Download the latest snapshot from nexus using wget

From Maven 3, support for uniqueVersion is disabled and when you distribute your snapshots by publishing them on nexus you end up with snapshot names ending with timestamps. Suddenly your QA or Integration server scripts start failing if you are getting war file from nexus repository as there is no unique name now.

To get the latest version of snapshot you can use a service available from Nexus as

wget -O my-services.war http://nexus.myorg.net/nexus/service/local/artifact/maven/redirect?r=snapshots\&g=my.company.product.services\&a=my-services\&v=1.0-SNAPSHOT\&p=war

Where
r is the id of the repository
g is the group id
a is the artifact id
v is the version of artifact
p is the packaging type

The argument -O helps in renaming the output file to the name you want so that you have a fixed name you can use in your shell script.
