Jira Component

Since Camel 3.0

Both producer and consumer is supported

The JIRA component interacts with the JIRA API by encapsulating Atlassian’s REST Java Client for JIRA. It currently provides polling for new issues and new comments. It is also able to create new issues, add comments, change issues, add/remove watchers, add attachment and transition the state of an issue.

Rather than webhooks, this endpoint relies on simple polling. Reasons include:

  • Concern for reliability/stability

  • The types of payloads we’re polling aren’t typically large (plus, paging is available in the API)

  • The need to support apps running somewhere not publicly accessible where a webhook would fail

Note that the JIRA API is fairly expansive. Therefore, this component could be easily expanded to provide additional interactions.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jira</artifactId>
    <version>${camel-version}</version>
</dependency>

URI format

jira://type[?options]

JIRA Options

The Jira component supports 4 options, which are listed below.

Name Description Default Type

configuration (advanced)

The JiraConfiguration parameters

JiraConfiguration

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

The Jira type accepts the following operations:

For consumers:

  • newIssues: retrieve only new issues after the route is started

  • newComments: retrieve only new comments after the route is started

For producers:

  • addIssue: add an issue

  • addComment: add a comment on a given issue

  • attach: add an attachment on a given issue

  • deleteIssue: delete a given issue

  • updateIssue: update fields of a given issue

  • transitionIssue: transition a status of a given issue

  • watchers: add/remove watchers of a given issue

As Jira is fully customizable, you must assure the fields IDs exists for the project and workflow, as they can change between different Jira servers.

The Jira endpoint is configured using URI syntax:

jira:type

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

type

Required Operation to perform. Consumers: NewIssues, NewComments. Producers: AddIssue, AttachFile, DeleteIssue, TransitionIssue, UpdateIssue, Watchers. See this class javadoc description for more information.

JiraType

Query Parameters (16 parameters):

Name Description Default Type

delay (common)

Time in milliseconds to elapse for the next poll.

6000

Integer

jiraUrl (common)

Required The Jira server url, example: http://my_jira.com:8081

String

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

jql (consumer)

JQL is the query language from JIRA which allows you to retrieve the data you want. For example jql=project=MyProject Where MyProject is the product key in Jira. It is important to use the RAW() and set the JQL inside it to prevent camel parsing it, example: RAW(project in (MYP, COM) AND resolution = Unresolved)

String

maxResults (consumer)

Max number of issues to search for

50

Integer

exceptionHandler (consumer)

To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.

ExceptionHandler

exchangePattern (consumer)

Sets the exchange pattern when the consumer creates an exchange.

ExchangePattern

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

String

username (security)

String

Spring Boot Auto-Configuration

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-jira-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

Client Factory

You can bind the JiraRestClientFactory with name JiraRestClientFactory in the registry to have it automatically set in the Jira endpoint.

Authentication

We recommend to use OAuth whenever possible, as it provides the best security for your users and system.

Basic authentication requirements:

  • An username and password

OAuth authentication requirements:

Follow the tutorial in Jira OAuth documentation to generate the client private key, consumer key, verification code and access token.

  • a private key, generated locally on your system.

  • A verification code, generated by Jira server.

  • The consumer key, set in the Jira server settings.

  • An access token, generated by Jira server.

JQL:

The JQL URI option is used by both consumer endpoints. Theoretically, items like "project key", etc. could be URI options themselves. However, by requiring the use of JQL, the consumers become much more flexible and powerful.

At the bare minimum, the consumers will require the following:

jira://[type]?[required options]&jql=project=[project key]

One important thing to note is that the newIssues consumer will automatically set the JQL as:

  • append ORDER BY key desc to your JQL

  • prepend id > latestIssueId to retrieve issues added after the camel route was started.

This is in order to optimize startup processing, rather than having to index every single issue in the project.

Another note is that, similarly, the newComments consumer will have to index every single issue and comment in the project. Therefore, for large projects, it’s vital to optimize the JQL expression as much as possible. For example, the JIRA Toolkit Plugin includes a "Number of comments" custom field — use '"Number of comments" > 0' in your query. Also try to minimize based on state (status=Open), increase the polling delay, etc. Example:

jira://[type]?[required options]&jql=RAW(project=[project key] AND status in (Open, \"Coding In Progress\") AND \"Number of comments\">0)"

Operations

See a list of required headers to set when using the Jira operations. The author field for the producers is automatically set to the authenticated user in the Jira side.

If any required field is not set, then an IllegalArgumentException is throw.

There are operations that requires id for fields suchs as: issue type, priority, transition. Check the valid id on your jira project as they may differ on a jira installation and project workflow.
