Is there any way to do analysis of 3rd party java library jars.
There huge set of jars being used by application of obsolete version but stable.
Is there any way to find out report which shows what are my repository version is and what is market latest jars...
I just don't want to keep version as latest and product stability is a very important factor.
Going through each and every jar and do research is really cumbersome.
Is there any better method ?
You can use versions plugin.
mvn versions:display-dependency-updates
This will scan a project's dependencies and produces a report of those dependencies which have newer versions available.

Can anyone please tell me why eman project was dropped from opendaylight Oxygen release. Or is there any other feature which can do the same job as done by eman.
The eman project along with some other projects lost their contributors and are no longer actively maintained by anyone and thus were not included in the release. You could try posting to the eman-dev mailing list to see if anyone is still subscribed. You can always download the project and build it yourself. Perhaps you would like to reboot the project and maintain it - the ODL community would welcome your contributions.

I have an opensource Go project. Some commits were causing failures on 386, but I didn't know because my builds were configured incorrectly.
I'm now testing against 386 using Travis. Which GOARCH/GOOS/Go version combinations should opensource projects test against? I want meaningful coverage but I also want fast builds.
You can see which Go binary release stable version combinations (Version/GOOS/GOARCH) are supported by Go downloads.
See Go Downloads
You may limit it to Go first-class ports.
See First class ports, PortingPolicy.
You should conform to the Go release policy.
See Release Policy, Go Release History
You should consider premptively testing against release candidates, and, perhaps betas and devel.

we all know that there is community supporting maven and since maven has some advanced features so most people recommend as building tool and gradle is in picture too but is using ant today will be considered as old fashioned or it still gives same competition that it used to be?
did maven has achieved more then ant or ant is still alive?
Ant is the grandaddy of the all, starting out as a Java version of "make" (an even older build tool). Along came Maven 1.0 (which we all pretend never existed) to be replaced by Maven 2.0. For a brief time the Java world was split between those who understood the importance of dependency management and those who didn't. Eventually all tools now copy what Maven pioneered and we now have Gradle, a modern build tool built on the shoulders of giants :-)
So cool kids Gradle. Most Java developers are using Maven (frequently bundled and hidden away by their Eclipse IDE) and old school release engineers still have productive careers maintaining corporate applications that use Ant.

I've always wondered what these are. I've read the Maven documentation about this and I don't think I really understand it. Could somebody please explain this? Thanks.
Optional dependencies are used when it's not really possible (for whatever reason) to split a project up into sub-modules. The idea is that some of the dependencies are only used for certain features in the project, and will not be needed if that feature isn't used. Ideally, such a feature would be split into a sub-module that depended on the core functionality project...this new subproject would have only non-optional dependencies, since you'd need them all if you decided to use the subproject's functionality.
However, since the project cannot be split up (again, for whatever reason), these dependencies are declared optional. If a user wants to use functionality related to an optional dependency, they will have to redeclare that optional dependency in their own project. This is not the most clear way to handle this situation, but then again both optional dependencies and dependency exclusions are stop-gap solutions.

Is there a standard way for finding maven entries for any project? For eg if I talk about Spring MVC. Do I need to go the Spring website and find a section there or is there some other standard procedure using which I can find the entries I need to make ?
No, You can find them in the ordinary maven repositories:
http://mvnrepository.com/
http://search.maven.org/
You search for the artificat you want, and get the pom info to include in your dependencies
I just google "maven" and the package name. Some artifacts are only made public in company repos.
I search com.x.y.z maven coordinates on google and almost every time I get the results.
