How can I retrieve the content of the requested artifact for Nexus 3 like /service/local/artifact/maven/content in Nexus 2 ?
I didn't see any script API in Intellij IDEA.
Which API can I use for that maven artifact operations like getting artifact, listing artifact names version numbers etc... ?
There is no API for getting artifacts, listing artifact names, version numbers etc. The REST API will probably include these features when it is implemented.
As mentioned, there is currently no REST API in Nexus Repository Manager 3, but one will be coming at a later date. An alternative for the time being is to use our Scripting API to accomplish what you need, as it allows you to roll your own REST API:
