# exclude

Tag: exclude Parent: dependency
This feature gives you more control on a dependency for which you do not control its ivy file.
It enables to restrict the artifacts required, by excluding artifacts being published by the dependency or any of its transitive dependencies,
even if configuration does not a good separation of published artifacts
The same principle concerning configuration as for include applies to this exclude feature (see the include feature).
Note that exclusion is always done AFTER inclusion has been done.
since 1.3 This exclude feature can also be used not only to exclude artifacts but also to exclude whole modules. Indeed when you exclude artifacts, it doesn't avoid ivy to search for the module itself, and to resolve the dependencies of the module. But you can also exclude the whole module, which means that the module will not be downloaded at all, and so its own dependencies will not be resolved. For sure, this is usually done to exclude not a direct dependency but an indirect one. To exclude a whole module, you just have to not specify any artifact name, type and ext in your exclude rule. For instance:

    <dependency name="A" rev="1.0">
      <exclude module="B"/>
    </dependency>

since 2.0 A module wide exclude can also be used to exclude dependencies for the whole module (and not only in the context of one dependency as it is the case here).

module | the name of the dependency module or the artifact to exclude, or a regexp matching this module name since 1.3 | No, defaults to *
name | the name of an artifact of the dependency module to add to the exclude list, or an expression matching this name (see matcher attribute below) | No, defaults to *
type | the type of the artifact of the dependency module to add to the exclude list, or a regexp matching this name | No, defaults to *
ext | the extension of the artifact of the dependency module to add to the exclude list, or an expression matching this name (see matcher attribute below) | No, defaults to type
matcher | the matcher to use to match the modules to excludes since 1.3 | No, defaults to exactOrRegexp in pre 1.3 ivy files, and exact in 1.3 and superior
conf | comma separated list of the master configurations in which this artifact should be excluded. '*' wildcard can be used to designate all configurations of this module | No, defaults to '*', unless nested conf are specified
