Hi !
Looking at the pom.xml file, the mysql-connector-java version should be 5.1.40 the in the downloadable build (https://github.com/ConfigHubPub/ConfigHubPlatform/releases/tag/v1.9.7) the version is 5.1.37.
Maybe there are other dependencies not up to date, I did not checked.
Could you tell where is the folder template used to generate a downloadable zip which is ready to install ?
Thank you very much !
