git clone -b BLAZEGRAPH_RELEASE_2_1_4 --single-branch BLAZEGRAPH_RELEASE_2_1_4

Maven Central

Blazegraph 2.1.4 is now on Maven Central.    You can also get the Tinkerpop3 API and the new BlazegraphTPFServer.

    <!-- Use if Tinkerpop 2.5 support is needed ; See also Tinkerpop3 below. -->


Blazegraph Tinkerpop3

Tinkerpop3 is here!  Get it from Maven Central.



Everybody loves (and hates) Maven.  Starting with the 2.0.0 release, Blazegraph has been broken into a collection of maven artifacts.    This has enabled us to work on new features like TinkerPop3, which require Java 8 support while keeping the core platform at Java 7 to support users who are still there.   Checkout the Maven Notes on the wiki for full details on the architecture, getting started with development, building snapshots, etc.  If you have a 1.5.3 version checked out in Eclipse, you will want to pay attention to Getting Started with Eclipse and allocate a little extra time for the transition.


2.1.4 provides updates for the Debian Deployer, an RPM Deployer, and a Tarball.  In addition to the blazegraph.war and blazegraph.jar archives.

    It seems that the BlazegraphTPFServer (link under “Maven Central”) is not available anymore, or located elsewhere: clicking on the link returns a 404 not found

  2. Eric Stephan

    GIven that the last release was two years ago is it safe to say the Open Source Blazegraph development has stopped?

    @Eric, this was my question as well — is anyone actively doing any development — where have all the developers gone?
