Wanted: Working Example of SpringBoot2/hibernate5 with hbm2java (the "Reverse Engineering Feature")

[Siegfried Heintze]

There is a great example of Gradle/Hibernate/hbm2/SpringBoot Spring5 & Angular Video Tutorial with Free Accompanying Source code From PacktPub.com in chapter two except it does not work!

Doing "./gradlew hbm2java" after having configured mysql gave this error:

[ant:hibernatetool] Thu Nov 29 14:34:07 PST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

When I tried bumping the spring boot version from 2.0.0.RC1 to 2.1.0.RELEASE I got a slightly different error:

:hbm2java

Can someone show me a working example? Preferably with gradle using the hibernate plugin, but maven will do.

Thanks
