Neo4j batch insert - version mismatch?

I'm attempting to insert data into Neo4J using the Java APIs described here: http://neo4j.com/docs/stable/batchinsert-examples.html . I downloaded neo4j-community-2.1.6-unix.tar.gz and unpacked it, then created a BatchInserters.inserter("/path/to/neo4j/data/graph.db") and began the import process.

My Java project uses the following Maven dependency to get Neo4j:

<dependency>
    <groupId>org.neo4j</groupId>
    <artifactId>neo4j</artifactId>
    <version>2.2.0-M01</version>
</dependency>

If I run the import and data already exists at data/graph.db (even by doing just a bin/neo4j start; bin/neo4j stop), then I get this error:

org.neo4j.kernel.impl.store.NotCurrentStoreVersionException:
  Was expecting store version [v0.A.4] but found [StringPropertyStore v0.A.3].
  Store cannot be upgraded automatically.

    at org.neo4j.unsafe.batchinsert.BatchInserters.inserter(BatchInserters.java:51)

If I instead leave the data/graph.db directory uncreated and perform the import, the import seems to go as planned, but I can't start up the database afterward - here's what's in the log after an unsuccessful bin/neo4j start:

% cat data/log/console.log
2014-12-11 21:52:22.942+0000 INFO  [API] Setting startup timeout to: 120000ms based on -1
Detected incorrectly shut down database, performing recovery..

No actual recovery seems to be performed though, as far as I can tell.

If I need an older version of the importer codebase or something, where could I find that?

Figured it out - it was as easy as changing my Maven dependency to <version>2.1.6</version>. Duh.
