To avoid any complications with functional changes between Hibernate 5
and Hibernate 6, this uses the hibernate-core-jakarta v5 module rather
than hibernate-core v6. This requires a specific dependency exclusion
in spring-webflow.gradle to make sure that hibernate-entitymanager
never causes both versions to be loaded. This can be simplified after
eventual adoption of Hibernate 6.
The Spring snapshot repository needs to be referenced in build.gradle
for this early stage work on SWF 3.
This commit removes the propdeps plugin.
"provided" configurations are replaced with "compileOnly", "testCompile"
configurations.
The "optional" configuration supported by propdeps is now replaced by a
local Gradle plugin defining a specific configuration for that.
As a result of that change, optional/provided dependencies are not
published with the POMs anymore.
This commit introduces the Spring dependency management Gradle
plugin. All dependency versions and BOMs are now managed in the
root project and declared in the modules directly.
