Maven clearCheckSums

Last updated: August 21, 2026

The clearCheckSums goal clears all checksums and nullifies the MD5SUM column of the DATABASECHANGELOG table. They will be re-computed on the next database update --changesets that have been deployed will have their checksums re-computed, and pending changesets will be deployed.

Uses

The clearCheckSums goal is typically used when there is an MD5Sum Check Failed error message and there is a need to clear the checksums from the DATABASECHANGELOG table.

Maven configuration

You can configure Liquibase Maven in multiple ways. You can pass arguments like <changeLogFile> in Maven directly in your pom.xml file, in a liquibase.properties file referenced in your POM, as environment variables, or as JVM system properties. To learn about each file's syntax, see Maven Properties.

For more information about the Maven configuration, see Configuring Maven.
