Releasing Akka requires running on JDK 11, but also having JDK 8 installed. The reason for this is that we want the Akka artifacts to be usable with JRE 8, but also want to compile some classes with JDK11-specific types.
In the future we might be able to update the build to work
without having JDK 8 installed, by using the -release
option.
If you have not set up GPG or used sbt-pgp
on the release machine
- Check the sbt-pgp usage for any setup steps you may still need, for example:
sbt> set pgpReadOnly := false
sbt> pgp-cmd gen-key
- Check that signing works with
sbt> publishLocalSigned
When releasing from MacOS you may want to use YubiKey or have MacGPG installed.
When releasing from Windows, you need MinGW and a gpg distribution such as Gpg4Win
Make sure you have set core.autocrlf
to false
in your ~/.gitconfig
,
otherwise git might convert line endings in some cases.
Make sure you have the Lightbend Whitesource credentials configured in
your ~/.sbt/1.0/private-credentials.sbt
.
Graphvis is needed for the scaladoc generation build task, which is part of the release.
Make sure you have completed the setup in project/scripts/release
.
Nightly snapshot releases are created from master and published to https://repo.akka.io/snapshots by https://jenkins.akka.io:8498/job/akka-publish-nightly/
To create snapshot versions manually, use sbt clean stampVersion publish
.
The release artifacts are created in akka-*/target/repository
and can be
copied over to a maven server. If you have access, the Jenkins job at
https://jenkins.akka.io:8498/job/akka-publish-wip/ can be used to publish
a snapshot to https://repo.akka.io/snapshots from any branch.
- Do a
project/scripts/release <version>
dry run - If all goes well,
project/scripts/release --real-run <version>
- Log into sonatype, 'close' the staging repo.
- Test the artifacts by adding
resolvers += "Staging Repo" at "https://oss.sonatype.org/content/repositories/comtypesafe-xxxx"
to a test project - If all is well, 'release' the staging repo.
-
Prepare milestone on github:
-
go to the Milestones tab
-
move all open issues so that this milestone contains completed work only
-
close that milestone
-
create a new milestone for next patch version
-
In case of a new minor release:
-
update the branch descriptions at CONTRIBUTING.md#branches-summary
-
write blog post for akka.io and lightbend.com
-
Create an announcement as a PR against akka/akka.github.com .
- credits can be generated with
scripts/authors.scala v2.3.5 v2.3.6
- also update the
latest
variable in_config.yml
.
- credits can be generated with
Now wait until all artifacts have been properly propagated. Then:
-
Update
MiMa.latestPatchOf
and PR that change (project/MiMa.scala
) -
Change the symbolic links from 'current':
ssh [email protected] ./update-akka-current-version.sh <x.y.z>
-
Publish the release announcement
-
Tweet about it
-
Post about it on Discuss
-
Post about it on Gitter
