Just to create a separate answer  The answer is actually found in a comment for the accepted answer   Try changing the version of your artefact to end with -SNAPSHOT

Ensure that not exists already  artifact and version  in nexus  as release   In that case return Bad Request

This can also happen if you have a naming policy around version  prohibiting the version  you are trying to deploy  In my case I was trying to upload a version  to release repo  2 0 1 but later found out that our nexus configuration doesn t allow anything other than whole number for releases    I tried later with version 2 and deployed it successfully   The error message definitely dosen t help   Return code is  400  ReasonPhrase  Repository does not allow updating assets  maven-releases-xxx  - gt   Help 1    A better message could have been version 2 0 1 violates naming policy

For 400 error  check the repository  Deployment policy  usually its  Disable redeploy   Most of the time your library version is already there that is why you received a message  Could not PUT put  https   yoururl some jar   Received status code 400 from server  Repository does not allow updating assets   your repository name     So  you have a few options to resolve this  1- allow redeploy 2- delete the version from your repository which you are trying to upload  3- change the version number

Server id should match with the repository id of maven settings xml

In the rare event that you need to redeploy the SAME STABLE artifact to Nexus  it will fail by default  If you then delete the artifact from Nexus  via the web interface  for the purpose of deploying it again  the deploy will still fail  since just removing the e g  jar or pom does not clear other files still laying around in the directory  You need to log onto the box and delete the directory in its entirety

Cause of problem for me was -source jars was getting uploaded twice  with maven-source-plugin  as mentioned as one of the cause in accepted answer  Redirecting to answer that I referred  Maven release plugin fails   source artifacts getting deployed twice

I had this exact problem today and the problem was that the version I was trying to release perform was already in the Nexus repo   In my case this was likely due to a network disconnect during an earlier invocation of release perform   Even though I lost my connection  it appears the release succeeded

400 Bad Request will be returned if you attempt to    Deploy a snapshot artifact  or version  ending in -SNAPSHOT to a release repository Deploy a release artifact  version not ending in -SNAPSHOT  to a snapshot repository Deploy the same version of a release artifact more than once to a release repository

User · Answer

in the parent pom application    Version put the tag as follows  x x x-SNAPSHOT   example  0 0 1-SNAPSHOT    -SNAPSHOT    is very important

If any of the above answers worked out  You can create new artifact directly from the admin side of  NEXUS Screen shot attached below     Login to nexus UI http   YOUR URL 8081 nexus  username  admin default password  admin123   Click repositories on the left side then click the repo  For eg  click release  Choose artifact Upload  last tab    Choose GAV definition as GAV Param- Then enter your groupid   artifact id and version   Choose Jar file   Click upload artifact  Thats it     Now you will be able to add the corrsponding in your project  screenshot below

I had the same problem today with the addition  Return code is  400  ReasonPhrase  Bad Request   which turned out to be the  artifact is already deployed with that version if it is a release  problem from answer above enter link description here  One solution not mentioned yet is to configure Nexus to allow redeployment into a Release repository  Maybe not a best practice  because this is set for a reason  you nevertheless could go to  Access Settings  in your Nexus repositories    Configuration -Tab and set the  Deployment Policy  to  Allow Redeploy

A couple things I can think of    user credentials are wrong url to server is wrong user does not have access to the deployment repository user does not have access to the specific repository target artifact is already deployed with that version if it is a release  not -SNAPSHOT version  the repository is not suitable for deployment of the respective artifact  e g  release repo for snapshot version  proxy repo or group instead of a hosted repository    Check those and if you still run into trouble provide more details here
