Sometimes, the groupId that is obtained from groupIDFromJavaMetadata is not quite correct, in that it contains some version of the artifactId in the path. For example:
https://repo1.maven.org/maven2/com/jayway/jsonpath/json-path/2.4.0/
Syft doesn't find a license because the groupId is com.jayway.jsonpath.json-path instead of com.jayway.jsonpath. Also:
https://repo1.maven.org/maven2/com/google/api/api-common/2.2.0/
Syft doesn't find a license because the groupId is com.google.api.apicommon instead of com.google.api.
The PR falls back to stripping the last package name from the groupId to see if it can find a pom from Maven central. Licenses are found correctly for the two examples above.
