I got a Sonatype Nexus instance up and running and need to write a script to download a specific artifact manually.

I tried using the REST API and wget:

wget --user=username --password=password http://<ip>:<port>/nexus/service/local/artifact/maven/content?g=<group>&a=<artifact>&v=<version>&r=snapshots

Resolving <ip stuff>
Connecting to <ipv6 stuff>... failed: Connection refused.
Connecting to <ipv4 stuff>... connected.
HTTP request sent, awaiting response... 401 Unauthorized
Reusing existing connection to <ip>:<port>.
HTTP request sent, awaiting response... 400 Bad Request
2014-05-11 20:17:01 ERROR 400: Bad Request.

Does anyone know, how to get this to work?

Edit: I'm able to download the artifact using my browser (and being logged in to the webinterface)

The URL looks correct, but you're to have to quote it because it contains special characters.

wget --user=username --password=password "http://<ip>:<port>/nexus/service/local/artifact/maven/content?g=<group>&a=<artifact>&v=<version>&r=snapshots"

You also might want to add --content-disposition in order for the downloaded file name to be correct. See here for more information:

  • is there one for powershell? i got this on ps , Invoke-WebRequest : A positional parameter cannot be found that accepts argument '--password=admin123'. here is the command: wget --user=admin --password=admin123 "http://ec2-54-299-XX-231.us-west-2.compute.amazonaws. com:8081/nexus/service/local/artifact/maven/content?g=org&a=foo&v=1.0&r=releases" – OK999 Apr 27 '16 at 20:39
  • Your Sonatype link is broken: `The page you were looking for doesn't exist` – Boris Mar 24 '22 at 17:03

for nexus 3 

wget --user=userid --password=password 'https://nexusurl:8081/nexus/repository/<repository id>/<replace the grouf is . with />/<artifact id>/<version>/<file name>' -O ${WORKSPACE}/<new file name>

example

group id =com.sap.cloudfoundry.mta_plugin_linux

artifact id =com.sap.cloudfoundry.mta_plugin_linux.api

nexus url = alm.xxxxxx.com

$WORKSPACE=jenkins present workspace

new filename=cf-cli-mta-plugin-2.0.3-linux-x86_64.bin

repository id = Sample_Replatform_Stage_2_Release (this you see as the name of the repo)

The command will be 

 wget --user=USERID --password=PASSWORD 'https://alm.xxxxxxx.com/nexus/repository/sample_Replatform_Stage_2_Release/com/sap/cloudfoundry/mta_plugin_linux/com.sap.cloudfoundry.mta_plugin_linux.api/2.0.3/com.sap.cloudfoundry.mta_plugin_linux.api-2.0.3.bin' -O ${WORKSPACE}/cf-cli-mta-plugin-2.0.3-linux-x86_64.bin

most importantly for nexus rest api the artifactID-version should always match the filename else you will get the maven2 repository format error

for additional arguments and formats you may look in https://support.sonatype.com/hc/en-us/articles/213465488-How-can-I-retrieve-a-snapshot-if-I-don-t-know-the-exact-filename-

GNU Wget 1.20.3 built on darwin19.0.0. goes like this:
