How can I Link Jira issues to an epic using java and REST

[sajeev]

I could create Jira issues through the Java and REST service by following this Link. Now I want to link the Jira issues(like Tasks) to the already created epic in the project. How can I do this through java code. I have my epic ID(say SALES-1).

Hi sajeev!

Under your link is some basic "home made" JIRA REST client. If you intent to stay with it, you need to extend it with a method that wraps JIRA REST /rest/api/2/issueLink call: https://docs.atlassian.com/jira/REST/latest/#d2e2783

Or you can use implementation from Atlassian: https://marketplace.atlassian.com/plugins/com.atlassian.jira.jira-rest-java-client

The code snippet for REST Java Client for JIRA:

issueRestClient.linkIssue(linkIssueInput);

and javadoc for linkIssueInput:

 https://docs.atlassian.com/jira-rest-java-client-api/2.0.0-m31/jira-rest-java-client-api/apidocs/

Thank you for rerouting. I tried the tutorial code here(https://ecosystem.atlassian.net/wiki/display/JRJC/Tutorial) and solved all the dependencies(https://ecosystem.atlassian.net/wiki/display/JRJC/Project+Dependencies). But I am getting the Exception as follows ======== May 28, 2015 7:05:46 PM com.sun.jersey.api.client.ClientResponse getEntity SEVERE: A message body reader for Java class org.codehaus.jettison.json.JSONObject, and Java type class org.codehaus.jettison.json.JSONObject, and MIME media type application/json; charset=UTF-8 was not found May 28, 2015 7:05:46 PM com.sun.jersey.api.client.ClientResponse getEntity SEVERE: The registered message body readers compatible with the MIME media type are: */* -> com.sun.jersey.core.impl.provider.entity.FormProvider com.sun.jersey.core.impl.provider.entity.StringProvider com.sun.jersey.core.impl.provider.entity.ByteArrayProvider com.sun.jersey.core.impl.provider.entity.FileProvider com.sun.jersey.core.impl.provider.entity.InputStreamProvider com.sun.jersey.core.impl.provider.entity.DataSourceProvider com.sun.jersey.core.impl.provider.entity.XMLJAXBElementProvider$General com.sun.jersey.core.impl.provider.entity.ReaderProvider com.sun.jersey.core.impl.provider.entity.DocumentProvider com.sun.jersey.core.impl.provider.entity.SourceProvider$StreamSourceReader com.sun.jersey.core.impl.provider.entity.SourceProvider$SAXSourceReader com.sun.jersey.core.impl.provider.entity.SourceProvider$DOMSourceReader com.sun.jersey.core.impl.provider.entity.XMLRootElementProvider$General com.sun.jersey.core.impl.provider.entity.XMLListElementProvider$General com.sun.jersey.core.impl.provider.entity.XMLRootObjectProvider$General com.sun.jersey.core.impl.provider.entity.EntityHolderReader Exception in thread "main" com.atlassian.jira.rest.client.RestClientException: com.sun.jersey.api.client.ClientHandlerException: A message body reader for Java class org.codehaus.jettison.json.JSONObject, and Java type class org.codehaus.jettison.json.JSONObject, and MIME media type application/json; charset=UTF-8 was not found at com.atlassian.jira.rest.client.internal.jersey.AbstractJerseyRestClient.invoke(AbstractJerseyRestClient.java:75) at com.atlassian.jira.rest.client.internal.jersey.AbstractJerseyRestClient.getAndParse(AbstractJerseyRestClient.java:80) at com.atlassian.jira.rest.client.internal.jersey.JerseyIssueRestClient.getIssue(JerseyIssueRestClient.java:108) at JiraClient.main(JiraClient.java:32) Caused by: com.sun.jersey.api.client.ClientHandlerException: A message body reader for Java class org.codehaus.jettison.json.JSONObject, and Java type class org.codehaus.jettison.json.JSONObject, and MIME media type application/json; charset=UTF-8 was not found at com.sun.jersey.api.client.ClientResponse.getEntity(ClientResponse.java:549) at com.sun.jersey.api.client.ClientResponse.getEntity(ClientResponse.java:506) at com.sun.jersey.api.client.WebResource.handle(WebResource.java:674) at com.sun.jersey.api.client.WebResource.get(WebResource.java:191) at com.atlassian.jira.rest.client.internal.jersey.AbstractJerseyRestClient$1.call(AbstractJerseyRestClient.java:84) at com.atlassian.jira.rest.client.internal.jersey.AbstractJerseyRestClient.invoke(AbstractJerseyRestClient.java:54) ... 3 more ========= I am trying the Jira client as the java project in eclipse[Just created as New Java Project in Eclipse]. I am not aware of the maven and all. Am I missing any other jar dependency? Or anything should I add to my java project.
