Download maven from http://maven.apache.org/download.cgi. At this point for writing, I downloaded Maven 3.2.1 tar.gz file.

Extract the package file. Personally I like to store all my applications in /Applications. So I have extracted to:

/Applications/apache-maven-3.2.1

Add maven to Environment Variable:

Open/create bash_profile:

vim ~/.bash_profile

Add the following lines:

export M2_HOME=/Applications/apache-maven-3.2.1 export PATH=$PATH:$M2_HOME/bin

Reload the changes:

source ~/.bash_profile

Test if maven is installed correctly. In terminal type this:

mvn -version

You should see the following:

Download java. At this point of writing, I downloaded java 1.7 from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

Add JAVA_HOME environment variable:

Open/create:

vim ~/.bash_profile

Add this line:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre

Reload the changes:

Prerequisite:

Setup Default Gateway correctly. Please see here, Step 4

Setup a DNS server. Please see here

Register a DDNS service. Follow the instruction here. In this example, I picked dyndns and registered a dyndns-ip.com hostname because I faced some problems in using dyndns-office.com. Note: you can use hostname other than dyndns. E.g: no-ip, update.ods.org, dhs.org, dyns,cx, 3322.org. But their configuration maybe different. I am not sure.

Login to Qnap web interface, go to Control Panel > System Settings > Network > DDNS Service

Key in your dyndns username, password, hostname(From Step 1 when you sign up for a hostname) . If you have done step 1 and step 2 correctly, under Current WAN IP you should see your WAN IP, and NOT LAN IP. Earlier on when my DNS and Default Gateway settings were incorrect, it was showing my LAN IP (ie: 192.168.1.1). Your WAN IP is your public IP. Go here to get your public IP

Click apply and everything should work correctly. You should not see any error.

FAQ on What should I do when the error message ''System has detected that your DNS server can't resolve hosts…” is shown?: http://www.qnap.com/useng/?lang=en-us&sn=892&c=1106&sc=2166&n=9506

Login to QNAP web interface

Go to Control Panel > System Settings > Network > TCP/IP tab

Under DNS Server, key in the primary and secondary DNS server. These IP addresses can be gotten from your router WAN settings.

If you're unsure of this DNS server, you can use Google free DNS server. They are:

Primary server: 8.8.8.8

Secondary server: 8.8.4.4

You can read more on Google DNS @ Google Public DNS

Click Apply. That's it

If you receives error such as this:

System has detected that your DNS server can't resolve hosts…

Login to your QNAP web interface

Go to Control Panel > System Settings > Network

Under TCP / IP tab, click edit / add IP address

Figure 1. Under Network Parameters tab, select Use Static IP address. Key in your Fixed IP Address, Subnet Mask and most importantly Default Gateway. Why is it important? This will affect your DNS service, DDNS service and other applications

How to get your Default Gateway? On a mac or linux machine, open terminal and type this:

netstat -nr

You should see your default IP address. In my case, the default IP address is my router IP.
