# makepom since 2.0 The makepom task allows to convert an ivy file to a pom file. An example of use is to publish an Ivy managed module to a maven 2 repository. Note that all Ivy features are not supported by maven poms, so the converted pom may not resolve to the exact same dependencies as the original ivy file. since 2.2 It is possible to specify a template file defining the structure of the generated POM. The following processing is done on this template: properties like ${property.name} are replaced if they are defined in Ant or by the ivy:makepom task (see below for the standard properties) lines containg the string SKIP_LINE are skipped. the defined dependencies will be added to the first element encountered in the pom template. If the template doesn't contain a element, it is generated a the end of the pom. The ivy:makepom task defines following properties that can be used in the template. ivy.pom.groupId: defaults to the organisation as defined in the ivy.xml file ivy.pom.artifactId: defaults to the value of the 'atifactName' attribute of this task, or the name of the module as defined in the ivy.xml file ivy.pom.packaging: defaults to the value of the 'artifactPackaging' attribute of this task, or the extenstion of the artifact ivy.pom.version: defaults to the revision as defined in the ivy.xml file ivy.pom.name: defaults to 'SKIP_LINE' ivy.pom.description: defaults to the value of the 'description' attribute of this task, or 'SKIP_LINE' when not specified ivy.pom.url: defaults to the homepage as defined in the ivy.xml file ivy.pom.license: the content of the specified headerFile, or 'SKIP_LINE' if not specified ivy.pom.header: some Ivy information, or 'SKIP_LINE' if the 'printIvyInfo' attribute is set to false. Note that each property can be given a value manually in the Ant build file. In that case, Ivy will use the value specified in the build file instead of the default value. The default template that ships with Ivy looks like this:
    ${ivy.pom.license}
    ${ivy.pom.header}

# Attributes
Attribute | Description | Required
--- | --- | ---
ivyfile | the source ivy file to convert | Yes
pomfile | the destination pom file to write | Yes
templatefile | the template file to use when generating the pom (since 2.2) | No, defaults to the internal template file.
artifactName | The name of the artifact which is represented by the generated pom file. (since 2.2) | No, defaults to the module name in the source ivy file.
artifactPackaging | The packaging of the artifact which is represented by the generated pom file. (since 2.2) | No, the artifact ext is taken by default. Defaults to 'pom' if no such artifact is defined.
conf | a comma separated list of the configurations to include in the generated pom. Wildcards are supported here. (since 2.2) | No, defaults to all configurations.
settingsRef | A reference to the ivy settings that must be used by this task | No, 'ivy.instance' is taken by default.
printIvyInfo | Add some information about Ivy to the generated POM. (since 2.2) | No, defaults to 'true'.
headerFile | the header of the generated pom file | No
description | The description that will be added to the generated pom. (since 2.2) | No, defaults to no description.
# Child elements
Element | Description | Cardinality
--- | --- | ---
mapping | describes the mapping from an Ivy module configuration to a Maven POM scope. These elements takes two attributes: conf the configuration to map scope the scope to which it should be mapped | 0..n
dependency | describes extra dependencies that should be added to the generated Maven POM file. These elements takes the following attributes: group the groupId. Default organisation as defined in info artifact the name of the artifact version the version. Default revision as defined in info scope the scope optional is the artifact optional. Default false | 0..n
# Examples
    <ivy:makepom ivyfile="${basedir}/path/to/ivy.xml" pomfile="${basedir}/path/to/module.pom" conf="default,runtime">
       <mapping conf="default" scope="compile"/>
       <mapping conf="runtime" scope="runtime"/>
       <dependency group="com.acme" artifact="acme-logging" version="1.0" optional="true"/>
    </ivy:makepom>
Converts ${basedir}/path/to/ivy.xml to a pom and writes the result to ${basedir}/path/to/module.pom. The configuration 'default' in the parsed ivy file will be mapped to the scope 'compile', the configuration 'runtime' will be mapped to 'runtime', and other configurations will be excluded. The com.acme.acme-logging artifact with version 1.0 will be added as an optional dependency.
