# 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.
