set of their own. dependencies 3.0.0+ This element describes all of the dependencies associated with a project. Each dependency is described by a dependency element, which is then described by additional elements (described below).

These dependencies are used to construct a classpath for your project during the build process.

Maven can automatically download these dependencies from a remote repository.

The filename that Maven downloads from the repository is artifactId-version.jar where artifactId corresponds to the artifactId element and version corresponds to the version element.

When Maven goes looking for a dependency in the remote repository, it uses the dependency element to construct the URL to download from. This URL is defined as:

${repo}/${groupId}/${type}s/${artifactId}-${version}.${type}

Where

repo: is the remote repository URL specified by ${maven.repo.remote}
groupId: is taken from the dependency element
type: is taken from the dependency element
artifactId: is taken from the dependency element
version: is taken from the dependency element

The source configuration management system URL that describes the repository and how to connect to the repository. This is used by Maven when building versions from specific ID.

The format of this element is as follows:

scm:<provider>:<provider-parameters>

For cvs, the format for pserver repositories should be:

scm:cvs:pserver:user@host:/cvs/root:module-name

For local networked repositories (eg. pserver to local machine)

scm:cvs:lserver:user@host:/cvs/root:module-name

For ssh access:

scm:cvs:ext:user@host:/cvs/root:module-name

Remember that CVS will expect an environment variable called CVS_RSH to be set, typically to ssh or your ssh client.

Some cvs clients support other protocols, such as ntserver and extssh. Here's an example using CVS NT and ntserver:

scm|cvs|ntserver|user@server|e:\cvs|Deployment

Note the use of the vertical bar as delimiter as the repository has a colon (:) in it.

For local file system repositories

scm:cvs:local:ignored:/cvs/root:module-name

For StarTeam access:

scm:starteam:username:password@host:port/project/view/folder

All of this information can be had from either the StarTeam Universal Client (Tools->Server Administration->Server Properties) or from the administrator.

Where pserver is the protocol used to access CVS, user@host is the user name to log in to the specified cvs host, /cvs/root is the cvs root directory, and module-name is the name of the cvs module to be worked on

As an example, the settings for an Apache project are usually:

scm:cvs:pserver:anoncvs@cvs.apache.org:/home/cvspublic:module-name

Currently CVS, Starteam and SubVersion are the only supported scm's. Others will be added as soon as possible
