This application tests connectivity to JIRA REST Web Services in a 
manor similar to P4DTG's JIRA-TEST plugin.

To Install:

Download jiraRestAccess.zip

Unzip to a scratch directory.  This will create two files:

  jiraRestAccess.jar
  lib/jira-rest-all-dependencies.jar

To Run:

From that scratch directory:

To show the syntax:

   java -jar jiraRestAccess.jar
   
To connect and get the Server's date - this tests connectivity to jira:

   java -jar jiraRestAccess.jar http://<jira-host:port> <user>:<password>

To retrieve an existing issue - this test permissions on the issue:

   java -jar jiraRestAccess.jar http://<jira-host:port> <user>:<password> <issue-id>
   
To update an issue.  This appends the last argument <chars> to the issue's summary:

   java -jar jiraRestAccess.jar http://<jira-host:port> <user>:<password> <issue-id> <chars>
   

To run a query:

   java -jar jiraRestAccess.jar http://jira-host:port> <user>:<password> query "<jql>"
   
   The jira query language (jql) string is what you can type into the JIRA UI's Advanced search.
   
   Use -Dbatch_size=NN to alter the batch size from the default 100.  Example below.  
   This corresponds to the jira source's defect_batch attribute.
   
Notes:

If you don't provide a password on the command line then we'll prompt for it.

You can test JIRA connectivity with either http or https, just provide the proper URL. 

If you receive SSL related exceptions with an https site, see the 
"Common Exceptions" section in http://answers.perforce.com/articles/KB/3578
