Maven
-----
Resolvers for Maven2 repositories are added as follows:
.. code-block:: scala
resolvers +=
"Sonatype OSS Snapshots" at "https://oss.sonatype.org/content/repositories/snapshots"
This is the most common kind of user-defined resolvers. The rest of this
page describes how to define other types of repositories.
Predefined
----------
A few predefined repositories are available and are listed below
- `DefaultMavenRepository` This is the main Maven repository at
http://repo1.maven.org/maven2/ and is included by default
- `JavaNet1Repository` This is the Maven 1 repository at
http://download.java.net/maven/1/
For example, to use the `java.net` repository, use the following
setting in your build definition:
::
resolvers += JavaNet1Repository
Predefined repositories will go under Resolver going forward so they are
in one place:
::
Resolver.sonatypeRepo("releases") // Or "snapshots"
Custom
------
sbt provides an interface to the repository types available in Ivy:
file, URL, SSH, and SFTP. A key feature of repositories in Ivy is using
`patterns <http://ant.apache.org/ivy/history/latest-milestone/concept.html#patterns>`_
to configure repositories.
Construct a repository definition using the factory in `sbt.Resolver`
for the desired type. This factory creates a `Repository` object that
can be further configured. The following table contains links to the Ivy
documentation for the repository type and the API documentation for the
factory and repository class. The SSH and SFTP repositories are
configured identically except for the name of the factory. Use
`Resolver.ssh` for SSH and `Resolver.sftp` for SFTP.

Basic Examples
~~~~~~~~~~~~~~
These are basic examples that use the default Maven-style repository
layout.
Filesystem
^^^^^^^^^^
Define a filesystem repository in the `test` directory of the current
working directory and declare that publishing to this repository must be
atomic.
::
resolvers += Resolver.file("my-test-repo", file("test")) transactional()
URL
^^^
Define a URL repository at `"http://example.org/repo-releases/"`.
::
resolvers += Resolver.url("my-test-repo", url("http://example.org/repo-releases/"))
To specify an Ivy repository, use:
::
resolvers += Resolver.url("my-test-repo", url)(Resolver.ivyStylePatterns)
or customize the layout pattern described in the Custom Layout section
below.
SFTP and SSH Repositories
^^^^^^^^^^^^^^^^^^^^^^^^^
The following defines a repository that is served by SFTP from host
`"example.org"`:
::
resolvers += Resolver.sftp("my-sftp-repo", "example.org")
To explicitly specify the port:
::
resolvers += Resolver.sftp("my-sftp-repo", "example.org", 22)
To specify a base path:
::
resolvers += Resolver.sftp("my-sftp-repo", "example.org", "maven2/repo-releases/")
Authentication for the repositories returned by `sftp` and `ssh` can
be configured by the `as` methods.
To use password authentication:
::
resolvers += Resolver.ssh("my-ssh-repo", "example.org") as("user", "password")
or to be prompted for the password:
::
resolvers += Resolver.ssh("my-ssh-repo", "example.org") as("user")
To use key authentication:
::
resolvers += {
val keyFile: File = ...
Resolver.ssh("my-ssh-repo", "example.org") as("user", keyFile, "keyFilePassword")
}
or if no keyfile password is required or if you want to be prompted for
it:
::
resolvers += Resolver.ssh("my-ssh-repo", "example.org") as("user", keyFile)
To specify the permissions used when publishing to the server:
::
resolvers += Resolver.ssh("my-ssh-repo", "example.org") withPermissions("0644")
This is a chmod-like mode specification.
Custom Layout
~~~~~~~~~~~~~
These examples specify custom repository layouts using patterns. The
factory methods accept an `Patterns` instance that defines the
patterns to use. The patterns are first resolved against the base file
or URL. The default patterns give the default Maven-style layout.
Provide a different Patterns object to use a different layout. For
example:
::
resolvers += Resolver.url("my-test-repo", url)( Patterns("[organisation]/[module]/[revision]/[artifact].[ext]") )
You can specify multiple patterns or patterns for the metadata and
artifacts separately. You can also specify whether the repository should
be Maven compatible (as defined by Ivy). See the `patterns
API <../../api/sbt/Patterns$.html>`_ for
the methods to use.
For filesystem and URL repositories, you can specify absolute patterns
by omitting the base URL, passing an empty `Patterns` instance, and
using `ivys` and `artifacts`:
::
resolvers += Resolver.url("my-test-repo") artifacts
"http://example.org/[organisation]/[module]/[revision]/[artifact].[ext]"
