Description

The MANIFEST implementation entries can be generated by using the 'addDefaultImplementationEntries' of the Apache Maven Archiver configuration
(http://maven.apache.org/shared/maven-archiver/index.html#class_manifest) like this:

    <archive>
        <manifest>
            <addDefaultImplementationEntries>true</addDefaultImplementationEntries>
        </manifest>
    </archive>
    
This will add

    Implementation-Title: ${project.name}
    Implementation-Version: ${project.version}
    Implementation-Vendor-Id: ${project.groupId}
    Implementation-Vendor: ${project.organization.name}
    Implementation-URL: ${project.url}

to the MANIFEST.MF file. But

    Implementation-Vendor-Id and
    Implementation-URL

are deprecated by now (at least since Java 8 as seen here):
https://docs.oracle.com/javase/8/docs/technotes/guides/jar/jar.html#Main_Attributes

In the Java 11 jar Manifest Specification they are not mentioned anymore.
https://docs.oracle.com/en/java/javase/11/docs/specs/jar/jar.html#manifest-specification

Thus I guess they also should be removed while generating the main implementation entries by the Maven Archiver.
