7

Although Empire-db is compatible with Java 6 we are ruilding Releases using JDK 7 in order to avoid certificate issues.

Java 8 or later have not been tested and approved.

The build process has been performed using Maven 3.3.9.

If Java 8 or later is installed on the machine, possibly create a mvn7

Currently we probably can only release using JDK 7 as there are certificate issues contacting the repository using JDK 6 (and JDK6 is not supported any more). So apply everything with jdk7 instead

Download the latest JDK 6 http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html

Create a mvn6 shell script and add it to your PATH . This script makes sure you use Java 6 in order to be able to use Java 7 to build the release.

Use /Library/Java/JavaVirtualMachines/xxx/Contents/Home as JAVA_HOME for mac/usr/bin/mvn6mvn7

#!/bin/sh
JAVA_HOME="/usr/lib/jvm/java-1.6.0-sun"
mvn $@

test the script by running this command:

>mvn6 --version
