[jira] [Commented] (MNG-6521) remove deprecated main attributes
from generated MANIFEST
[ https://issues.apache.org/jira/browse/MNG-6521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16691964#comment-16691964 ]
Michael Osipov commented on MNG-6521:
-------------------------------------
Interesting, but the attributes aren't read through code anymore. They are solely for humans, aren't they? It does not hurt to have them by now, does it?
> remove deprecated main attributes from generated MANIFEST
> ---------------------------------------------------------
>
> Key: MNG-6521
> URL: https://issues.apache.org/jira/browse/MNG-6521
> Project: Maven
> Issue Type: Improvement
> Components: Artifacts and Repositories
> Affects Versions: 3.6.0
> Reporter: Franz van Betteraey
> Priority: Minor
>
> 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.
