• Perform an git clone and switch to the correct branch
  • git clone https://github.com/apache/tomcat /c/releases/asf-tomcat or git clone -b 9.0.x git clone https://github.com/apache/tomcat /c/releases/asf-tomcat
  • cd /c/releases/asf-tomcat
  • git checkout 9.0.x
  • git pull
• (Hint: using ant pre-release  may save you the following step, plus steps 2-3 in the Maven release process.)

• Edit "build.properties.default" and change the lines after "# ----- Reproducible builds -----" to a new value. (NOTE: this is done by 'ant pre-release')

  • Note that the value of ant.tstamp.now property is in seconds (unlike the value returned by System.currentTimeMillis() method which is milliseconds, see bug 65527 for how this happened for Tomcat 8.5.70).
    The value can be printed in a Bash shell with the following command:
    date +%s
    To print seconds since epoch, and date and time in human-readable format in UTC time zone:
    date -u '+%s %Y-%m-%d %H:%M:%S %Z'

• Edit "build.properties.default" and change the line version.dev=-dev to version.dev= (NOTE: this is done by 'ant pre-release')

  • This can be done with sed -i.bak "s/^version.dev=.*/version.dev=/" build.properties.default
• Edit "webapps/docs/changelog.xml" and replace rtext="in development" with rtext="Release in progress" for the version being released (NOTE: this is done by 'ant pre-release')
  
  • Remember that notepad.exe will remove UTF-8 Byte-Order Marks (BOMs). Use write.exe or Notepad++ instead.
• Build the release

  • ant release

• Commit these changes

  • git add --all (to pick-up the repeatable build artifacts in addition to the content-changes from above ; is this necessary with commit --all?)

  • git commit --all --message "Tag 9.0.94"
  • git tag 9.0.94
  • git push origin 9.0.94
• Check the diff mailed to the dev list

...

• Reset to the 9.0.x branch (git reset HEAD~ && git checkout build.properties.default && git checkout webapps/docs/changelog.xml && rm -f build.properties.release res/maven/mvn.properties.release res/install-win/Uninstall.exe.sig res/install-win/tomcat-installer.exe.sig)

I found it simplest to keep this clone for tagging to ensure no other edits found their way into the tag.
