Repository Management with Nexus
3.1. Nexus Prerequisites

Nexus Open Source and Nexus Professional only have one prerequisite, a Java Runtime Environment (JRE) compatible with Java 6 or Java 7. Nexus is most often run with the JRE that is bundled with a Java Development Kit (JDK) installation, and it can be run with Oracle’s JDK for Java 6 or Java 7. To download the latest release of the Oracle JDK, go to http://www.oracle.com/technetwork/java/javase/downloads/index.html , and download the latest Java 6 or Java 7 JDK.

At a minium Java 6 Update 30 or Java 7u2 are required. IBM Java versions 6 and 7 are supported as well. In all instances we recommend tha latest available version.

When encountering problems related to IPv6 usage with Nexus or Maven as is the default with Java 7, a known workaround is to configure

java.net.preferIPv4Stack=true
