Nexus 3 Rest api to check if component exist

问题

Maybe I miss something but i can't find a way to upload a component(jar or dll) to the nexus 3 repository from the UI. So I am trying to build a tool for this job, to optimize the upload process I need a way to check if component exist in the nexus repository programmatically, all my tries to find suitable rest api failed.

Anyone have suggestions?

At this time, the REST API has been released as beta. You can get more information and give us feedback by going to this link: http://blog.sonatype.com/nexus-repository-new-beta-rest-api-for-content

You can use some of the new endpoints to check if a component/asset exists, and then use curl or something akin depending on the format to upload it via the existing format endpoints.

Maybe you can upload a groovy script and use that script to check whether the component exists or not.

import org.sonatype.nexus.repository.storage.Query;
import org.sonatype.nexus.repository.storage.StorageFacet;
import groovy.json.JsonOutput;

def repositoryId = args.split(',')[0];
def groupId = args.split(',')[1];
def artifactId = args.split(',')[2];
def baseVersion = args.split(',')[3];
def latestOnly = args.split(',')[4];

def repo = repository.repositoryManager.get(repositoryId);
StorageFacet storageFacet = repo.facet(StorageFacet);
def tx = storageFacet.txSupplier().get();

tx.begin();
def components = tx.findComponents(Query.builder().where('group = ').param(groupId).and('name = ').param(artifactId).build(), [repo]);

def found = components.findAll{it.attributes().child('maven2').get('baseVersion')==baseVersion}.collect{
def version = it.attributes().child('maven2').get('version');\"${version}\"};

// found = found.unique().sort();
def latest = found.isEmpty() ? found : found.last();

tx.commit();
def result = latestOnly == 'latest' ? JsonOutput.toJson(latest) : JsonOutput.toJson(found);

return result;
