Summary
This PR fixes an uncaught exception that can be triggered by XML files with restricted content.
Description of changes
When searching for repositories for Maven projects, Macaron must parse the contents of the related POM files in the XML format. Use of the
defusedxmllibrary addresses the various security concerns this parsing involves, but the exceptions these cases can raise have not yet been accounted for.This PR makes a small adjustment to the
pomparsermodule, extending the catch clause to include thedefusedxmlsecurity related exceptions.A unit test has also been included with examples of valid and invalid XML files.
