Subject Ant , maven , antrun , ddlutils
Date Wed, 24 Feb 2010 21:59:01 GMT

Hello everyone

First impressions of the post might be that its not an ant related issue but
I am not sure so please bear with me and read along. I am trying to use
ddlutils with maven. No ready ddlutils plugin available for maven. So I am
working with ant-run plugin. When I run the maven pom file, I get the
following output. You can notice here that the echo statement echoes the
driver value from the properties file first time and then after that it does
not. I am not sure why this is happening. Could somebody throw somelight on
this.

Thanks
Venkat

My config:

<property file="./resources/ddlutils/Database.properties" prefix="db" />
				<echo>${db.driver}</echo>
				<taskdef classname="org.apache.ddlutils.task.DatabaseToDdlTask"
name="databaseToDdl"
					classpathref="maven.compile.classpath" />
				<databaseToDdl usedelimitedsqlidentifiers="true" modelname="lean"
verbosity="DEBUG">					
					<database driverclassname="org.postgresql.Driver" url="${db.url}"
username="${db.username}" password="${db.password}" />				
					<writeschematofile outputfile="./resources/database/schema-lean.xml" /> 
				</databaseToDdl>
