Configuration Files of Apache Archiva
:STUB: This is a documentation stub.
While Archiva is primarily configured via the graphical administration interface, it stores all configuration in XML configuration
files that can be hand edited and used for backup and migration.
The following files compose the configuration for Archiva:
* <<<archiva.xml>>> - this is the primary Archiva configuration file
* <<<security.properties>>> - this configures the security as described in the {{{security.html} security configuration documentation}}
* <<<plexus.xml>>> - only applies when running the standalone Archiva instance, as described in the {{{standalone.html} installing Archiva standalone documentation}}
This section will focus on the <<<archiva.xml>>> file.
* The Archiva configuration file
The Archiva configuration file is stored in one of two locations:
* The application server configuration directory (see {{{standalone.html} installing Archiva standalone}} for more information)
* The user home directory (<<<~/.m2/archiva.xml>>>).
[]
When modified in the GUI, the file is written back to the location it was initially read from, with the home directory taking priority if both exist. When using a
standalone installation, it is highly recommended that a configuration file is only maintained in one of the locations.
The following shows a basic configuration file:

Apache Archiva Databases
:STUB: This is a documentation stub.
Archiva uses an external database for two purposes:
~~TODO: give general information on configuration for an external database
~~TODO: use mysql or external derby as an example
* Storing artifact information
* As a default user store for security
[]
Generally, it is unnecessary to configure anything - the built in embedded database is suitable for the artifact management, and if
an external authentication mechanism is not needed, the user database.
However, it is possible to configure an external database as needed.
* Configuring an external database
Archiva uses JNDI data sources to locate the databases to use:
* <<<jdbc/archiva>>> - the repository database
* <<<jdbc/users>>> - the user store
Configuring an external database for either or both of these sources depends is configured in <<<plexus.xml>>> if you are using the
{{{standalone.html} standalone installation}}, or in the application server configuration if you are using the {{{webapp.html} web application
installation}}.
* Backing up the database
While it is a good idea to back up both databases, it is not strictly necessary to back up the repository database on a regular basis. Should any
data loss be suffered, this database can be regenerated by deleting it's contents and re-scanning the repositories.
If you are using the default user security mechanism, it is important to back up the users database on a regular basis to ensure that the user
passwords and information are not lost in the event of corruption. With the default embedded storage this is simply a matter of making a copy of
the database directory on the filesystem. If you have configured an external database as the source for user information, please refer to your
database documentation for backup instructions.

Understanding Network Proxy Configuration of Apache Archiva
:STUB: This is a documentation stub.
Archiva uses the terminology "proxy" for two different concepts:
* The remote repository proxying cache, as configured through {{{proxy-connectors.html} proxy connectors}} between repositories
* Network proxies, which are traditional protocol based proxies (primarily for HTTP access to remote repositories over a firewall)
[]
Network proxies are configured using standard HTTP proxy settings as provided by your network administrator.
Once configured, the network proxy can be attached to operations that access remote resources. At present, this is configured on the
remote repository proxy connectors that need to access the remote repository over the HTTP protocol.

Understanding Proxy Connector Configuration of Apache Archiva
:STUB: This is a documentation stub.
Archiva uses the terminology "proxy" for two different concepts:
* The remote repository proxying cache, as configured through proxy connectors between repositories
* {{{network-proxies.html} Network proxies}}, which are traditional protocol based proxies (primarily for HTTP access to remote repositories over a firewall)
[]
A proxy connector is used to link a managed repository (stored on the Archiva machine) to a remote repository (accessed via a URL). This will mean that when a request
is received by the managed repository, the connector is consulted to decide whether it should request the resource from the remote repository (and potentially cache
the result locally for future requests).
Each managed repository can proxy multiple remote repositories to allow grouping of repositories through a single interface inside the Archiva instance. For instance,
it is common to proxy all remote releases through a single repository for Archiva, as well as a single snapshot repository for all remote snapshot repositories.
A basic proxy connector configuration simply links the remote repository to the managed repository (with an optional network proxy for access through a firewall).
However, the behaviour of different types of artifacts and paths can be specifically managed by the proxy connectors to make access to remote repositories more flexibly controlled.
* Configuring policies
When an artifact is requested from the managed repository and a proxy connector is configured, the policies for the connector are first consulted to decide whether
to retrieve and cache the remote artifact or not. Which policies are applied depends on the type of artifact.
By default, Archiva comes with the following policies:
* <<<releases>>> - how to behave for released artifact metadata (those not carrying a <<<SNAPSHOT>>> version). This can be set to <<<always>>> (default), <<<hourly>>>, <<<daily>>>, <<<once>>> and <<<never>>>.
* <<<snapshots>>> - how to behave for snapshot artifact metadata (those carrying a <<<SNAPSHOT>>> version). This can be set to <<<always>>> (default), <<<hourly>>>, <<<daily>>>, <<<once>>> and <<<never>>>.
* <<<checksum>>> - how to handle incorrect checksums when downloading an artifact from the remote repository (ie, the checksum of the artifact does not match the corresponding detached checksum file).
The options are to fail the request for the remote artifact, fix the checksum on the fly (default), or simply ignore the incorrect checksum
* <<<cache-failures>>> - whether failures retrieving the remote artifact should be cached (to save network bandwidth for missing or bad artifacts), or uncached (default).
[]
* Configuring whitelists and blacklists
By default, all artifact requests to the managed repository are proxied to the remote repository via the proxy connector if the policies pass. However, it can be more efficient to
configure whitelists and blacklists for a given remote repository that match the expected artifacts to be retrieved.
If only a whitelist is configured, all requests not matching one of the whitelisted elements will be rejected. Conversely, if only a blacklist is configured, all requests not matching one of
the blacklisted elements will be accepted (while those matching will be rejected). If both a whitelist and blacklist are defined, a path must be listed in the whitelist and not in the blacklist
to be accepted - all other requests are rejected.
The path in the whitelist or blacklist is a repository path, and not an artifact path, and matches the request and format of the remote repository. The characters <<<*>>> and <<<**>>> are wildcards,
with <<<*>>> matching anything in the current path, while <<<**>>> matches anything in the current path and deeper in the directory hierarchy.
For instance, to only retrieve artifacts in the Apache group ID from a repository, but no artifacts from the Maven group ID, you would configure the following:
* White list: <<<org/apache/**>>>
* Black list: <<<org/apache/maven/**>>>
