Dear Wayne, or whomever it may concern,
My maven project includes ImageJ with the following dependency:
<dependency>
<groupId>net.imagej</groupId>
<artifactId>ij</artifactId>
<version>1.54j</version>
</dependency>
But I note that version 1.54j, which supersedes 1.54h10 daily build does
not include the modified ImageListenerAdapter that includes:
default void imageSaved(ImagePlus imp) { }
Is there a reason why this being excluded from the versions stored in the
central maven repository?
Sincerely yours -- Michael Ellis
