Checklist: Release

1. Do one-time setup required for releasing.
2. Finish up any changes, close Jiras, assign Jiras to proper release(s).
3. Update the property in the main pom controlling the ISSUES-FIXED
4. NEW ! Update the parent-pom settings for API compatibility: previous version and compat.level
5. Update the READMEs and RELEASE-NOTES.
6. Announce on the dev list that you're doing a release so others can get any changes in, and also know not to be committing to trunk while you're in the middle of doing the release.
7. Make a new build directory for this release, and source control checkout the trunk or git clone the repo and switch to the branch (if needed). (svn "export" instead of checkout fails at a later commit step by the release plugin). This is so you can preserve the build for later upload of selected artifacts to the distribution spot.

   If instead you are building from an existing checkout, do a source control update to be sure the workspace is up-to-date.

8. Purge your local maven repository of artifacts being built by running in the top level directory you'll be building from:
   
   mvn dependency:purge-local-repository
   
   Note that this will immediately re-resolve the dependencies from the maven repositories you have configured.

   Note: this doesn't seem to work, as the purged items end up being needed by the recursive module build. So, instead, just go to the .m2 .../uima/ node and consider deleting that directory.

9. Do a full build with deploy of the (last) snapshot before release: mvn clean deploy -Papache-release
10. If retrying a release candidate, delete the old rc-xxx in svn xxx/tags/ or the git branch for the tag.
11. If retrying a release candidate, close (and drop as appropriate) any previous repository.apache.org staging repo

More details on next steps are here

Release one or more artifacts into the Apache Nexus staging repository. You can do multiple release:prepare/perform steps, with subsequent steps depending on the previous artifacts in their "release" version.

1. Do next steps in top release artifact (single module, or mult-module top project).

   Release one or more artifacts into the staging repo.

   1. Scan poms to be sure there are no unintentional -SNAPSHOTs
   .
   2. mvn release:prepare -DdryRun and diff the resulting poms to verify nothing unintentional is dropped or updated incorrectly
   For multi-module projects, where all the submodules have the same version, use:
   mvn release:prepare -DdryRun -DautoVersionSubmodules.
   3. mvn release:clean to restore projects
   4. mvn release:prepare [-DautoVersionSubmodules]. Try to accept the default suggestions for names; you might change the source control tag to include a "-rc1" suffix indicating a release candidate number.
   5. mvn release:perform
2. Repeat above steps for all things being released in one go (not already in an aggregate).
3. login to https://repository.apache.org using your Apache LDAP credentials, find the staging artifact, and right click - "close" it after all things that are being included in this release are present.
12. If necessary, run mvn release:prepare on the eclipse update site. This will create the source control tag, and create the needed artifacts in the target/eclipse-update-site. No need to run release:perform because no artifacts from this are going to Maven central distribution.

    Note that the target/eclipse-update-site will have .svn files - don't delete these - they're needed when you decide to "publish" via comitting these to the release svn.

13. Copy any artifacts (together with their signings) to the staging spot. A suggested approach: Make a new dir in the build project, called svnUpload (or whatever), and copy the artifacts (from the build/target/checkout/target directory)(typically the bin/zip/tar and the source release and all the signature/checksums) into this dir. Then do the svn command:

    cd the-svnUpload-directory
    svn import -m "commit msg, e.g. uimaj-2.8.0 rc5" . https://dist.apache.org/repos/dist/dev/uima/uimaj/n.n.n-rc1/artifacts
    

    And do something similar for the eclipse update sub-site.

    Be sure to copy artifacts from the build-from tag spot, which should have a path like: ...[top level project]/target/checkout/target. Note this is not from [top level project]/target. Doing this will guarantee that you're posting the artifacts built from the tag (which could be different from the release:prepare build in /target if someone snuck in a svn commit at the right moment.)

