Release instructions

Prerequisites

  • use Java 9+ for making release. Make sure the JAVA_HOME environment variable is set to the correct JDK directory and exported in your terminal

  • ensure that all pom.xml files list the same version, update them if necessary to yyyy.mm.0-SNAPSHOT (check correct patch level)

  • in the moa.core.Globals class, update the versionString variable to match the upcoming version

  • in the weka-package/Description.props file, ensure that the following properties have been updated and aligned with the upcoming version:

    • Version (yyyy.mm.0, check correct patch level)
    • Date
    • PackageURL

  • ensure that all code has been committed/pushed

Deploy to Maven Central

  • Ensure your GPG signing key and Sonatype credentials are available in your Maven settings.xml file (found at either ~/.m2/ or /usr/share/maven/conf/). You can check the settings have been applied correctly by running the command:

    mvn help:effective-settings

  • For more information, follow the instructions at the following pages:

    https://blog.sonatype.com/2010/01/how-to-generate-pgp-signatures-with-maven/ https://blog.sonatype.com/2010/11/what-to-do-when-nexus-returns-401/

  • Publish your public GPG signing key to the keyserver at keyserver.ubuntu.com

  • Run the following maven command (from the top-level MOA directory), which will automatically use the current version present in the pom.xml files and then increment it after the release has succeeded.

    mvn --batch-mode release:prepare release:perform

  • Log into https://oss.sonatype.org

  • Select Staging Repositories, scroll right to the bottom of the list and look for a repository called something like nzacwaikatocmsmoa-XYZ. Select this repository via the check-box.

  • Subsequently Close and then Release the artifacts. NB: It may take a few minutes before the Release button becomes available, as the system is flagging all the artifacts from the staging repo. When releasing, leave the Drop Repository check-box ticked.

  • Perform a git push

  • Check the following URL after 15-20min (sync with Maven Central only happens every 15min or so) to see whether they artifacts are indeed available from Maven Central (the search index at https://search.maven.org/ only gets updated every few hours):

    http://central.maven.org/maven2/nz/ac/waikato/cms/moa/

Generate release files

MOA

  • update the parent version in release.xml to the just released version, i.e., yyyy.mm.0 (without the -SNAPSHOT suffix, check correct patch level)

  • execute the following commands (top-level directory)

    mvn clean install -DskipTests=true latex:latex
mvn -f release.xml prepare-package deb:package install

Weka Package

  • go into the weka-package directory

  • update the parent version in update_libs.xml to the just released version, i.e., yyyy.mm.0 (without the -SNAPSHOT suffix, check correct patch level)

  • execute the following command to update libraries in the lib directory

    mvn -f update_libs.xml clean package

  • execute the following command (replace X.Y.Z with actual version of MOA, eg yyyy.mm.0, check correct patch level)

    ant -f build_package.xml -Dpackage=massiveOnlineAnalysis-X.Y.Z clean make_package

Publish release

  • create new release tag on Github (tag version yyyy.mm.0, release title MOA yy.mm.0) and upload the generated MOA release zip file from the top-level target directory and the zip file from the weka-package/dist directory

  • email Mark Hall (mhall at waikato.ac.nz) the link to the Weka package zip file to upload to the central Weka package repository on Sourceforge.net

Finish up

  • synchronize the parent version in release.xml and update_libs.xml to match the new version in the top-level pom.xml file; this is required to make the snapshots work (jenkins, download);

  • ensure that the Y in X.Y.Z is two digits in all pom.xml files, release.xml and update_libs.xml; the automatic increment will strip a leading zero.

  • commit/push all changes
