- Clone the Titan repository from GitHub to a local directory.
- In that directory, execute
mvn clean install. This will build Titan and run the internal test suite. The internal test suite has no external dependencies. Note, that running all test cases requires a significant amount of time. To skip the tests when building Titan, execute
mvn clean install -DskipTests
- For comprehensive test coverage, execute
mvn clean test -P comprehensive. This will run additional test covering communication to external storage backends, performance tests and concurrency tests. The comprehensive test suite uses Cassandra and HBase as external databases and requires that Cassandra and HBase are installed. Note, that running the comprehensive test suite requires a significant amount of of time (> 1 hour).
For developing against the most current version of Titan, depend on Titan snapshot releases. Note, that these releases are development releases and therefore unstable and likely to change. Unless one is interested in the most recent development status of Titan, we recommend to use the stable Titan release instead.
<dependency> <groupId>com.thinkaurelius.titan</groupId> <artifactId>titan-core</artifactId> <version>X.Y.Z-SNAPSHOT</version> </dependency>
When adding this dependency, be sure to add the following repository to the
<repository> <id>sonatype-nexus-snapshots</id> <name>Sonatype Nexus Snapshots</name> <url>https://oss.sonatype.org/content/repositories/snapshots</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository>
Maven build causes dozens of "[WARNING] We have a duplicate…" errors
Make sure to use the maven-assembly-plugin when building or depending on Titan. Please refer to Issue #84 for more information.
