Usage: release-build.sh <tag|publish-dist|publish-snapshot|publish-release>
Creates release deliverables from a tag or commit.
Argument: one of 'tag', 'publish-dist', 'publish-snapshot', or 'publish-release'
  tag               Prepares for release on specified git branch: Set release version,
                    update CHANGES and RELEASENOTES, create release tag,
                    increment version for ongoing dev, and publish to Apache git repo.
  publish-dist      Build and publish distribution packages (tarballs) to Apache dist repo
  publish-snapshot  Build and publish maven artifacts snapshot release to Apache snapshots repo
  publish-release   Build and publish maven artifacts release to Apache release repo, and
                    construct vote email from template

All other inputs are environment variables.  Please use do-release-docker.sh or
do-release.sh to set up the needed environment variables.  This script, release-build.sh,
is not intended to be called stand-alone, and such use is untested.  The env variables used are:

Used for 'tag' and 'publish' stages:
  PROJECT - The project to build. No default.
  RELEASE_VERSION - Version used in pom files for release (e.g. 2.1.2)
    Required for 'tag'; defaults for 'publish' to the version in pom at GIT_REF
  RELEASE_TAG - Name of release tag (e.g. 2.1.2RC0), also used by
    publish-dist as package version name in dist directory path
  ASF_USERNAME - Username of ASF committer account
  ASF_PASSWORD - Password of ASF committer account
  DRY_RUN - 1:true (default), 0:false. If "1", does almost all the work, but doesn't actually
    publish anything to upstream source or object repositories. It defaults to "1", so if you want
    to actually publish you have to set '-f' (force) flag in do-release.sh or do-release-docker.sh.

Used only for 'tag':
  YETUS_HOME - installation location for Apache Yetus
  GIT_NAME - Name to use with git
  GIT_EMAIL - E-mail address to use with git
  GIT_BRANCH - Git branch on which to make release. Tag is always placed at HEAD of this branch.
  NEXT_VERSION - Development version after release (e.g. 2.1.3-SNAPSHOT)

Used only for 'publish':
  GIT_REF - Release tag or commit to build from (defaults to $RELEASE_TAG; only need to
    separately define GIT_REF if RELEASE_TAG is not actually present as a tag at publish time)
    If both RELEASE_TAG and GIT_REF are undefined it will default to HEAD of master.
  GPG_KEY - GPG key id (usually email addr) used to sign release artifacts
  REPO - Set to full path of a directory to use as maven local repo (dependencies cache)
    to avoid re-downloading dependencies for each stage.  It is automatically set if you
    request full sequence of stages (tag, publish-dist, publish-release) in do-release.sh.

For example:
 $ PROJECT="hbase-operator-tools" ASF_USERNAME=NAME ASF_PASSWORD=PASSWORD GPG_KEY=stack@apache.org ./release-build.sh publish-dist
