  <description>
    This an Ant build file to automate the release process of
    Apache Slider (incubating).

    It wraps the core maven build and package commands with the
    operations needed to actually publish the artifacts, generate
    email announcements, etc.

    Requirements
    -all the various build tools are installed and on the path
    -you have git installed

    properties to set in ../release.properties

    slider.release.version=0.91.0
    slider.develop.version=0.92-SNAPSHOT
    release.jira=SLIDER-1014
    release.rc.suffix=-RC1

    # needed for announcements
    release.jira.version
    staging.repository

    #optional
    mvn.extra.args  : anything for maven
    git-check-unmodified.disabled : set this property to skip checking for unmodified
      files and halting the build if so (primarily for developing the release.xml build)
    git.version : the checksum to use in email announcements. Will need to be manually set
      if the git show-ref command is returning multiple checksums

      ==============================================================

      1. With your ASF username and LDAP password, Log in to
         https://repository.apache.org/index.html
      2. Go to "Staging Repositories":
         https://repository.apache.org/index.html#stagingRepositories
      3. Search for the `orgapacheslider` repository with the highest number
      4. Select it
      5. Browse the content, verify the version number is what you want.
      6. Hit the "close" button (top of list).
         This will fail if it doesn't meet the ASF criteria
      7. Wait for the close process to complete.
      8. Get the name of the closed staging repository (e.g. orgapacheslider-1010)
         set the property nexus.staging.repository to his value
      9. Execute:
           ant -f bin/release.xml generate-vote-text

The Apache Slider team is proud to announce Apache Slider incubation release version ${slider.release.version}

Apache Slider (incubating) is a YARN application which deploys existing distributed applications on YARN,
monitors them, and makes them larger or smaller as desired - even while the application is running.

The release artifacts are available at:
http://www.apache.org/dyn/closer.cgi/incubator/slider/${slider.release.version}/

To use the artifacts, please use the following documentation:
http://slider.incubator.apache.org/docs/getting_started.html
${common.links}

We would like to thank all the contributors that made the release possible.

Regards,
  ${asf.user} on behalf of the Apache Slider (incubating) team

DISCLAIMER

Apache Slider is an effort undergoing incubation at The Apache Software Foundation (ASF),
sponsored by the Apache Incubator PMC. Incubation is required of all newly accepted projects
until a further review indicates that the infrastructure, communications, and decision making
process have stabilized in a manner consistent with other successful ASF projects. While incubation
status is not necessarily a reflection of the completeness or stability of the code, it does indicate
that the project has yet to be fully endorsed by the ASF.
