I have Linux OS and I do not have access to REST API, so I used following commands to get the latest version of snapshots from Nexus:

An example snapshots maven-metadata.xml from WSO2 repository:

$ curl -s "http://maven.wso2.org/nexus/content/repositories/snapshots/org/wso2/is/wso2is/maven-metadata.xml"


  org.wso2.is
  wso2is
  
    5.3.0-SNAPSHOT
    
    
      5.1.0-SNAPSHOT
      5.2.0-SNAPSHOT
      5.3.0-SNAPSHOT
    
    20160914062755
  

Extracting from latest XML tag inside maven-metadata.xml:

curl -s "http://maven.wso2.org/nexus/content/repositories/snapshots/org/wso2/is/wso2is/maven-metadata.xml" | \
grep ".*" | \
sed -e "s#\(.*\)\(\)\(.*\)\(\)\(.*\)#\3#g"

Extracting from version XML tag inside maven-metadata.xml:

curl -s "http://maven.wso2.org/nexus/content/repositories/snapshots/org/wso2/is/wso2is/maven-metadata.xml" | \
grep ".*" | \
sort --version-sort | uniq | tail -n1 | \
sed -e "s#\(.*\)\(\)\(.*\)\(\)\(.*\)#\3#g"

The result of both of the commands until today 14 Sep 2016 is:

5.3.0-SNAPSHOT
