Hi,

I am evaluating liquibase to diff two databases. The goal is to have one master database and find missing or changed columns in the target database. Ideally the plan is, to emit SQL code to bring the target up to date. Both databases run on the same database system which is Sybase ASE 15. I changed the column length of a varchar column (enlarged) and created a new table in the master database. Then I ran liquibase with either jconn3.jar from Sybase itself and as this showed no differences I changed the JDBC driver to be jTDS. Either way no differences were detected and reported. The following output is generated:

0 [hostA]/liquibase|> ./liquibase --driver=net.sourceforge.jtds.jdbc.Driver --url=jdbc:jtds:sybase://hostA:8300/target --username=user --password=password diff --referenceUrl=jdbc:sybase:Tds:hostB:8305/master --referenceUsername=user --referencePassword=password
Liquibase Home is not set.

Did I forget any essential flag to get it working? Any help welcome.
