PHP Fatal error: Call to undefined method Doctrine_Connection_Oracle::getDeclaration() in ....\Doctrine\Export\Oracle.php on line 501

When I try to execute a migration of my DB with doctrine CLI migrate, i get this error.
I fixed it changing the following in Export/Oracle.php
#501 : $fields[] = $this->conn->getDeclaration($fieldName, $field); => $fields[] = $this->getDeclaration($fieldName, $field);

#509 : $fields[] = $fieldName. ' ' . $this->conn->getDeclaration('', $field['definition']); => $fields[] = $fieldName. ' ' . $this->getDeclaration('', $field['definition']);