14. Send [VOTE] message to dev list. List the staging repository that testers will need to add to their settings.xml files, and the distribution SVN repo link.
15. Post RESULT message
16. For Eclipse plugins, sign the jars.
17. Delete any artifacts from the staging repo that aren't supposed to go to Maven Central (if any). The uimaj build doesn't put the bin.zip or bin.tar artifacts on the staging repo, but other builds might need some cleanup.
18. Promote the release(s) from the staging repositories
19. Add the approved staged artifacts to the release/uima spot. This is https://dist.apache.org/repos/dist/release/uima/uimaj-x.y.z (replace the last with the thing being released). Assuming you previously promoted the release candidate to https://dist.apache.org/repos/dist/dev/uima/uimaj/xxx/yyy, you can use the command (modify the details, of course)

    svn copy https://dist.apache.org/repos/dist/dev/uima/uimaj/2.10.0-rc1/artifacts
            https://dist.apache.org/repos/dist/release/uima/uimaj-2.10.0 -m "release uimaj-2.10.0"
          

    If adding additional new directories to the target, use the --parent parameter to tell svn to create those.

    Do not add files like POMs which have line-endings, if they have signatures; the files added should be "binary" style files. (The line endings (if you build on windows) will be changed upon upload to svn, which will result in bad signatures).
20. Eclipse update sites:
    • If you a resetting the update subsite, do these steps:
      1. rename the update subsite to xxx-a.b.c-d.e.f where a.b.c is the first version and d.e.f is the last version. You do this via svn copy command in the dist.apache.org release spot. If you have a GUI tool like tortisesvn, you can use that.
      2. after the rename, wait until you see this in the archive.apache.org spot, then delete it from the dist.apache.org release svn. Although this will delete it on the apache mirror system, it will remain in the archive.apache.org spot.
      3. now, checkout the dist.apache.org release subsite, and modify it by deleting items, adding items, and modifying items in the working set. Then commit these changes so the current site reflects the new one.
    • Otherwise, the eclipse-update-sub-site project's output folder in the target directory should already be svn working copies, so you can commit these.

      Commit the target/xxxx/yyyy/features, .../plugins, and the artifacts/content jars and signatures.

      DO NOT COPY the dist...dev site, instead, use the build's update site with the signed jars, and just "commit" it.

      If using Windows and have tortise svn installed, cd to the target/eclipse-update-site/uimaj (or wherever your update site was built) and right click and say commit (and click the "all" selection to upload the new files).
21. Check the www.apache.org/dist/uima site using https://checker.apache.org/projs/uima.html
22. update the UIMA website docs/d with any generated docs, in a manner to minimize SVN space use, if possible. This includes: PDFs, HTML versions of docbooks plus the index.html; all go on the website under the uima.apache.org/d/ (non-SVN source) directory. Update the index.html as needed for the version.
23. Copy RELEASE_NOTES and issuesFixed, and maybe api-change-report from the .../target/checkout where the mvn release:perform was done from to the UIMA web site in doc/d/[project-version].
24. If using links to api change report, insert needed folders and copy api change report. For example, for uimaj: insert uimaj-core folder into .../d/uimaj-x.y.z and copy in the api change report from uimaj-core.
25. update the current-release folder, if in use. Do this by doing an svn copy from uima-website/docs/d/xxx-y.y.y to .../docs/d/xxx-current. It's convenient to use tortise-svn: navigate to the docs/d, select uimaxxx-y.y.y folder, and then right-click and pick copy to ... and specify docs/d/uimzxxx-current folder.
26. Update the downloads page of the web site, and the xdocs/stylesheets/project.xml for the new release.
27. Update Jira version info to reflect the release status and date
28. Log into https://reporter.apache.org/addrelease.html?uima and add release data (e.g. uimaj-2.10.0 2017-04-04).
29. Fixup the tag.
    • SVN: Fix the SVN tag for the release candidate if needed, removing any -rcXX, to indicate the release.
    • GIT: make a new tag for the release with the name rel/...tag-name.
      • git tag -m "proj-name-1.2.3 rcXXX released" rel/proj-name-x.y.z proj-name-x.y.z^{} The strange notation ^{} peels the annotated tag and returns a ref to the actual commit.
      • git push origin rel/proj-name-x.y.z This updates the remote repo with the new tag.

      • Merge the release branch (if one was made) into the main branch. You can use the github.com site to do this: make a pull request targeting the master, from the release branch, and after checks pass, accept the pull. Alternatively, you can pull from the release branch into the master in a local checkout, and push the result.

        If no release branch was made, then the maven release prepare/perform will have already updated the master to the next snapshot level.

30. After release appears on maven central, post an appropriate announce letter
31. Add a news item for the release
32. Tweet about the release
33. Add release to next Board report
34. Celebrate :-)
