Liquibase at OpenShift

Hey guys!
I have a problem with liquibase maven plugin in OpenShift environment. The link to the database matches this pattern: jdbc:mysql://[username]:[password]@[host]:[port]/[schema].
I think you already know where the problem is…
Liquibase says that it can’t parse the number:
Cannot load connection class because of underlying exception: 'java.lang.NumberFormatException: For input string: "[password]@[host]:[port]"

Please, help me with this issue. Thank you in advance.
