Version information omitted from MANIFEST.MF in antlr-4.5.1-complete.jar

[RedTailedHawk]

Several properties have been omitted from META-INF/MANIFEST.MF in antlr-4.5.1-complete.jar. I noticed this when I added 4.5.1 to the ANTLR plugin for Eclipse -- it shows null in the Version column (screenshot attached).

Here's what I'm seeing in the file:

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Built-By: parrt
Created-By: Apache Maven 3.3.3
Build-Jdk: 1.8.0_60-ea
Main-Class: org.antlr.v4.Tool

And here's what's in the MANIFEST.MF for 4.5:

Manifest-Version: 1.0
Implementation-Vendor: ANTLR
Implementation-Title: ANTLR 4 Tool
Implementation-Version: 4.5
Implementation-Vendor-Id: org.antlr
Build-Jdk: 1.6
Built-By: parrt
Created-By: http://www.bildtool.org
Main-Class: org.antlr.v4.Tool

Could we get the missing properties added to the 4.5.1 jar packaging?

Thanks.
