| conf | a 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 | 
    | inline | true to use inline mode, false to resolve an ivy file (since 1.4) | No. defaults false | 
    | organisation | the 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 | 
    | module | the 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 | 
    | revision | the revision constraint of the module to retrieve. Used only in inline mode. since 1.4 | No. Defaults to latest.integration | 
    | branch | the name of the branch to resolve in inline mode (since 2.1) | Defaults to no branch in inline mode, nothing in standard mode. | 
    | changing | indicates 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. | 
    | transitive | true to resolve dependencies transitively, false otherwise since 1.4 | No. Defaults to true | 
    | resolveMode | the [[ant:resolve resolve mode]] to use when an automatic resolve is triggered (since 2.1) | No. defaults to using the resolve mode set in the [[settings settings]] | 
    | keep | true 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 | 
    | haltonfailure | true to halt the build on ivy failure, false to continue | No. Defaults to true | 
    | validate | true to force ivy files validation against ivy.xsd, false to force no validation | No. Defaults to default ivy value (as configured in configuration file) | 
    | refresh | true to force Ivy to resolve dynamic revision in this resolve process, false to use cached resolved revision since 2.1 | No. defaults to false | 
    | file | the file to resolve if a resolve is necessary since 2.0 | No. Defaults to the previous resolved Ivy file or to ${ivy.dep.file} | 
	| settingsRef | A reference to the ivy settings that must be used by this task (since 2.0) | No, 'ivy.instance' is taken by default. | 
	| resolveId | The 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]'. | 
    | log | the log setting to use during the resolve process. (since 2.0) Available options are:
 defaultthe default log settings, where all usual messages are output to the consoledownload-onlydisable all usual messages but download ones. A resolve with everything in cache won't output any message.quietdisable all usual messages, making the whole resolve process quiet unless errors occur
 | No, defaults to 'default'. |
