GeoMesa Development

This chapter describes how to build GeoMesa from source and provides an overview of the process of developing GeoMesa.

Using Maven

The GeoMesa project uses Apache Maven as a build tool. The Maven project’s Maven in 5 Minutes provides a quick introduction to getting started with its mvn executable.

Building from Source

These development tools are required:

The GeoMesa source distribution may be cloned from GitHub:

$ git clone
$ cd geomesa

This downloads the latest development version. To check out the code for the latest stable release ($VERSION = 2.0.2):

$ git checkout tags/geomesa-$VERSION -b geomesa-$VERSION

Building and dependency management for GeoMesa is handled by Maven. The Maven pom.xml file in the root directory of the source distribution contains a list of dependent libraries that will be bundled together for each module of the program. Build using the mvn executable:

$ mvn clean install

The skipTests property may be used to reduce build time, as it omits the test phase of the build process:

$ mvn clean install -DskipTests

To compile for Google Bigtable, use the bigtable profile:

$ mvn clean install -Pbigtable

The build/mvn script is a wrapper around Maven that builds the project using the Zinc incremental compiler:

$ build/mvn clean install -DskipTests


For the most part, GeoMesa is written in Scala, and is compiled with Scala 2.11.7.

Using the Scala Console

To test and interact with core functionality, the Scala console can be invoked in a couple of ways. For example, by running this command in the root source directory:

$ mvn scala:console -pl geomesa-accumulo/geomesa-accumulo-datastore

The Scala console will start, and all of the project packages in geomesa-accumulo-datastore will be loaded along with JavaConversions and JavaConverters.
