How to get IssueManager properly ?

Albert Cameron

I always got the IssueManager the following way:

ComponentAccessor.getIssueManager()

Now in my friend's code I saw another way:

@JiraImport
private IssueManager issueManager;

So is there any difference in the 2 approaches ? What is better ? I really liked using ComponentAccessor.

In general I find it quite interesting that there are always at least 2 ways to get a specific object. For example to get the attachments of an issue , you can get it from issue itself all via the AttachmentManager.

Hi @Albert Cameron the second way is clearer as it uses dependency injection principle of OSGi framework which is used by Jira (https://dzone.com/articles/osgi-dependency-injection). So I really suggest you to use @JiraImport annotation

More information about annotations, OSGi and Spring Scanner is here: https://bitbucket.org/atlassian/atlassian-spring-scanner/src/master/

Albert Cameron

public class MyClassextends AbstractJiraFunctionProvider
{
private static final Logger LOGGER = LoggerFactory.getLogger(MyClass.class);

    @JiraImport
    private WorkflowManager workflowManager;
    @JiraImport
    private JiraAuthenticationContext authenficationContext;
    @JiraImport
    private IssueManager issueManager;
    @JiraImport
    private AttachmentManager attachmentManager;

In this case all the @JiraImport annotations were not working. All the objects were null. So I had to use ComponentAccessor. Am I missing an annotation above the class. Is the class not registered as a possible bean ?

Can you check what spring-scanner dependencies do you use in your pom.xml file? It should be something like:


<dependency>
    <groupId>com.atlassian.plugin</groupId>
    <artifactId>atlassian-spring-scanner-annotation</artifactId>
    <version>${atlassian.spring.scanner.version}</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>com.atlassian.plugin</groupId>
    <artifactId>atlassian-spring-scanner-annotation</artifactId>
    <version>${atlassian.spring.scanner.version}</version>
    <scope>provided</scope>
</dependency>

<atlassian.spring.scanner.version>2.0.0</atlassian.spring.scanner.version>

and also I use this:

<plugin>
    <groupId>com.atlassian.plugin</groupId>
    <artifactId>atlassian-spring-scanner-maven-plugin</artifactId>
    <version>${atlassian.spring.scanner.version}</version>
    <executions>
        <execution>
            <goals>
                <goal>atlassian-spring-scanner</goal>
            </goals>
            <phase>process-classes</phase>
        </execution>
    </executions>
    <configuration>
        <scannedDependencies>
            <dependency>
                <groupId>com.atlassian.plugin</groupId>
                <artifactId>atlassian-spring-scanner-external-jar</artifactId>
            </dependency>
        </scannedDependencies>
        <verbose>false</verbose>
    </configuration>
</plugin>
