Detailed version info within both tarball and within jar-files, and possible version-naming
of jars
---------------------------------------------------------------------------------------------------

                 Key: AMQ-1041
                 URL: https://issues.apache.org/activemq/browse/AMQ-1041
             Project: ActiveMQ
          Issue Type: Improvement
    Affects Versions: 4.1
         Environment: n/a
            Reporter: Endre Stølsvik


I can't find a file detailing which exact version of activeMQ I've uncompressed.

The actual 4.1 tarball currently have a filename "apache-activemq-4.1-incubator-SNAPSHOT",
not including anything more specific.

Inside the tarball there's nothing detailing what exact version we're at. The same goes for
the jar-files themselves.

*NOTE:* All this "as far as I can see" - I might have missed the obvious spot. If so, sorry.

Inside the "full jar", the META-INF/MANIFEST.MF just states:
{code}
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: chirino
Build-Jdk: 1.5.0_06
{code}

The information in these files are the information that will show up in the java.lang.Package
object for the Classes that was loaded from the jar in question, and its methods getSpecification[Title|Vendor|Version]()
and getImplementation[Title|Vendor|Version]() - which is nothing for activemq due to this
info completely missing.

In comparison, here's a bunch of better manifests:

Log4j: "log4j-1.2.12.jar" (note the version in the jar-name too, which is perfect) (This MANIFEST
file have missing date and Spec-triplet):
Manifest-Version: 1.0
{code}
Ant-Version: Apache Ant 1.6.4
Created-By: 1.3.1_16-b06 (Sun Microsystems Inc.)

Name: org/apache/log4j/
Implementation-Title: log4j
Implementation-Version: 1.2.12
Implementation-Vendor: "Apache Software Foundation"
{code}

And here's the spring jar actually included with the activemq distro (2.0), which is called
"spring-2.0.jar" (has missing date, spec-triplet):
Manifest-Version: 1.0
{code}
Ant-Version: Apache Ant 1.6.5
Created-By: 1.5.0_08-b03 (Sun Microsystems Inc.)
Implementation-Title: Spring Framework
Implementation-Version: 2.0
Spring-Version: 2.0
Premain-Class: org.springframework.instrument.InstrumentationSavingAgent
{code}

Here's a version of JGoodies Looks, which has the best MANIFEST.MF file of the lot (it defines
both Spec and Impl, perfect). The file's name is "looks-2.0-beta.jar". (The last piece of
information that would have been *nice* is explicit build-date, but presumably the date mentioned
in "Implementation-Version" is it (this is also definately the _correct_ thing to do).):
{code}
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.5
Created-By: 1.5.0_06-b05 (Sun Microsystems Inc.)
Built-By: Karsten
Specification-Title: JGoodies Looks API Specification
Specification-Vendor: JGoodies Karsten Lentzsch
Specification-Version: 2.0
Implementation-Title: JGoodies Looks
Implementation-Vendor: JGoodies Karsten Lentzsch
Implementation-Version: 2.0-beta 2006-01-29 10:40:27
{code}


*In addition*, it would be good if one of the txt-files of the root in the tarball included
all this information, and more. Everything about the build and its environment is nice to
have, including but not limited to all versions, checkout date, build date, full environment,
user, OS, OS-version, JVM-version - the lot.
