What data to expect in license-maven-plugin third party license FreeMarker template?

Question

I'm using the Mojo License Maven plugin to generate a list of third party licenses. According to the documentation I could use a custom FreeMarker template to format the file using the fileTemplate parameter, but there is no documentation on the data that will be passed to the FreeMarker template. There is a link on the examples page to existsing templates, but that link is broken.

Answer 1

After some searching I found the template on GitHub:

...

<#-- To render the third-party file.
 Available context :
 - dependencyMap a collection of Map.Entry with
   key are dependencies (as a MavenProject) (from the maven project)
   values are licenses of each dependency (array of string)
 - licenseMap a collection of Map.Entry with
   key are licenses of each dependency (array of string)
   values are all dependencies using this license
-->
<#function licenseFormat licenses>
    <#assign result = ""/>
    <#list licenses as license>
        <#assign result = result + " (" +license + ")"/>
    </#list>
    <#return result>
</#function>
<#function artifactFormat p>
    <#if p.name?index_of('Unnamed') &gt; -1>
        <#return p.artifactId + " (" + p.groupId + ":" + p.artifactId + ":" + p.version + " - " + (p.url!"no url defined") + ")">
    <#else>
        <#return p.name + " (" + p.groupId + ":" + p.artifactId + ":" + p.version + " - " + (p.url!"no url defined") + ")">
    </#if>
</#function>

<#if dependencyMap?size == 0>
The project has no dependencies.
<#else>
Lists of ${dependencyMap?size} third-party dependencies.
    <#list dependencyMap as e>
        <#assign project = e.getKey()/>
        <#assign licenses = e.getValue()/>
    ${licenseFormat(licenses)} ${artifactFormat(project)}
    </#list>
</#if>

It uses this LicenseMap
