Load unsafe mapping for all dependencies with no license in their pom, we will load the missing file if it exists and also add all dependencies from licenseMap with no license known.

Parameters:

licenseMap - the license map of all dependencies.

missingFile - location of an optional missing fille (says where you fix missing license).

                                     ThirdPartyToolException

Loads unsafe mappings. Unsafe mappings are files that supply license metadata for artifacts that lack it in their POM models. It's called 'unsafe' because its safer to see actual metadata.

There are three sources of this data:

• the 'missing' file.
• additional property files attached to artifacts; these have classifier=third-party and are expected to contain the license information the base artifact's dependencies. These are controlled by a parameter,
• declared dependencies of type license.properties. These are in the same format, and provide global information.

Parameters:

licenseMap - license map to read

missingFile - location of an optional missing file

useRepositoryMissingFiles - flag to use or not third-party descriptors via the 'third-party' classifier from maven repositories

unsafeDependencies - all unsafe dependencies

projectDependencies - all project dependencies

Returns:

the loaded unsafe mapping

Throws:

org.apache.maven.project.ProjectBuildingException - if could not build some dependencies maven project

IOException - if could not load missing file

ThirdPartyToolException - if pb with third-party tool

mergeLicenses

void mergeLicenses(List<String> licenseMerges,
                   LicenseMap licenseMap)
            throws org.apache.maven.plugin.MojoFailureException

Merges licenses.

Parameters:

licenseMerges - list of license mergeables (each entry is a list of licenses separated by |, the first one is the license to use for all the others of the entry).

licenseMap - license map to merge

Throws:

org.apache.maven.plugin.MojoFailureException - if there is a bad license merge definition (says for example two license with same name)
