post resolve tasks

Several tasks in Ivy are considered as post resolve task and share a common behaviour and settings accordingly.

These tasks are: All these tasks will trigger automatically a resolve if:
  • none has already been called in the current build with the attribute keep set to true (see below)
  • organisation and module are not set
Since Ivy 1.4, there are two ways to run a resolve: with an ivy file, or with the inline mode.
When you call resolve with an ivy file, the default for it is to keep the resolved data for use by the subsequent post resolve tasks. When you run an inline resolve, the default is not to keep the data. You can override this behaviour by setting the keep attribute as you like.

If you want to to reuse the resolved data obtained through a call to resolve in another build (i.e. not the current one), then you have to set the organisation and module attributes. This work only if the cache was not cleaned since your last resolve call. This does not work with inline calls, which must be performed in the same build.

The attributes listed are then mostly used only if a resolve is triggered automatically.


confa comma separated list of the configurations to retrieve or '*'.
Since 2.0 you can also use '*(public)' or '*(private)'. Note that '*' is interpreted as '*(public)' when inline is true.
No. Defaults to the configurations resolved by the last resolve call, or '*' if no resolve was explicitly called
inlinetrue to use inline mode, false to resolve an ivy file (since 1.4)No. defaults false
organisationthe organisation of the module to retrieve. This usually doesn't need to be set since it defaults to the last resolved one, except for inline mode where it is required.Yes in inline mode, otherwise no, it then defaults to last resolved module name
modulethe name of the module to retrieve. This usually doesn't need to be set since it defaults to the last resolved one, except for inline mode where it is required.Yes in inline mode, otherwise no, it then defaults to last resolved module name
revisionthe revision constraint of the module to retrieve. Used only in inline mode. since 1.4No. Defaults to latest.integration
branchthe name of the branch to resolve in inline mode (since 2.1)Defaults to no branch in inline mode, nothing in standard mode.
changingindicates that the module may change when resolving in inline mode. See cache and change management for details. Ignored when resolving in standard mode. (since 2.2.0)No. Defaults to false.
transitivetrue to resolve dependencies transitively, false otherwise since 1.4No. Defaults to true
resolveModethe resolve mode to use when an automatic resolve is triggered (since 2.1)No. defaults to using the resolve mode set in the settings
keeptrue to keep the results of the automatic resolve in memory, false to discard them. When this is false, the standard ivy properties won't be set and other postresolve-tasks (like retrieve and cachepath) won't be able to resuse the results of this resolve!No. defaults to false for an inline resolve and to true in any other case
haltonfailuretrue to halt the build on ivy failure, false to continueNo. Defaults to true
validatetrue to force ivy files validation against ivy.xsd, false to force no validationNo. Defaults to default ivy value (as configured in configuration file)
refreshtrue to force Ivy to resolve dynamic revision in this resolve process, false to use cached resolved revision since 2.1No. defaults to false
filethe file to resolve if a resolve is necessary since 2.0No. Defaults to the previous resolved Ivy file or to ${ivy.dep.file}
settingsRefA reference to the ivy settings that must be used by this task (since 2.0)No, 'ivy.instance' is taken by default.
resolveIdThe id which was used for a previous resolve, or the resolveId if a new resolve is performed (since 2.0)No, defaults to '[org]-[module]'.
logthe log setting to use during the resolve process. (since 2.0)
Available options are:
  • default
  • the default log settings, where all usual messages are output to the console
  • download-only
  • disable all usual messages but download ones. A resolve with everything in cache won't output any message.
  • quiet
  • disable all usual messages, making the whole resolve process quiet unless errors occur
No, defaults to 'default'.

Child elements

(Since 2.3)

These child elements are defining an inlined ivy.xml's dependencies elements. Thus these child elements cannot be used together with the inline or file attributes.
There is one important difference with the ivy.xml's dependencies: there is no master configuration to handle here. There is actually only one, the one on which the resolve will run. So every attribute in dependency, exclude, override or conflict which is about a master configuration is not supported. And every attribute about a mapping of a master configuration on a dependency configuration is now expecting only the dependency configuration.
dependencydeclares a dependency to resolve 0..n
excludeexcludes artifacts, modules or whole organizations from the set of dependencies to resolve 0..n
overridespecify an override mediation rule, overriding the revision and/or branch requested for a transitive dependency since 2.0 0..n
conflictspecify a a conflict manager for one or several dependencies since 2.0


<ivy:cachepath organisation="emma" module="emma" revision="2.0.4217" inline="true" conf="ant" pathid="emma.classpath"/>
<taskdef resource="" classpathref="emma.classpath" />
Resolves the emma module in version 2.0.4217, constructs an ant path with the corresponding artifacts, and then define the emma tasks using this path.
