Update GitHub Actions for tests to run on Java 11, 13, 16 and 17-ea.
Update Lombok so tests can run on 16+
Add jaxb-runtime dependency to the maven-jaxb2-plugin see https://github.com/highsource/maven-jaxb2-plugin/issues/148
Disable cdi integration test on Java 16+ until we find a solution for them
* 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
By default the constructor argument names are used to extract the target properties.
If a constructor is annotated with an annotation named `@ConstructorProperties` (from any package) then it would be used to extract the target properties.
If a mapping target has a parameterless empty constructor it would be used to instantiate the target.
When there are multiple constructors then an annotation named `@Default` (from any package) can be used to mark a constructor that should be used by default when instantiating the target.
Supports mapping into Java 14 Records and Kotlin data classes out of the box
Due to a bug in javac (JDK-8229535) for an annotation with Class values, instead of returning a TypeMirror with TypeKind#ERROR the compiler returns the string "<error>". Eclipse doesn't have this problem currently.
Disable one test in GenericsHierarchyTest for Eclipse on Java 8 due to a bug in the Tycho compiler.
Disable freeBuilder integration test for Eclipse since there are some problems in the second round of annotation processing (no ModelElementProcessor(s) are found)
* Move classes from mapstruct-common into mapstruct
* Use Java 8 @Repeatable for @Mappings and @ValueMappings in the mapstruct module
* Add relocation for mapstruct-jdk8 to mapstruct
* Use of 1.8 source and target versions from parent POM
* Update documentation to match
* Update versions of some maven plugin crashing build on Java 8
* Drop JDK 6 & 7 support in integration tests
* Remove mapstruct-common module (it was never deployed to Central)
* Don't run the ProtobufBuilderTest with the processor_plugin_java8 and eclipse_jdt_java_8 (processor plugin runs before the proto java classes are created and the eclipse plugin has some bug)
* Include *.proto for license checks
