The Maven Configuration below /configureTools/ is currently not exported to the YAML config. That is handy as it allows to bind specific configuration files which can already be configured via unclassified.globalConfigFiles (as outlined in https://github.com/jenkinsci/configuration-as-code-plugin/tree/master/demos/config-file-provider).

This has been initially reported at https://github.com/jenkinsci/configuration-as-code-plugin/issues/1370.
