That would make sense to me as well. But like I said, on the first
run, the method is found. Running the exact same code a second time,
without any changes, it complains that the method is not found. (?!)
Here the versions I use (for both runs) from my pom.xml:
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-kernel</artifactId>
<version>1.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.neo4j</groupId>
<artifactId>neo4j-index</artifactId>
<version>1.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-highlighter</artifactId>
<version>2.9.1</version>
</dependency>
Cheers,
Max
