Prerequisites
Policy documents
The policy on releasing artifacts from an incubating Apache project is stated in the Guide to Release Management During Incubation. If any stated tasks in this document conflict with what is stated in the policy document, it must be brought to the notice of PPMC for further resolutionWhile Flume is now a top-level project, that guide is still a good resource for new release managers since it contains what are considered to be best practices.
The Release Manager (RM) must go through the policy document to understand all the tasks and responsibilities of running a release.

JIRA cleanup
1. Before a release is done, make sure that any issues that are fixed have their fix version fixVersion setup correctly. Run the following JIRA query to see which resolved issues do not have their fix version set up correctly:
...
JIRA: project
...
...
Flume and Resolution = Fixed and fixVersion is EMPTY
The result of the above query should be empty. If some issues do show up in this query that have been fixed since the last release, please bulk-edit them to set the fix version to '1.0.0'.
You can also run the following query to make sure that the issues fixed for the to-be-released version look accurate:
...
the version being released.
2. Since the JIRA release note tool will list all JIRAs associated with a particular fixVersion regardless of their Resolution, you may want to remove fixVersion on issues declared as "Duplicate", "Won't Fix", "Works As Expected", etc. You can use this query to find those issues, then just bulk edit them and leave the fixVersion field blank when editing them. (Note that you will need to replace "v1.4.0" below with the version you are trying to release.)
JIRA: project = Flume AND (Status != Resolved OR Resolution != Fixed) AND fixVersion = v1.6.0
3. Finally, check out the output of the JIRA release note tool to see which JIRAs are included in the release, in order to do a sanity check.
Monitor active issues
It is important that between the time that the umbrella issue is filed to the time when the release branch is created, no experimental or potentially destabilizing work is checked into the trunk. While it is acceptable to introduce major changes, they must be thoroughly reviewed and have good test coverage to ensure that the release branch does not start of being unstable.
...
Communicate with the community
1. Send an email to flume-dev@incubatordev@flume.apache.org to
Notify that you are about to branch.
Ask to hold off any commits until this is finished.
2. Send another email after branching is done.
...
Update the LICENSE file
The release manager is responsible for updating the LICENSE file to provide accurate license information for all binary artifacts contained in the codebase. This is a tedious and painstaking process, and must be performed for each release that includes a binary artifact.
Prepare branches and create tag
In this section, the release is X.Y.Z (e.g. 1.3.0)
1. Checkout the trunk.
Code Blocknoformat |
---|
svngit coclone httpshttp://svngit-wip-us.apache.org/repos/asf/incubator/flume/trunkflume.git flume |
2. Update CHANGES.txt CHANGELOG in the trunk .
For example,
Apache flume Change Log
No Format |
---|
Release 1.0.0
NEW FEATURES
FLUME-760 FLUME-728 Implement JDBC based channel implementation
...
|
to indicate the changes going into the new version.
The change list can be swiped from the JIRA release note tool (choose the "text" format for the change log). See JIRA Cleanup above to ensure that the release notes generated by this tool are what you are expecting. Additionally, in the last two releases we have re-ordered the issues to be New Features, Improvements, Bugs, etc as by default the least important items are at the top.
3. Update the "version" value in RELEASE-NOTES in trunk to X.(Y+1).0:
No Format |
---|
vim RELEASE-NOTES
git add RELEASE-NOTES
git commit RELEASE-NOTES -m "Updating Flume version in RELEASE-NOTES for release X.Y.Z" |
4. Create a branch for the X.(Y+1) release series
E.g. flume-1.5 should be branched off of trunk
No Format |
---|
git checkout trunk
git checkout -b flume-X.(Y+1)
|
43. Update the "version" value of all pom.xml and documentation files in trunk to "X.(Y+1).0.0".
4. Commit back to the trunk.
-SNAPSHOT
No Format |
---|
git checkout trunk
mvn versions:set -DnewVersion=X.Y.(Z+1)-SNAPSHOT -DgenerateBackupPoms=false

cd ..
git add .
git |
Code Block |
svn commit -m "PreparingUpdating trunk forversion release 1.0.0to X.$(Y+1).0-SNAPSHOT for Flume X.Y.Z release" |
5. Create a branch.
Code Block |

