Shapeshifter uses Maven as a build system. More information on how to get and use Maven may be found at maven.apache.org/.
Apart from the standard dependencies declared in the pom.xml file, this library requires the Protocol Buffer compiler, a.k.a protoc, to be present on the host. protoc is an executable program distributed as part of the open-source Protocol Buffers project. You may install the compiler by downloading its source from the official repository and following the instructions for building it.
Shapeshifter's Maven artifact relies on Sergei Ivanov's Maven plugin for invoking the protocol buffer compiler. This plugin uses Maven's toolchain mechanism to find the path to the compiler. See the plugin's manual to find a sample configuration.
Once you have installed protoc and declared the proper toolchain, you may build this library by running:
$ mvn compile
You may package this library by invoking:
$ mvn package
