generate-changeset-created-values

The generate-changeset-created-values global parameter is a Boolean that determines whether Liquibase adds timestamps to changesets in the changelog it generates when you run the diff-changelog command and generate-changelog command. By default, it is set to false.

Uses

If you use the diff-changelog or generate-changelog commands to create a changelog with the contents of your database, you can set generate-changeset-created-values to true to include a timestamp in the header of each changeset in your changelog. The timestamp is stored as the value of the created parameter and uses the format YYYY-MM-DD hh:mm-ssss.

Syntax

You can set this parameter in the following ways:

Option Syntax
Liquibase properties file 
liquibase.generateChangesetCreatedValues: <true|false>
Global CLI parameter 
liquibase
 --generate-changeset-created-values=<true|false> generate-changelog
 --changelog-file=example-changelog.xml

JVM system property (JAVA_OPTS Environment Variable)

 
JAVA_OPTS=-Dliquibase.generateChangesetCreatedValues=<true|false>
Liquibase Environment Variables 
LIQUIBASE_GENERATE_CHANGESET_CREATED_VALUES=<true|false>

For more information, see Working with Command Parameters.

Output

If you run a command like generate-changelog with generate-changeset-created-values set to true, the output is:

BEST PRACTICE: The changelog generated by diff-changelog/generate-changelog should be inspected for correctness and completeness before being deployed.
Generated changelog written to C:\<filepath>\dbchangelog.xml
Liquibase command 'generate-changelog' was executed successfully.

The generated changelog includes a created parameter that has a timestamp:
