# dependencies

Tag: dependencies Parent: ivy-module

Container for dependency elements, used to describe the dependencies of this module. If this container is not present, it is assumed that the module has no dependencies at all.

This container provides two similar behaviors described below. (See configurations doc page for more details about these behaviors).

(since 1.1) `defaultconf` defines the `conf` attribute to use when no conf is defined for a dependency in this Ivy file. It is only used when no conf mapping is defined, and has no influence in other cases.

(since 1.3) `defaultconfmapping` influences the way that a conf mapping with no mapped conf is interpreted.

(since 2.2) Attributes `defaultconf` and `defaultconfmapping` can be used together. In earlier versions, if both `defaultconf` and `defaultconfmapping` are defined, it’s the `defaultconfmapping` that is used.

(since 1.4) You can activate a `confmappingoverride` mode for all configurations, in which case the extending configurations will override the mappings of the configurations they extend from.

(since 2.5) Attributes inherited via `extends` are added to `dependencies` only on delivery and override attributes inherited from `configurations`.

## Attributes

Attribute | Description | Required
--- | --- | ---
defaultconf | the default configuration to use when none is specified in a dependency. (since 1.1) | No, defaults to `*->*`
defaultconfmapping | the default configuration mapping to use in this Ivy file. (since 1.3) | No, defaults to no default conf mapping
confmappingoverride | `true` to activate configuration mapping override, `false` otherwise. (since 1.4) | No, defaults to `false`

## Child elements

Note: as specified by the ivy.xsd, the children elements are ordered; first must come the `dependency` elements, then the `exclude` elements, then the `override` elements, and then the `conflict` elements.

Element | Description | Cardinality
--- | --- | ---
dependency | declares a dependency for this module | 0..n
exclude | excludes artifacts, modules or whole organizations from the set of dependencies of this module (since 2.0) | 0..n
override | specifies an override mediation rule, overriding the revision and/or branch requested for a transitive dependency (since 2.0) | 0..n
conflict | specifies a conflict manager for one or several dependencies (since 2.0) | 0..n
