Determine Your Nexus Repository 3 Data Directory From Install Files
Go to the install directory of Nexus Repository created using the Nexus Installer program. It should contain a directory called ./bin/nexus.vmoptions. Inside the file, look for the line containing -Dkaraf.data=
. The value of this property is the Nexus Repository data directory.
If the value is a relative path, then it is relative to the install directory, not the ./bin directory containing the vmoptions file.
Determine Your Nexus Repository 3 Data Directory From Log Files
Use grep or another tool to look for log lines inside nexus.log files.
zgrep 'karaf.data' sonatype-work/nexus3/log/nexus*
The following sample log line reports where the data directory is located based on karaf.data property value:
2020-05-06 14:26:55,419-0300 INFO [FelixStartLevel] *SYSTEM org.sonatype.nexus.bootstrap.ConfigurationBuilder - karaf.data='/Users/example/app/nexus-installer-3.23.0-03-mac-archive/sonatype-work/nexus3'
Determine Your Nexus Repository 3 Data Directory From the Command Line
If Nexus Repository is running, you can print the command line that started Nexus Repository from your active process list to determine your data directory.

Look for the value of karaf.data. In the above example output we can see -Dkaraf.data=/app/nexus3/data so the location of the data directory is /app/nexus3/data.
