Subject Re: Schema generation with Ant

Hi Joerg,

The PostgresAdapter is definitely part of the snapshot:

$ jar tvf ~/.m2/repository/org/apache/cayenne/cayenne-server/3.1M4-SNAPSHOT/cayenne-server-3.1M4-SNAPSHOT.jar
| grep PostgresAdapter
  8090 Fri Feb 24 09:01:24 EST 2012
org/apache/cayenne/dba/postgres/PostgresAdapter.class

The only thing I'm noticing offhand is the documentation lists the
Cayenne jars as:

   <fileset dir="lib" >
      <include name="cayenne-tools-X.X.jar" />
      <include name="cayenne-server-X.X.jar" />
      <include name="third-party/vpp-2.2.1.jar" />
   </fileset>

And you have a leading "cayenne/" in front of yours:

            <fileset dir="lib">
                   <include name="cayenne/cayenne-tools-3.1M4-SNAPSHOT.jar" />
                   <include name="cayenne/cayenne-server-3.1M4-SNAPSHOT.jar" />
                   <include name="cayenne/third-party/vpp-2.2.1.jar" />
                   <include
name="cayenne/third-party/commons-collections-3.1.jar" />
                   <include
name="cayenne/third-party/commons-logging-1.1.jar" />
                   <include name="cayenne/third-party/velocity-1.6.3.jar" />
            </fileset>
