Though I can execute the dataloader from the command-line with the default settings, and it will work fine as long as my config.properties file is set up, I'm not able to configure it with command-line arguments.

The following command is giving me a login error. But I know for sure my credentials are good. This same operation works successfully when I have the same username,password,and endpoint populated in the config.properties file. Please demonstrate the correct formatting.

C:\temp\sfdataloader>java -jar sforcedataloader.jar -username hxqv_me@mydomain.com_test -password mypassword -operation extract -extractionSOQL "SELECT ID,Name from Account" -endpoint https://test.salesforce.com -extractionTarget account.csv -entity Account
