Instructions for making a Release:
Authors: Conor MacNeill
Stefan Bodewig
Magesh Umasankar
Antoine Levy-Lambert
Note: This document was adapted from the one created in the context of
releasing Ant 1.9.7. It assumes the first release created from
master will be 1.10.
Please interpret the branch names, tags, etc. according to
your context.
It reflects the way Stefan prefers to cut the release, parts of
this process haven't even been discussed on the dev list and may
change with later releases.
1. Propose a release plan for vote. This should set out the timetable for
the release under ideal circumstances.
In reality, you send a note to the list that you intend to cut the
release and wait for a few days whether anybody objects.
We haven't created extra branches for releases in a long time and
with out new 1.9.x LTS policy there is a permanent branch for
Java5 compatible releases anyway. So no extra branch for the
releases is needed.
This document assumes you are familiar with git
http://git-scm.com/book/en/v2/
may be a good guide if you are not.
2. Ensure you have all the external libraries that Ant uses in your
lib/optional directory. All dependencies are either provided by
JDK 1.8.0 or downloadable using
ant -f fetch.xml -Ddest=optional
To find out whether you have all the libraries you need, execute
the build with -verbose option and scan for lines beginning with
"Unable to load...".
3. We don't want tags for failed votes to end up on out branches so
the release is first created from a detached head.
Checkout the HEAD of the master branch as a detached head:
$ git checkout master^0
4. Make sure that your directory tree is clean by running git status.
Some tests leave behind leftovers which end up in the source
distribution otherwise.
5. Set the version number in several files to the required new
versions. These are:
* manual/cover.html (version should already be correct here)
* manual/credits.html (version should already be correct here)
* build.xml properties : project.version,manifest-version,pom.version
* POM files under src/etc/poms and subdirectories
if you've got mvn installed
$ mvn versions:set -DnewVersion=1.10.0 -DgenerateBackupPoms=false
inside src/etc/poms should do the trick.
* ivy.xml in release subdirectory (version should already be correct here)
* WHATSNEW (version should already be correct here)
* src/etc/testcases/taskdefs/conditions/antversion.xml (version should already be correct here)
6. Next bootstrap, build and run the tests.
$ ./bootstrap.sh
$ ./build.sh
$ ./build.sh test
# if you've got maven installed
$ mvn -f src/etc/poms/pom.xml -DskipTests package
7. Then build the distribution. It is important that this be a clean
build.
# clean
$ rm -rf bootstrap build dist distribution java-repository target
$ ./build.sh dist-lite
$ ./dist/bin/ant -nouserlib -lib lib/optional distribution
build.xml specifies that the code should be compiled with
source=1.8 and target=1.8.
8. Commit your changes, tag them, push them.
$ git tag -s -m "Tagging RC1 for version 1.10.0 of Ant" ANT_1.10.0_RC1
$ git push --tags
9. Ensure that the GPG key you use is inside the KEYS file in Ant's
git repository
<https://git-wip-us.apache.org/repos/asf?p=ant-antlibs-common.git;a=blob;f=KEYS;h=dc62b011b1b429bd6de913f8f2bce79b715f96db;hb=HEAD>
- and that you copy the KEYS file to /www/www.apache.org/dist/ant
Also make sure you have sent the key that you use to a public
keyserver.
10. Sign the distribution files
There are two aproaches, one uses Ant and a few libraries, the
other requires you to run gnupg manually. The first version didn't
work for Stefan when he built the first release candidate for
1.9.7.
a. Using the script release/signit.xml
This script requires using commons-openpgp to sign the artefacts,
This tool can be checked out from
http://svn.apache.org/repos/asf/commons/sandbox/openpgp/trunk
You have to build it using maven.
$ mvn install
The script assumes commons-openpgp (and bouncycastle) are in your
local maven repository.
You can create a property file gnupg.properties in your home directory
with your key id - like
keyid=5F6B8B72
or use -Dkeyid
and pass your key passphrase on the command line with -Dpassword=****
$ ./build.sh -f release/signit.xml -Dpassword=****
b. Using gpg
$ for i in distribution/*/*.zip distribution/*/*.gz distribution/*/*.bz2; do gpg --use-agent --detach-sign --armor $i; done
$ for i in java-repository/org/apache/ant/ant*/*/*.jar java-repository/org/apache/ant/ant*/*/*.pom; do gpg --use-agent --detach-sign --armor $i; done
11. Convert the part of the WHATSNEW file covering the changes
since the last release into HTML for the README file on the
website. See the previous release directories for examples of these files.
Use the target txt2html of docs.xml
$ ./build.sh -f docs.xml txt2html
This target generates a file build/html/WHATSNEW.html
Add an html head element with a title like "Release Notes of Apache Ant
1.10.0" (from the default txt2html)
Cut all sections about previous releases to keep only the current release,
and save as RELEASE-NOTES-1.10.0.html inside the distribution folder.
