CURL cmd throwing error when I look to transfer the jar file from server to nexus repo Mark bundle as not supporting multiuse HTTP/1.1 405 POST

Why is the CURL command throwing following error when I look to transfer the jar file from my server to nexus repository

curl -v -F r=1 -F hasPom=false -F e=jar -F g=org.sonatype.plugins -F a=nexus-staging-maven-plugin -F v=1.0 -F p=jar -F file=mozaic-1.0-SNAPSHOT.jar -u admin:Easy123 http://192.168.12.176:8081/repository/maven-snapshots/

Solution

You're getting the following response from the Nexus server: < HTTP/1.1 405 POST. And in the HTML response body we can (also) see what HTTP 405 POST means:

Error 405 Method Not Allowed

So the POST method is not allowed on this URL. That is the result of trying to do a form upload via curl, which is not supported. The Nexus server also kindly responds with the methods it does allow: < Allow: GET,HEAD,PUT,DELETE

If you want to upload a file into a repository, you are supposed to use a HTTP PUT command. You can find the documentation for how this is executed online:

For example a direct deploy with curl for nexus 2 (and also 3, the command is the same besides the specific /repositories path):

You can do an HTTP PUT of a file into /content/repositories/<repo-id>/<path-of-file>. Using curl you can do this with:
curl -v -u admin:admin123 --upload-file pom.xml http://localhost:8081/nexus/content/repositories/releases/org/foo/1.0/foo-1.0.pom

Watch out; you're supposed to manually put the correct groupid, artifactid, version and desired filename into this URL, otherwise you'll upload the file in the root of the repository! In this example that would be the last part of the URL: org/foo/1.0/foo-1.0.pom

An example of executing this on a Nexus server i have access to:

curl -v -u user:pass --upload-file some.jar http://host/nexus/content/repositories/repo/group/artifact/version/some.jar

With curl command logging (minus REDACTED private information):

* Server auth using Basic with user 'user'
