Oracle Wallet

I have finally been able to make liquibase aware of oracle wallet. I am running Oracle 11.2. The whole command is in one line,but I am showing it in multiple lines for clarity:

 mvn -X -e liquibase:update
-Dliquibase.emptyPassword=false (I have tried true no luck)
-Dliquibase.username=USER
-Dliquibase.url=jdbc:oracle:thin:/@oracle1
-Ddriver=oracle.jdbc.OracleDriver
-Doracle.net.tns_admin=/apps01/oracle/client/network/admin
-Doracle.net.wallet_location=/apps01/oracle/wallet
-Dliquibase.changelogSchemaName=USER
-Dliquibase.changelogCatalogName=USER
-Dliquibase.contexts=oracle1,my-ticket

Caused by: java.sql.SQLException: ORA-01005: null password given; logon denied

.I am passing all arguments in the command instead of using the liquibase.properties file.

Why is liquibase not picking up the password for USER ?
Yes the entries for tnsname.ora, sqlnet.ora, wallet.ora are all correct, since when I type “sqlplus /@oracle1” it works

$ sqlplus /@oracle1

Any clues? Pointers?

I have the same problem. Have you solved it?
