*Last updated: July 24, 2025*

CRQLabelRequired is a custom policy check that tells Liquibase all changesets must have a CRQ (change request) label assigned.

regex: (?i:crq\d+)

Note: These steps describe how to create the custom policy check. It does not exist by default in Liquibase Pro.

Before you begin

  • Liquibase 4.29.0+

  • Python 3.10.14+

  • Configure a valid Liquibase Pro license key

  • Create a Check Settings file

  • Ensure the Liquibase Checks extension is installed. In Liquibase 4.31.0+, it is already installed in the /liquibase/internal/lib directory, so no action is needed.

  • If the checks JAR is not installed, download liquibase-checks-<version>.jar and put it in the liquibase/lib directory.

    • Maven users only:

      Add this dependency to your pom.xml

      file: <dependency> <groupId>org.liquibase.ext</groupId> <artifactId>liquibase-checks</artifactId> <version>2.0.0</version> </dependency>

  • Java Development Kit 17+ (available for Open JDK and Oracle JDK)

  • Linux, macOS, or Windows operating system

Procedure

These steps describe how to create the Custom Policy Check. It does not exist by default in Liquibase Pro.

1

Provide Liquibase with a label value by entering this into the CLI:

liquibase checks copy --check-name=UserDefinedLabelCheck
2

Give your check a short name for easy identification

Use up to 64 alpha-numeric characters only.

In this example we will use:
ContextEnvironmentsDevUatProd
3

Set the Severity to return a code of 0-4 when triggered.

These severity codes allow you to determine if the job moves forward or stops when this check triggers. Learn more here: Use Policy Checks in Automation: Severity and Exit Code options: 'INFO'=0, 'MINOR'=1, 'MAJOR'=2, 'CRITICAL'=3, 'BLOCKER'=4

4

Set the OPERATOR to the REGEXP option.

These are the options for this step: STARTS_WITH, ENDS_WITH, CONTAINS, REGEXP, EQUALS) [STARTS_WITH].

In this example, since we are creating a regex check, we will set the operator to REGEXP.

5

Set the SEARCH_STRING (options: a string, or a valid regular expression)
