Gradle 2.0 is here: sleek, speedy and supporting Java 8
Update includes a leaner code base and a host of new additions. There’s also an upgrade to Groovy 2.3.2.
In a significant milestone for the community
around it, build automation tool Gradle officially reached 2.0
status this week. With the extraction of many deprecated features
and APIs from the codebase,
Gradle 2.0 is a lean, mean work machine, and
promises to offer a good deal more flexibility than previous
incarnations of the software.
Regarding this wave of extinctions, note that
only features that have been formally marked as deprecated will be
excised, and generally only those features that have been
deprecated for at least two releases of Gradle – so no need to
sweat about broken compatibility in your recent builds.
Befitting for such a major release, Gradle 2.0
is characterised by more than its new backwards compatibility
baseline though. There’s the small matter of support for Java 8 for
one, which is fully primed and ready to leap into action, as soon
as you can be bothered to update.
Gradle 2.0 also introduces a new public API for
resolving “source” and “javadoc” JARs for JVM library components.
With this addition, Gradle can now offer single, dedicated APIs for
components and artifacts. The exposition of Ivy “Extra Info”
attributes enables a new class of advanced dependency management
use cases, and it’s now possible to use the SFTP protocol for
dependency consumption without the need for custom Ivy
There’s also been some quality control executed
on code plug-ins – to this end, Checkstyle 5.7, 2.0.3
Findbugs and PMD 5.1.1 are all fully supported.
Gradle 2.0 now uses Groovy 2.3.2 (released at the
beginning of May) for the compilation and running of build scripts
and plug-ins. In the spirit of object-oriented programming, these
are all reusable components. To hear more about the object-oriented
ethos, take a look at our interview with Guillaume Laforge, shot
shortly after the software’s 2.3 release, where he explains
just what it is that makes Groovy so fab.
