Passing extendedVariables Property using mvn -D Commandline Option

[vhochstein]

Just a question..

./mvnw generate-resources -DextendedVariables=releaseTrain=20.11

Fails with following exception:
Unable to parse configuration of mojo se.bjurr.gitchangelog:git-changelog-maven-plugin:1.63:git-changelog for parameter extendedVariables: Cannot assign configuration entry 'extendedVariables' with value '${extendedVariables}' of type java.lang.String to property of type java.util.Map

Do you know correct syntax to pass extendedVariables Map using Commandline ?

No dont know.

@tomasbjerre I ve searched the web a little bit and asked corresponding question in Apache maven plugin group.

and I would like to share my findings with you:

@Parameter(property = "extendedVariables", required = false) private Map extendedVariables;

cannot be set by command line interface.. however, at least I found a post which came up with following solution (basically it means accepting map as a String[] and converting it to a map on your own:
@Parameter(property = "extendedVariables", required = false) private String[] mapEntries; private Map extendedVariables;

@Override public void execute() throws MojoExecutionException { map = Arrays.stream( mapEntries ).collect( Collectors.toMap( s -> s, s -> s ) );

What do you think about it. ( it would be great to have that feature for my purposes....=
