* Upgrade japicmp-maven-plugin to 0.15.2
* Do not use deprecated for removal Long constructor
* Update Spring to 5.3.3
* Upgrade Lombok to 1.18.16 + add lombok-mapstruct-binding
Make sure that MappingReferences are taken into consideration when comparing whether 2 mapping methods are equal.
This makes sure that when using nested target mappings that have the same property mappings, but different mappings 2 distinct methods will be created
When having multiple source properties and only target is defined then the same rules should be applied as if there was no mapping:
* First we check for a matching property in any of the source type
* Second we check if the parameter name matches
Upgrades:
* Maven Enforcer Plugin to 3.0.0-M3
* Maven Surefire Plugin to 3.0.0-M5
* Maven Checkstyle Plugin to 3.1.1
* Maven Bundle Plugin to 5.1.1
* Jacoco Maven Plugin to 0.8.6
* Checkstyle to 8.36.1
* JUnit Jipiter to 5.7.0
* AssertJ to 3.17.2
* Guava to 29.0-jre
Fix AssertJ breaking changes
Use Java 8 or Apache Commons IO instead of Guava where possible
Update GitHub Actions to use JDK 14 and JDK 15-ea
New rules:
1. Constructor annotated with @Default (from any package) has highest precedence
2. If there is a single public constructor then it would be used to construct the object
3. If a parameterless constructor exists then it would be used to construct the object, and the other constructors will be ignored
Add a new EnumNamingStrategy SPI which can be used for customising the way enums are matched by name.
It is similar to the AccessorNamingStrategy such that it allows implementors to provide a custom way of defining a property.
Related to #796, #1220, #1789 and #1667
Add a new custom EnumTransformationStrategy SPI which can be used for providing custom way of name based mapping for enums.
Add 4 out of the box transformation strategies:
* prefix - add a prefix to the name based enum mapping
* stripPrefix - remove a prefix from the name based enum mapping
* suffix - add a suffix to the name based enum mapping
* stripSuffix - remove a suffix from the name based enum mapping
This can be achieved by using the new `EnumMapping`
e.g.
Add suffix `_TYPE` to all enums:
`@EnumMapping(nameTransformationStrategy = "suffix", configuration = "_TYPE")`
With this it would be possible to achieve what is needed in #796, #1220, #1789.
