Current Release

This documentation covers the current version of Fedora. Looking for another version? See all documentation.

This document will walk you through getting the code, building the webapp, and exercising the REST API. 

Prerequisites

Fedora requires Java 8 and Maven 3 (only for building the project). Check that you have them installed before proceeding:

$ java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)
 
$ mvn -version
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T10:41:47-06:00)
Maven home: /Users/kford1/Programs/apache-maven-3.3.9
Java version: 1.8.0_73, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.13.6", arch: "x86_64", family: "mac"

Building Fedora

You can download pre-compiled binaries and run Fedora in an existing Tomcat or Jetty instance or pre-packaged Jetty instances, or build Fedora from source (it's not difficult or time consuming).

Clone the latest code from Github:

$ git clone https://github.com/fcrepo4/fcrepo4.git
Cloning into 'fc4'...
remote: Counting objects: 40152, done.
remote: Compressing objects: 100% (12759/12759), done.
Receiving objects:  14% (5622/40152), 3.68 MiB | 912 KiB/s  
[...]
 
$ cd fcrepo4

And build the project (the first time you build Fedora may take some time and bandwidth to download all the development dependencies):

$ MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m" mvn clean install

Running the Fedora webapp

The webapp can be run from a bundled instance of jetty. The application will listen on port 8080 by default.
If you would like to run the webapp on a different port, you can add the "jetty.port" option in your maven command (e.g. mvn -Djetty.port=8181 jetty:run)

$ cd fcrepo-webapp
$ MAVEN_OPTS="-Xmx512m" mvn jetty:run
