# Generates a pom.xml with a haoop1 or a hadoop2 suffix which can
# then be used for generating hadoop1 or hadoop2 suitable hbase's
# fit for publishing to a maven repository. Use these poms also
# making tarballs to release. The original pom.xml is untouched.
#
# This script exists because we cannot figure how to publish
# into the local (or remote) repositories artifacts that can be
# used by downstream projects (with poms describing necessary
# includes). See HBASE-8224 and HBASE-8488 for background.
#
# Generation is done by replacing values in original pom and
# enabling appropriate profile using the '!' trick in the
# hbase.profile property (this is fragile!) so no need to specify
# profile on the command line. The original pom.xml should be
# what we maintain adding in new depdencies, etc., as needed.
# This script should make it through most any change to the
# original.
#
# Here is how you would build an hbase against hadoop2 and publish
# the artifacts to your local repo:
#
# First run this script passing in current project version and what
# version you would like the generated artifacts to have. Include
# either -hadoop1 if built against hadoop1 or -hadoop2 if build against
# hadoop2. These substrings are expected as part of the new version.
#
# $ bash -x ./dev-support/generate-hadoopX-poms.sh 0.95.2-SNAPSHOT 0.95.2-hadoop2-SNAPSHOT
#
# This will generate new poms beside current pom.xml made from the
# origin pom.xml but with a hadoop1 or hadoop2 suffix dependent on
# what you passed for a new version. Now build passing generated
# pom name as the pom mvn should use. For example, say we were building
# hbase against hadoop2:
#
#$ mvn clean install -DskipTests -f pom.xml.hadoop2
#
# TODO: Generate new poms into target dirs so doesn't pollute src tree.
# It is a little awkward to do since parent pom needs to be able to find
# the child modules and the child modules need to be able to get to the
# parent.

# replace the version string in all poms, we change modules
# to include reference to the non-standard pom name, we
# adjust relative paths so child modules can find the parent pom,
# and we enable/disable hadoop 1 and hadoop 2 profiles as
# appropriate removing a comment string too. We output the

Undo the tarball and make sure it looks good. A good test for the src tarball being 'complete' is to see if
you can build new tarballs from this source bundle. For example:

<para>Now we are into the making of the hadoop1 and hadoop2 specific binary builds. Lets do hadoop1 first.
First generate the hadoop1 poms.
<note>
<para>We cannot use maven to publish what is in essence two hbase artifacts both of the same version only
one is for hadoop1 and the other for hadoop2. So, we generate hadoop1 and hadoop2 particular poms
from the checked-in pom using a dev-tool script and we run two builds; one for hadoop1 artifacts
and one for the hadoop2 artifacts.
</para>
</note>
See the <filename>generate-hadoopX-poms.sh</filename> script usage for what it expects by way of arguments.
You will find it in the <filename>dev-support</filename> subdirectory. In the below, we generate hadoop1 poms with a version
of <varname>0.96.0-hadoop1</varname> (the script will look for a version of <varname>0.96.0</varname> in the current <filename>pom.xml</filename>).
<programlisting>$ ./dev-support/generate-hadoopX-poms.sh 0.96.0 0.96.0-hadoop1</programlisting>
The script will work silently if all goes well. It will drop a <filename>pom.xml.hadoop1</filename> beside all <filename>pom.xml</filename>s in all modules.
</para>
<para>Now build the hadoop1 tarball. Note how we reference the new <filename>pom.xml.hadoop1</filename> explicitly.
We also add the <varname>-Prelease</varname> profile when building; it checks files for licenses and will fail the build if unlicensed files present.
<para>Now lets build the binary tarball.
Add the <varname>-Prelease</varname> profile when building; it checks files for licenses and will fail the build if unlicensed files present.
Do it in two steps. First install into the local repository and then generate documentation and assemble the tarball
(Otherwise build complains that hbase modules are not in maven repo when we try to do it all in the one go especially on fresh repo).
It seems that you need the install goal in both steps.

<para>I'll tag the release at this point since its looking good. If we find an issue later, we can delete the tag and start over. Release needs to be tagged when we do next step.</para>
<para>Now deploy hadoop1 hbase to mvn. Do the mvn deploy and tgz for a particular version all together in the one go else if you flip between hadoop1 and hadoop2 builds,
you might mal-publish poms and hbase-default.xml's (the version interpolations won't match).
<para>Now deploy hbase to the apache maven repository.
This time we use the <varname>apache-release</varname> profile instead of just <varname>release</varname> profile when doing mvn deploy;
it will invoke the apache pom referenced by our poms. It will also sign your artifacts published to mvn as long as your settings.xml in your local <filename>.m2</filename>
repository is configured correctly (your <filename>settings.xml</filename> adds your gpg password property to the apache profile).
<programlisting>$ MAVEN_OPTS="-Xmx3g" mvn -f pom.xml.hadoop1 deploy -DskipTests -Papache-release</programlisting>
The last command above copies all artifacts for hadoop1 up to a temporary staging apache mvn repo in an 'open' state.
We'll need to do more work on these maven artifacts to make them generally available but before we do that,
lets get the hadoop2 build to the same stage as this hadoop1 build.

<para>The script <filename>dev-support/make_rc.sh</filename> automates alot of the above listed release steps.
