Configuraciones para Maven para checkout condicional o actualización desde SVN?

Tengo las siguientes configuraciones en el file POM. Pero mi script de compilation falla con el post 'SVN file locked'. ¿Hay alguna otra manera de realizar el checkout condicional? Si el proyecto ya está desprotegido, entonces quiero actualizarlo solo; de lo contrario, si el proyecto no se revisa debería verificar el código y no debería actualizarlo. Gracias de antemano.

<!-- Initial check out of (will not do anything if directory already there) --> <execution> <id>check-out-project</id> <phase>generate-sources</phase> <goals> <goal>checkout</goal> </goals> <configuration> <checkoutDirectory>${project.build.directory}/project</checkoutDirectory> <connectionUrl>scm:svn:http://XX:XX/svn/repos/${XX}</connectionUrl> <username>${svn.username}</username> <password>${svn.password}</password> <skipCheckoutIfExists>true</skipCheckoutIfExists> </configuration> </execution> <!-- Update project (if directory was already there) --> <execution> <id>update-project</id> <phase>generate-sources</phase> <goals> <goal>update</goal> </goals> <configuration> <basedir>${project.build.directory}/project</basedir> <connectionUrl>scm:svn:http://XXX:XXX/svn/repos/${project}</connectionUrl> <username>${svn.username}</username> <password>${svn.password}</password> <revisionKey>project.revision</revisionKey> </configuration> </execution> 

Registro de errores después de ejecutar maven (tenga en count que he reemplazado routes de directory y URL con xxxx)
