What's in Maven 3.0 for users?


December 22, 2010 By Bentmann Benjamin

Asking the Maven issue tracker for all the changes or fixes that contribute to our freshly released Maven 3.0, one ends up with about 420 issues. While this is a rather large number, most of these issues deal with regressions we encountered and fixed during refactoring of the internals. But those issues are uninteresting to users that consider upgrading from Maven 2.x and want to know what’s the delta to 3.0.

The primary source of information for this delta are the compatibility notes and the plugin compatibility matrix.  These documents focus on changes that could negatively affect existing builds due to stricter behavior of Maven 3.0, but we also managed to implement a few general improvements here and there.

Maven 3 offers "better stability and performance"


October 16, 2010 By hloney

The Sonatype team is thrilled about the release of Maven 3.0, and it seems we’re not the only one.  Alex Handy from Software Development Times writes about the not only the improvments and new features that the user will see with Maven 3.0, but also about the changes made behind the scenes that will improve Maven’s performance and integration down the line.

Maven 3 offers better stability and performance, but the biggest changes won’t be noticed by users. Under the hood, a great deal of work was done to prepare Maven for a future of building OSGi applications and using dynamic languages to script the build process.

Apache Maven 3.0 has landed!


October 8, 2010 By Jason van Zyl

Apache Maven 3.0 has landed, but it’s really just the beginning. The work that Sonatype has done to bring Maven 3.0 to fruition is substantial. It’s been hard, it’s taken a lot of Sonatype’s time and resources, but we’re glad we did the work and we see this as a new beginning for Maven. We will, of course, keep working on Maven but with the release of Maven 3.0 Sonatype will, at least for a little while, turn an eye to Maven’s Eclipse-focused cousins, the Maven Shell, Polyglot Maven, and Hudson.

We have work to do on Tycho to get it fully setup for the parallel IP process at Eclipse, we will soon start a very intensive set of iterations to bring the M2Eclipse core to a 1.0 state, and we have committed within Sonatype to move M2Eclipse to the Eclipse Foundation. The M2Eclipse project at Eclipse has been in suspended animation for a while but we plan to work toward getting M2Eclipse into the release train and have Indigo be the first Eclipse distribution to ship with Maven capabilities. Tycho and M2Eclipse will also be a lot of work, but I think Sonatype has demonstrated that we’re committed to making these projects work and can deliver as we’ve shown with Maven 3.0.

There will be a release fairly soon of the Maven Shell, I will be starting a new phase of work on Polyglot Maven, and I’ll also be talking about concretely what Sonatype plans to do around Hudson — and what we’ve already done. Once we get a few more of the projects we’re working on to a healthy state we will begin the dialog with the community about what features users are looking for in future versions of Maven and related tools.

The Maven community owes a special thanks to Benjamin Bentmann, who has worked consistently and persistently for a long time on Maven 3.0. He has been amazingly responsive in applying fixes for reported issues, and has set the bar very high for the quality of a open source project. We have an enormous number of integration tests and without a doubt, Benjamin really has made this the best version of Maven we’ve ever had. I’d also like to thank Igor Fedorenko who is responsible for Tycho, along with all the changes he made to Maven core to allow its dynamic adaptation, as well as putting in place the performance framework for Maven 3.0. And Maven users can also thank Oliver Lamy for making sure the Maven Site Plugin is compatible with Maven 3.0.

Please try Maven 3.0 RC1!


September 16, 2010 By Jason van Zyl

We are very close to Maven 3.0! In preparation for the release we are entering the RC phase Sonatype is seeking the Maven user community’s help to discover regressions since Maven 2.x so that we can make the necessary provisions to correct any problems and push Maven 3.0 final out on schedule.

We know as the RCs are released more people will be trying Maven 3.x and feedback is critical. We obviously cannot fix your problem if you do not report the problem. Sonatype has two full-time people working on fielding the found issues so this is your chance to make sure Maven 3.0 final works for your projects. Sonatype has made a great deal of effort putting in place unit tests, integration tests, and performance tests for the core and the core plugins, so we’re ready for the feedback and will correct anything we find quickly.

Anyone interested in taking a preview of the upcoming release for a test drive can get source and binary bundles from this URL:

https://repository.apache.org/content/repositories/maven-030/org/apache/maven/apache-maven/3.0-RC1/

Note that this is a staged release and we will keep re-staging while we find serious regressions, but we want to get users into this cycle of testing the RCs as soon as possible. Once we get past anything nasty we will release the final RC1.

Before reporting any issues found during testing, please be sure to have a close look at the compatibility notes for Maven 3.x:

https://cwiki.apache.org/confluence/display/MAVEN/Maven+3.x+Compatibility+Notes

If you encounter unexpected build issues, please fill a report in JIRA that provides sufficient information to reproduce and analyze the issue:

http://jira.codehaus.org/browse/MNG

The fixes contained in this release candidate since the 3.0-beta-3 release can also be seen in JIRA:

http://jira.codehaus.org/secure/ReleaseNote.jspa?atl_token=PRIR5ueW-i&version=13142&styleName=Text&projectId=10500&Create=Create

It’s still possible to make our intended Maven 3.0 final release on October 1st, but we need your help!

Thanks!

Sonatype's June Newsletter


June 10, 2010 By hloney

Catch up on everything we’ve been up to in the past few weeks in the Sonatype newsletter.   In this edition we highlight the release of Apache Maven 3.0 beta-1.  A major goal of Maven 3.0 is to be compatible, to the extent possible, with existing plugins and projects designed for Maven 2.x. You can read more about Maven 3.0 at http://maven.apache.org/.

The June newsletter also previews some upcoming webinars taking place on June 10 and June 24.  These free webinars cover the Developer Onboarding feature of Maven Studio for Eclipse.  Among other features, Maven Studio for Eclipse will get new developers up and running on a project within minutes.  Stop wasting time and money by spending days training developers on new projects.

Sonatype has added some exciting new events to our schedule, including the Maven Meetup and DemoCamp happening June 16 in Guelph, Ontario.  For all of this info and more, check out the latest edition of the Sonatype newsletter.
