Answer already given in comments by @rseddon . Adding it here so that the answer can be accepted.

java.net.BindException means that the process cannot listen on the given port as the port is already occupied (usually by an existing process). In the case of nexus start up, it indicates that some other process is listening on this port.

You can either find that process and kill it. On MS Windows, this could be found out by running netstat and tasklist as follows (assuming port 8081 is where its trying to bind and the first command gives pid 2216):

netstat -ano | findStr "8081"
tasklist /fi "pid eq 2216"

Or you could change the port nexus is trying to listen on , which is specified in the file <installDir>\\sonatype-work\\nexus3\\nexus.properties .
