[jira] [Commented] (LUCENE-5273) Binary artifacts in Lucene and Solr convenience binary distributions accompanying a release, including on Maven Central, should be identical across all distributions

    [ https://issues.apache.org/jira/browse/LUCENE-5273?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13791329#comment-13791329 ] 

Uwe Schindler commented on LUCENE-5273:
---------------------------------------

Just one question: Why unpack the whole lucene tgz? You can directly refer to JAR files from inside tar/zip by using zipfileset/tarfileset. So there is no need to unpack those files, just add them directly from their tar resource. I use a similar approach in forbidden, to extract stuff from IVY artifacts without copying and unzipping JAR files.

> As mentioned in various issues (e.g. LUCENE-3655, LUCENE-3885, SOLR-4766), we release multiple versions of the same artifact: binary Maven artifacts are not identical to the ones in the Lucene and Solr binary distributions, and the Lucene jars in the Solr binary distribution, including within the war, are not identical to the ones in the Lucene binary distribution.  This is bad.
> It's (probably always?) not horribly bad, since the differences all appear to be caused by the build re-creating manifests and re-building jars and the Solr war from their constituents at various points in the release build process; as a result, manifest timestamp attributes, as well as archive metadata (at least constituent timestamps, maybe other things?), differ each time a jar is rebuilt.
