----------------------------------
> Update description and parameters of --compress to reflect JDK21 changes
> ------------------------------------------------------------------------
>
> Key: MJLINK-77
> URL: https://issues.apache.org/jira/browse/MJLINK-77
> Project: Maven JLink Plugin
> Issue Type: Task
> Reporter: Benjamin Marwell
> Assignee: Benjamin Marwell
> Priority: Major
> Fix For: 3.2.0
>
>
> Starting from Java 21, the allowed parameters for {{compress}} have changed, and the old ones are suspect to removal:
> {code:java}
> $ jlink --help
> […]
> --compress <compress> Compression to use in compressing resources:
> Accepted values are:
> zip-[0-9], where zip-0 provides no compression,
> and zip-9 provides the best compression.
> Default is zip-6.
> Deprecated values to be removed in a future release:
> 0: No compression. Equivalent to zip-0.
> 1: Constant String Sharing
> 2: Equivalent to zip-6.
> {code}
> Thus, the current jlink-plugin is incompatible with Java 21:
> {code:java}
> /**
> * Here you can define the compression of the resources being used. The command line equivalent is:
> * <code>-c, --compress=level></code>. The valid values for the level are: <code>0, 1, 2</code>.
> */
> @Parameter
> private Integer compress;
> {code}
