I am using Nexus Repository 3 as storage for my build files. More precisely WAR and JAR artefacts which are deployed to repository via Maven deploy plugin.
I have been searching in multiple folders under /sonatype-work/nexus3/ but I couldn't find any files.
Where exactly (file path) is Nexus storing WAR and JAR files?
In Nexus Repository 3 the files are stored in blobs as described here: https://help.sonatype.com/display/NXRM3/Repository+Management#RepositoryManagement-BlobStores
You will not find the physical files in your storage like you did in Nexus Repository 2. The database has references to the blobs and does all the work under the covers to retrieve them from your build tools and UI when called.
