Keep getting this error when I try to run jBilling version 4.1.1:

Error initializing the application: com/mchange/v2/c3p0/ComboPooledDataSource
java.lang.NoClassDefFoundError: com/mchange/v2/c3p0/ComboPooledDataSource

DB "jBilling-DataSource.groovy" file configure to work with MySQL:

dialect = "org.hibernate.dialect.MySQLDialect"
driverClassName = "com.mysql.cj.jdbc.Driver"
username = "root"
password = "root"
url = "jdbc:mysql:localhost:3306/jbilling"

When I run the "hsqldb" configuration, it works fine.

    Error is about the c3p0 dependency (compile 'com.mchange:c3p0:') but
    it should already be there except that it may not exist in the default war.
    You may have to rebuild the war.

    Hi Vikas,

      Can you tell me steps to rebuild the project? From what directory?

    Thanks for your help,
