[fedora-java] XMvn 1.0.0 release notes

[Mikolaj Izdebski]

What's new in XMvn 1.0.0

* Major features

  * Flexible repositories

    Since version 1.0.0 XMvn has a new way of configuring
    repositories from which artifacts are resolved and to which they
    are installed.  Several aspects of artifact resolution which
    were hardcoded in previous versions of XMvn are configurable
    since version 1.0.0.

  * Classifiers and extensions

    Previous versions of XMvn lacked support for artifact
    classifiers and for artifact extensions other than <<<jar>>> and
    <<<pom>>>.  Since version 1.0.0 XMvn supports resolution and
    installation of artifacts with any classifier and extension.

  * Compatibility versions

    Although previous versions were able to resolve versioned
    artifacts (also knows as compatibility versions), there was no
    support for installing versioned artifacts.  Since version 1.0.0
    XMvn fully supports compatibility versions -- it is able to both
    resolve and install versioned artifacts.

  * Installing artifacts not produced in reactor

    Sometimes there is a need to install artifacts not produced in
    Maven reactor, but generated by other means, like custom script
    or other build system.  Since version 1.0.0 XMvn allows
    installation of such artifacts along with artifacts produced by
    Maven build.

  * Artifact namespaces

    XMvn 1.0.0 allows artifacts to have namespaces, which limits
    possible name clashes and allows several versions of the same
    artifact to be installed more easily without the need to use
    compatibility versions.  This feature can be used to implement
    support for software collections.

* Minor features

  * Improved performance of resolver

    Reading depmap fragments is the dominant operation when running
    short-living tools like XMvn Resolve or XMvn Subst.  Since
    version 1.0.0 depmaps are being read in parallel, which improves
    performance on multi-processor systems.

  * Improved build-requires generator

    Dependency did not include all possible cases when generating
    build-requires.  This has been improved in XMvn 1.0.0.

  * Improved support for compatibility versions

    Versioned artifacts are now resolved in simpler and more obvious
    way.

  * Improved handling of Java versions

    Besides standard versions like 1.4 or 1.7 XMvn now recognizes
    other visioning schemes like 7.0 or 7, as well as <<<jsr14>>>
    and <<<cldc1.1>>>.

  * Improved error handling in command-line tools

    Command like tools now print better error messages and are less
    likely to print stack traces for user errors.

* Minor bugfixes

  * Possible concurrency bug when creating symbolic links

    Possible concurrency bug when creating symbolic links was
    avoided by using file system atomic operations, if supported by
    file system.
