>                 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&gt;</code>. The valid values for the level 
> are: <code>0, 1, 2</code>.
>      */
>     @Parameter
>     private Integer compress;
> {code}
