In order to avoid certain staleness problems with gradle's "isolating" annotation processing model, some features had to be removed.

• Remove the Converter annotation.
• The converter attribute must now point to a static member class of the command class (see note).
• Forbid inheritance of abstract methods.

Note: Effectively, it is still possible to define a "standalone" converter class, by writing a small static inner class which implements Supplier<StringConverter<X>> and returns an instance of the "real" converter class from its get method. For example, see how BigIntegerConverter is used in CustomConverterCommand.

• allow abstract overrides
• improve parameters-validation error message
• forbid StringConverter of Optional
• improve invalid position error message

• fix converter error message
• use either 1.5

• use either 1.3

• use either:1.2
• stop including either in the compiler jar

• depend on either:1.1
• stop using javadoc as input for usage documentation

• depend on io.github.jbock-java:either:1.0
• new attribute generateParseOrExitMethod
• remove attributes atFileExpansion and helpEnabled; configure the ParseRequest instead
• fix formatting in generated character converter
• improve at-file syntax: ignore all empty lines, allow quoting
• add support for alternative Optional types: vavr
• the generated parse method now takes an argument of type ParseRequest
• use 4-space indentation for all source files

jbock 5.1 "midsummer edition"

• removed ansi attribute from Command, it is now a runtime config in StandardErrorHandler
• remove redundant attribute exithook from StandardErrorHandler; custom exit logic can now be implemented without this; see implementation of generated method parseOrExit
• add attribute unixClustering to CommandModel
• fix: atFileExpansion = false didn't compile
• fix: potential infinite loop at compile time, in EnumName logic
• allow additional tokens after at file expansion
• refactoring: avoid lambdas in generated method StatefulParser#build, extract convert logic for enums, File and char to inner classes

• Changed the maven group name to io.github.jbock-java
• Renamed the artifacts: "jbock-annotations" -> "jbock" (aka "core"), "jbock" -> "jbock-compiler".
• moved the Either library into core
• add runtime model of the annotated class (net.jbock.model.CommandModel)
• parse now returns an Either
• rename the generated class, "*_Parser" -> "*Parser"
• SuperCommand is now an attribute
• add the atFileExpansion attribute
• add the unixClustering attribute
• runtime config, like terminalWidth, works differently (see implementation of parseOrExit)

• new attribute 'ansi'
• please note that jbock requires java 11, since version 4.3.000
