Technical goals:

• More flexible storage options
• Improved reporting and metrics
• Improved durability

System Requirements

• Java 8
• Maven 3

$ git clone https://github.com/fcrepo4/fcrepo4.git
$ cd fcrepo4
$ MAVEN_OPTS="-Xmx1024m" mvn install
$ cd fcrepo-webapp
$ MAVEN_OPTS="-Xmx512m" mvn jetty:run

Note: You may need to set the $JAVA_HOME property, since Maven uses it to find the Java runtime to use, overriding your PATH. mvn --version will show which version of Java is being used by Maven, e.g.:

Java version: 1.8.0_31, vendor: Oracle Corporation
Java home: /usr/local/java-1.8.0_31/jre

To set your $JAVA_HOME environment variable:

JAVA_HOME=/path/to/java

If you have problems building fcrepo4 with the above settings, you may need to also pass options to the JaCoCo code coverage plugin:

$ MAVEN_OPTS="-Xmx1024m" mvn -Djacoco.agent.it.arg="-Xmx1024m" -Djacoco.agent.ut.arg="-Xmx1024m"  clean install