|
6. Update the "oldversion" value of all pom.xml in the trunk to "1.0.0".
7. Update the "version" value of all pom.xml in the trunk to "1.0.1-SNAPSHOT".
8. Commit back to the trunk.
Code Block |
---|
svn commit -m "Preparing for release 1.0.1 development"
|
9. Tag a candidate, where R (starting from 0) is the iteration number for this candidate:
Checkout the release branch and remove -SNAPSHOT from the release branch poms and docs and commit:
No Format |
---|
git checkout flume-X.Y
mvn versions:set -DnewVersion=X.Y.(Z+1)-SNAPSHOT -DgenerateBackupPoms=false
cd build-support
mvn versions:set -DnewVersion=X.Y.(Z+1)-SNAPSHOT -DgenerateBackupPoms=false
cd .. git add .
git commit -m "FLUME-XXXX: Removing -SNAPSHOT from X.Y branch" |
6. Ensure RELEASE-NOTES has the appropriate version and description of the release.
7. Push the branching changes upstream
No Format |
---|
git push -u origin trunk:trunk
git push -u origin flume-X.Y:flume-X.Y |
8. Tag a release candidate (in the example below, RC1):
No Format |
---|
git tag -a release-X.Y.Z-rc1 -m "Apache Flume X.Y.Z RC1"
git push origin release-X.Y.Z-rc1
|
If an rc2, rc3 etc is needed, simply create a new rc tag:
No Format |
---|
git tag -d release-X.Y.Z-rc2
git push origin release-X.Y.Z-rc2 |
Code Block |

---|
cd apache-flume-X.Y.Z-src
export LC_ALL=C.UTF-8 # Required to build the javadocs on some platforms and in some locales
mvn clean install -Psite -DskipTests
|
5. Verify that the HTML docs that should have been generated inside the binary artifact under /docs are there and do not have rendering errors.
Signatures and Checksums
All artifacts must be signed and checksummed. In order to sign a release you will need a PGP key. You should get your key signed by a few other people. You will also need to recv their keys from a public key server. See the Apache release signing page for more details.
1. Add your key to the KEYS file:
No Format |
---|
(gpg --list-sigs <your-email> && gpg --armor --export <your-email>) >> KEYS
|
And commit the changes.
2. Create and sign the artifacts, including site docs. This pushes the signed artifacts to the ASF staging repository.
In order to do this, you will need a settings.xml file with your username and password for the ASF staging repository. Typically this is placed in ~/.m2/settings.xml and might look something like this:
No Format |
---|
<settings>
<servers>
<server>
<id>apache.releases.https</id>
<username>your_user_id</username>
<password>your_password</password>
</server>
</servers>
</settings>
|
Once your settings.xml file is correct, you run the following from the flume root directory to generate and deploy the artifacts:
No Format |
---|
mvn clean deploy -Psite -Psign -DskipTests
|
This will sign, hash, and upload each artifact to Nexus.
Note: the checksum files will not be mirrored; They should be downloaded from the main apache dist site.
Do the same for javadoc and source artifacts:
No Format |
---|
mvn javadoc:jar gpg:sign deploy:deploy
mvn source:jar gpg:sign deploy:deploy
|
3. Publish Staging repository
Login to https://repository.apache.org and select Staging Repositories on the left under Build Promotion.
Select org.apache.flume from the list of repositories, verify it looks OK, and then click Close using "Apache Flume X.Y.Z" as the description to allow others to see the repository. Note that the staging repository will have a numeric id associated with it that will be used later
4. Copy artifacts to the distribution directories
Copy the apache-flume-X.Y.Z-{bin,src}.tar.gz{,.{asc,sha512}} files to the distribution directory.
Copy the distribution archive files from flume-ng-dist/target to where https://dist.apache.org/repos/dist/dev/flume is checked out on your machine.
- Use "svn delete" to remove any files from prior releases in the directory.
- Use "svn commit" to update the new files.
Update the staging website
- Clone https://github.com/apache/flume-site.
- Checkout the asf-staging branch.
- Add a page to the
source/sphinx/releases
directory for the new release, with the Changelog and links to the documentation (refer previous release pages for details. The documentation should simply use the same paths as the previous releases with correct versions - the documentation will be checked in directly to the production website as mentioned below).edit the new release page using a regex. The search string should be
Code Block ^(.*)\[FLUME\-(\d+)\](.*)$
and the replacement string should be
Code Block $1\[`FLUME-$2 <https://issues.apache.org/jira/browse/FLUME-$2>`__\]$3
- Update
content/sphinx/releases/index.rst
to update the pointer to the latest release. - Update
content/sphinx/download.rst
to also point to the latest release. - Update
content/sphinx/index.rst
as necessary to add a News item to the home page. - Copy the release version of the FlumeUserGuide.rst and FlumeDeveloperGuide.rst to the Documentation directory.
- Commit the changes and push them.
Run mvn package and verify the site at target/site/index.html.
- Run mvn pre-site install.
- Verify the site at https://flume.staged.apache.org.

Deploy Maven artifacts
General instructions on how to deploy the poms and jars to Maven Central can be found at the Apache page on publishing maven artifacts.
Flume-specific instructions:
After you get your settings.xml
file configured correctly (see above link) then you can run: mvn clean deploy -Psite -DskipTests -Papache-release
to push the artifacts to the staging repo.
You will need to go to the Apache Maven Repository @ http://repository.apache.org/ and log in with your Apache LDAP credentials
Once you log in you will see Build Promotion > Staging Repositories on the left hand side
You will want to edit the Flume artifacts that you don't want to push to Maven (you can delete stuff like the release tarball)
Click Close to make the atrifacts available on the Staging repository.
To push to Central, you click Release.
