schemacrawlar can't print out table name - schemacrawler

Question

blow code just print out database name only,why?
public static void main(final String[] args) throws Exception
{
// Create a database connection
final DataSource dataSource = new DatabaseConnectionOptions("jdbc:mysql://localhost:3306/target_db");
final Connection connection = dataSource.getConnection("root", "password");
// Create the options
final SchemaCrawlerOptions options = new SchemaCrawlerOptions();
options.setSchemaInfoLevel(SchemaInfoLevelBuilder.standard());
options.setTableTypes(Lists.newArrayList("BASE TABLE","TABLE","VIEW"));
options.setRoutineInclusionRule(new ExcludeAll());
options.setSchemaInclusionRule(new RegularExpressionInclusionRule("target_db"));
options.setTableNamePattern("*");
// Get the schema definition
final Catalog catalog = SchemaCrawlerUtility.getCatalog(connection, options);
for (final Schema schema : catalog.getSchemas())
{
System.out.print("c--> " + schema.getCatalogName() + "\n");
for (final Table table : catalog.getTables(schema))
{
System.out.print("o--> " + table);
if (table instanceof View)
{
System.out.println(" (VIEW)");
} else
{
System.out.println();
}
for (final Column column : table.getColumns())
{
System.out.println(" o--> " + column + " (" + column.getColumnDataType() + ")");
}
}
}
}
}
Strangely,
./schemacrawler.sh -server=mysql -database=target_db -user=root -password=password -infolevel=ALL -command=schema
will output tables and corresponded columns.
Update:my configuration
schemacrawler-14.09.03-main
Ubuntu 16.04 64bit
MariaDB 10.2.1-MariaDB-1~xenial
(I assumed mariadb may not be supported yet,so switch between blow two drivers,but neither works)
mysql-connector-java-6.0.3
mariadb-java-client-1.4.6

Answer 1

Finally,I figured it out:
options.setTableTypes(Lists.newArrayList("BASE TABLE","TABLE","VIEW","UNKNOWN"));
Caution:with MariaDB,table types is "UNKNOWN"
