Building Neo4j from GitHub source

[bi...@bunkat.com]

What is the right way to go from the source that is available on GitHub to an actual working Neo4j server? There are fixes that went in yesterday that I would really like to test and they don't appear to be in the SNAPSHOT build that is available at http://www.neo4j.org/download.  

Based on the readme provided and tips I've gotten from Wes in another thread, this is what I've tried so far:

1. git clone https://github.com/neo4j/neo4j.git
2. cd neo4j
3. mvn clean install

Result: Build fails in HA tests

1. git clone https://github.com/neo4j/neo4j.git
2. cd neo4j/community
3. mvn clean package

Result: Build is successful, bunch of jar files built in various directories

1. Download neo4j 2.0.0 M5 build
2. Copy cypher, graph-algo, graph-matching, jmx, kernel, lucene-index, shell, udc jar files into the 2.0.0-M5/lib folder using the M5 jar names
3. Try to start server using ./neo4j start

Result: Server fails to start

1. Copy server, server-static-web jar files into the 2.0.0-M5/system/lib folder using the M5 jar names
2. Try to start server using ./neo4j start

Result: Server fails to start

Any help would be appreciated.  Thanks!

Do you get any errors in the logs that might indicate why it's failing to start? My strategy might work better with the snapshot release in case there's a gap somewhere else.

#2 sounds easier to fix. Are you loading it with a config file? It seems to be missing the keep_logical_logs setting...

[bi...@bunkat.com]

Everything is default.  Looks like there is a keep_logical_logs setting in neo4j.properties.  I tried to comment it out but the server fails to start with the same error.

Try building packaging :

cd packaging/standalone
mvn clean install

The different versions should be in target /

Can you please tell me where can the SNAPSHOT builds be found. On the download I can only see 2.0.0 or previous versions.

Thanks,
