Github user BrianOn99 commented on the issue: https://github.com/apache/incubator-predictionio/pull/401 I am using predicitonio 0.11 with postgres, and meet this issue `java.lang.ClassNotFoundException: jdbc.StorageClient` when using `pio-shell` when trying the tutorial https://predictionio.incubator.apache.org/datacollection/eventmodel/ As 0.12 is not released, I tried to apply this patch to 0.11 by appending `pio-data-jdbc-assembly-0.11.0-incubating.jar` to the `--jars` flag in `pio-shell` file, but then another error pops up ``` java.sql.SQLException: No suitable driver found for jdbc:postgresql://localhost/pio at java.sql.DriverManager.getConnection(DriverManager.java:689) at java.sql.DriverManager.getConnection(DriverManager.java:247) ``` Is it necessary to patch `Common.scala` and recompile? Or is there another way to do the same thing as `PEventStore.aggregateProperties` as shown in the tutorial without `pio-shell`? I really hope to have some help to be shown in the tutorial otherwise other newcomers like me will be confused.