Copy the contents of RELEASE-NOTES-1.10.0.html also into README.html
12. The distribution is now ready to go.
Create a SVN sandbox on your computer with https://dist.apache.org/repos/dist/dev/ant in it
Copy the distribution folder to the location of the sandbox.
svn add the files and commit into https://dist.apache.org/repos/dist/dev/ant
13. Upload the maven artifacts located under java-repository/org/apache/ant
these artifacts comprise currently for each ant jar of one POM
file, the corresponding jar file and the corresponding GPG
signatures (x.pom, x.jar, x.pom.asc, x.jar.asc) MD5 and SHA1 are
generated by ivy during the upload
to
https://repository.apache.org (nexus repository)
using the build file release/upload.xml - this requires Ivy
$ ./build.sh -Dupload.user=foo -Dupload.password=secret -lib location_of_ivy_jar -f release/upload.xml
After the upload, you need to access the web interface of nexus
under https://repository.apache.org login using your Apache
credentials in the left pane, below "build promotion", click on
the "Stagings Repositories" links expand org.apache.ant select the
checkbox next to the upload that you just did click the button
"Close" on the top of the table listing the uploads make a note of
the location of the staging repository for the vote email
14. Once this is committed send a release vote email on dev@ant.
The email will typically mention :
- the git tag for the release including commit hash,
- the location of the tarballs, including revision number in
dist.apache.org repository
- the URL for the maven artifacts
The vote will only pass if at least three PMC members have voted +1
and more +1s than -1s have been cast. The vote will run for 3 days.
15. If the vote fails, address the problems and recreate the next RC
build.
16. Once the vote has passed, tag the last RC created with the final tag
$ git tag -s -m "Tagging version 1.10.0 of Ant" rel/1.10.0 HASH_OF_LAST_RC
$ git push --tags
17. The distrib artifacts should be published the apache dist. It is
managed via svnpubsub so the release should be committed to the
subversion repository
https://dist.apache.org/repos/dist/release/ant/.
* commit the new release files to
https://dist.apache.org/repos/dist/release/ant/[source|binaries|manual].
* Make https://dist.apache.org/repos/dist/release/ant/README.html
point to the new RELEASE-NOTES or a copy of it.
* release the maven artifacts using the web interface of nexus under https://repository.apache.org
login using your Apache credentials
in the left pane, below "build promotion", click on the "Stagings Repositories" links
expand org.apache.ant
select the checkbox next to the upload that you just did
and click the button "Release".
4 hours later, the artifacts will be in the maven central repository.
18. Update the Apache Reporter System
https://reporter.apache.org/addrelease.html?ant
19. Address the available version tags in BugZilla. Create new
milestone 1.10.1 and version 1.10.0.
20. Add a new release tag to doap_Ant.rdf in Ant's site.
21. checkout the master branch, merge the tag but don't push the
commit
[if a release of Ant 1.9.x happened at the same time, deal with
the 1.9.x tag on the 1.9.x branch first and merge the 1.9.x branch
to master before proceeding here]
$ git checkout master
$ git merge rel/1.10.0
Set the version number in several files to the required version of
the next 1.10.x release. These are:
* manual/cover.html
* manual/credits.html
* build.xml properties : project.version,manifest-version,pom.version
project.version property in build.xml gets bumped to
[newversion]alpha, for example 1.10.1alpha
manifest-version gets bumped to the exact next release number
for example 1.10.1.
pom.version gets bumped to [newversion]-SNAPSHOT
for example 1.10.1-SNAPSHOT.
* POM files under src/etc/poms and subdirectories
if you've got mvn installed
$ mvn versions:set -DnewVersion=1.10.1-SNAPSHOT -DgenerateBackupPoms=false
inside src/etc/poms should do the trick.
* ivy.xml in release subdirectory
* WHATSNEW (add a new section)
* src/etc/testcases/taskdefs/conditions/antversion.xml
Amend the merge commit
$ git add -u
$ git commit -a --amend
$ git push
22. wait a few hours for the mirrors to catch up
23. Update the ant.apache.org site :
The website is managed here: https://svn.apache.org/repos/asf/ant/site/ant/
Copy the manual of the release into the production folder - since
the site still uses svn and Ant proper uses git there currently is
no way to use the scm for this.
[TODO once there is the first release of 1.10.0, we'll likely need
to restructure the site to allow two versions of the manual to
exist in parallel]
Update the following files for version number:
* source/antnews.xml (Announcement)
* source/faq.xml (Ant's history details - not for betas)
* source/index.xml (Announcement, latest release details, link to
manual under "Documentation")
* source/srcdownload.xml
* source/bindownload.xml
* source/manualdownload.xml
Generate the html files by invoking 'ant'
Commit the modified/generated files in the 'production' folder, it will go
live on ant.apache.org in a matter on seconds.
24. At this point in time, the release is done and announcements are made.
PGP-sign your announcement posts.
Apache mailing lists that should get the announcements:
announce@apache.org, dev@ant and user@ant.
25. You can now reacquaint yourself with your family and friends.
26. After a few days "svn rm" the older release artifacts and release
notes from https://dist.apache.org/repos/dist/release/ant/
"older" here means any older 1.10.x release but not the latest
1.9.x release.

Files containing version information
------------------------------------
* manual/cover.html
* manual/credits.html

cover.html, credits.html, POM files, antversion.xml should be
adjusted for the [newversion] right after the build and tagging
of the release
build.xml
---------
right before a release :
the project.version gets bumped to the exact release
number, for instance 1.9.5
right after a release :
project.version property in build.xml gets bumped to
[newversion]alpha, for example 1.9.6alpha
