Hi there,

At current time there is not a REST endpoint to do this. REST is coming in the future however, stay tuned!

Never like hearing that. There's a potential (if you want to work with me), to use our Provisioning API:


Of note, you would need to write a Groovy Script that handles your current use case. We don't have anything on hand at current time that accomplishes what you are asking for, but this is certainly a use case that people ask for.

While there is no REST API as such you can easily download any artifact from v3. Just instead of using GAV parameters against the API.. you use the same parameters to assemble the URL of the artifact and then just download it with wget or curl. 

For a specific artifact you can also just use the web user interface of the server to locate it and in the assets use direct link provided. It shows the full url

E.g. it could be something like

wget http://localhost:8081/repository/maven-public/junit/junit/4.12/junit.jar

 

That works just fine.

Very true. Went flying right over my head, if the use case is just this simple you can assemble the URL Manfred pointed out. The part that threw me, and I'm not sure if it matters to you is the snapshot, release filter, as well as the v=latest from the linked Support article in the Stack Overflow link (https://support.sonatype.com/hc/en-us/articles/213465488-How-can-I-retrieve-a-snapshot-if-I-don-t-know-the-exact-filename-). You can work around the release/snapshot by making a request to the specific repository, latest is what we don't have yet.

I have been looking for this as well. Can you please elaborate how would we fetch the snapshots ? I was unable to download it using the snapshot version. Only if I use the timestamp in the version can I get the snapshots. Maybe I am missing something here.

Please advise.

Harpreet

You have to download the maven-metadata.xml file, parse and interpret
it and then assemble the filename with the parameters from the file.

If you are comfortable with parsing XML, you can generate wget URL's from maven metadata.

https://NEXUS/repository/maven-public/GROUP/ID/ARTIFACT-ID/maven-metadata.xml to get a list of versions including latest and latest release

With this you can generate URL for full releases

Is it possible to delete artifacts this way?

If you know the direct content URL for a Maven artifact inside a hosted or proxy repository, you can send an HTTP DELETE request to delete that path from the repository.

Turns out my mistake was not realizing that the elements of the artifact groupID need to be separated by slashes and not dots.

I used your idea and wrote this bare bones bash script to parse the metadata.

Here's my bash script to get the RELEASE

if [ "${VERSION}" == "RELEASE" ]; then
  VERSION=`cat mavenmeta.xml | grep release | sed 's/release//g ; s/[\<\>\/ ]//g'`
fi


WARNAME="dashboard-${VERSION}.war"

curl ${URL} -o ${WARNAME} -k

Jeffry,

Can we get an update as to where this is?

It's pretty crucial functionality. Thanks!
