Maven listLocks

Last updated: July 14, 2025

The Maven listLocks goal returns the hostname, IP address, and the timestamp the Liquibase lock record was added to the DATABASECHANGELOGLOCK table.

Uses

The Maven listLocks goal is typically used when an error occurs during a database deployment. The error might indicate that another user locked a record in the DATABASECHANGELOGLOCK table, preventing Liquibase from applying changes to the specified database.

The listLocks goal will read the DATABASECHANGELOGLOCK table and return a list that includes the hostname, IP address, and the timestamp the lock record was granted to the DATABASECHANGELOGLOCK table and determines the connections to the DATABASECHANGELOGLOCK table based on the database URL.

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.

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

Running the listLocks Maven goal

Running the listLocks goal requires a Maven project to be implemented. To run the goal, type the following in your command prompt:

mvn liquibase:listLocks

Maven listLocks

Maven listLocks output

When successful, the listLocks Maven goal produces the following output when there is no lock on the table:

[INFO] Executing on Database: jdbc:oracle:thin:@support.datical.net:1521:ORCL [INFO] SELECT MD5SUM FROM DATABASECHANGELOG WHERE MD5SUM IS NOT NULL AND ROWNUM=1 [INFO] SELECT COUNT(*) FROM DATABASECHANGELOGLOCK [INFO] SELECT COUNT(*) FROM DATABASECHANGELOGLOCK [INFO] SELECT ID,LOCKED,LOCKGRANTED,LOCKEDBY FROM DATABASECHANGELOGLOCK WHERE ID=1 FOR UPDATE Database change log locks for MVN_UAT@jdbc:oracle:thin:@support.datical.net:1521:ORCL - No locks

When there is a lock on the table, the listLocks Maven goal produces the following output:
