Upload artifacts to Nexus without Maven

Question

I have a non-Java project that produces a versioned build artifact  and I want to upload this to a Nexus repository  Because the project isn t Java  it doesn t use Maven for builds  And I d rather not introduce Maven POM files just to get files into Nexus   The links on blogs to the Nexus REST API all end up at a sign-in wall  with no  create user  link that I can see   So  what s the best  or any reasonable  way to upload build artifacts to a Nexus repository without Maven   bash   curl  would be great  or even a Python script

You can use curl instead   version 1 2 3 artifact  artifact  repoId repositoryId groupId org myorg REPO URL http   localhost 8081 nexus  curl -u username password --upload-file filename tgz  REPO URL content repositories  repoId  groupId  artefact  version  artifact- version tgz

If you need a convenient command line interface or python API  look at repositorytools  Using it  you can upload artifact to nexus with command  artifact upload foo-1 2 3 ext releases com fooware   To make it work  you will also need to set some environment variables  export REPOSITORY URL https   repo example com export REPOSITORY USER admin export REPOSITORY PASSWORD mysecretpassword

You can manually upload the artifact s by clicking on upload artifacts button in the Nexus server and provide the necessary GAV properties for uploading it s generally the file structure for storing the artifact

You can ABSOLUTELY do this without using anything MAVEN related  I personally use the NING HttpClient  v1 8 16  to support java6    For whatever reason  Sonatype makes it incredibly difficulty to figure out what the correct URLs  headers  and payloads are supposed to be  and I had to sniff the traffic and guess    There are some barely useful blogs documentation there  however it is either irrelevant to oss sonatype org  or it s XML based  and I found out it doesn t even work   Crap documentation on their part  IMHO  and hopefully future seekers can find this answer useful  Many thanks

No need to use these commands    you can directly use the nexus web Interface in order to upload your JAR using GAV parameters     So it is very simple

The calls that you need to make against Nexus are REST api calls     The maven-nexus-plugin is a Maven plugin that you can use to make these calls   You could create a dummy pom with the necessary properties and make those calls through the Maven plugin   Something like   mvn -DserverAuthId sonatype-nexus-staging -Dauto true nexus staging-close   Assumed things    You have defined a server in your    m2 settings xml named sonatype-nexus-staging with your sonatype user and password set up - you will probably already have done this if you are deploying snapshots   But you can find more info here    Your local settings xml includes the nexus plugins as specified here  The pom xml sitting in your current directory has the correct Maven coordinates in its definition   If not  you can specify the groupId  artifactId  and version on the command line  The -Dauto true will turn off the interactive prompts so you can script this    Ultimately  all this is doing is creating REST calls into Nexus   There is a full Nexus REST api but I have had little luck finding documentation for it that s not behind a paywall   You can turn on the debug mode for the plugin above and figure it out however by using -Dnexus verboseDebug true -X   You could also theoretically go into the UI  turn on the Firebug Net panel  and watch for  service POSTs and deduce a path there as well

You can also use the direct deploy method using curl  You don t need a pom for your file for it but it will not be generated as well so if you want one  you will have to upload it separately   Here is the command   version 1 2 3 artefact  myartefact  repoId yourrepository groupId org myorg REPO URL http   localhost 8081 nexus  curl -u nexususername nexuspassword --upload-file filename tgz  REPO URL content repositories  repoId  groupId  artefact  version  artefact- version tgz
