Maven 3.0 is here!
This release features a Maven API for component configuration,
updated default plugin versions and an extended core artifact
filter. The full list of changes and bug fixes is available at the
Maven 3 targets backwards compatibility with Maven 2, in
addition to allowing safe embedding and improving usability and
performance. However, there are some issues with Maven 2
compatibility, which are discussed in detail at the Maven 3.x Compatibility Notes document. Some
incompatibility issues revolve around Maven 3’s removal of support
for profiles outside of the POM or the settings.xml, and the
removal of reporting related code from the core of Maven 3.
Please note that if you wish to try the new parallel build
feature, the Maven team advise reading the ‘Guide on Parallel Builds‘ documentation.
Parallel build analyses a project’s dependency graph and schedules
modules that can be built in parallel, according to said dependency
graph. This is an experimental feature – but Maven 3 comes with a
“more experimental mode,” called ‘Weave’ which builds the reactor
phase-by-phase in dependency order. This is instead of completing
the full modules before moving onto the next. Information on Weave
is also available at the ‘Guide to Parallel Builds‘ document.
Please note that the Maven 3 core release is made independently
of related Maven plugins. A list of available plugins is
available from the Maven website.
According to Jason van Zyl’s blog post, now the Maven 3 release is out the
door, the team will focus on the Maven Shell, Polyglot Maven, and
Hudson projects. Specifically, the Maven team will work to get
Tycho fully setup for the Eclipse parallel IP process, and will
move M2Eclipse to the Eclipse Foundation and bring the core to a
1.0 state. Jason van Zyl is aiming for M2Eclipse to join the
Eclipse release train, making Indigo the first Eclipse distribution
to ship with Maven capabilities. He also pledges a release of the
Maven Shell “fairly soon” and a “new phase of work” on Polyglot
