SAL Service Tutorial

[Andrew Pechnikov]

Hi all.
Dear community, help me please. I'm totally stuck. Im doing a JIRA SAL service and im following https://developer.atlassian.com/display/DOCS/Scheduling+Events+via+SAL+Tutorial .

Please note, that's not first time im doing a service, did 3-4 services last year. As mentioned, I wrote Job, Scheduler interface and SchedulerImpl classes.

This service is SO simple, just write smth to log on launch.
After Installing plugin with it I catch error, please help me to solve this.
I tried to reboot system, manage dependencies in pom.xml, tried different keys for modules in atlassian-plugin.xml, also played a game "Find 10 differencies between this service and one you made a year ago".
Thanks in advance, Andrey.
Mine atlassian-plugin.xml:

<component key="UpdateFieldSchedulerComponentTwo" class="ru.borlas.jira.service.UpdateCustomerCascFieldSchedulerImpl"
               system="true" public="true">
        <description></description>
        <interface>com.atlassian.sal.api.lifecycle.LifecycleAware</interface>
        <interface>ru.borlas.jira.service.UpdateCustomerCascFieldScheduler</interface>
    </component>
    <component-import key="cfUpdatePluginSchedulerTwo">
        <description>SAL Scheduler</description>
        <interface>com.atlassian.sal.api.scheduling.PluginScheduler</interface>
    </component-import>

Mine scheduler:

public class UpdateCustomerCascFieldSchedulerImpl implements UpdateCustomerCascFieldScheduler, LifecycleAware {

    /* package */ static final String KEY = UpdateCustomerCascFieldSchedulerImpl.class.getName() + ":instance";
    private static final String JOB_NAME = UpdateCustomerCascFieldSchedulerImpl.class.getName() + ":job";

    private final Logger logger = Logger.getLogger(UpdateCustomerCascFieldSchedulerImpl.class);
    private final PluginScheduler pluginScheduler;  // provided by SAL
    private long interval = 5000L;

    public UpdateCustomerCascFieldSchedulerImpl(PluginScheduler pluginScheduler) {
        this.pluginScheduler = pluginScheduler;
    }


    //@Override
    public void onStart() {
        reschedule(interval);
    }

    //@Override
    public void reschedule(long interval) {
        this.interval = interval;

        pluginScheduler.scheduleJob(
                JOB_NAME,                   // unique name of the job
                UpdateCustomerscCascadingFieldJob.class,     // class of the job
                new HashMap<String, Object>() {{
                    put(KEY, UpdateCustomerCascFieldSchedulerImpl.this);
                }},                         // data that needs to be passed to the job
                new Date(),                 // the time the job is to start
                interval);                  // interval between repeats, in milliseconds
        logger.info(String.format("Twitter search task scheduled to run every %dms", interval));
    }
}

Mine Job:

public class UpdateCustomerscCascadingFieldJob implements PluginJob {

    private final Logger logger = Logger.getLogger(UpdateCustomerscCascadingFieldJob.class);

    /**
     * Executes this job.
     *
     * @param jobDataMap any data the job needs to execute. Changes to this data will be remembered between executions.
     */
    public void execute(Map<String, Object> jobDataMap) {

        final UpdateCustomerCascFieldSchedulerImpl update = (UpdateCustomerCascFieldSchedulerImpl)jobDataMap.get(UpdateCustomerCascFieldSchedulerImpl.KEY);
        assert update != null;
        logger.log(Priority.toPriority(Priority.ERROR_INT), "Job is running");

            //update.setLastRun(new Date());

    }
}

And the error:

And so on

Did you fix this issue?

I also tried to install service manually and got his error:

Error adding service: org.picocontainer.injectors.AbstractInjector$UnsatisfiableDependenciesException: ru.borlas.jira.service.UpdateCustomerCascFieldSchedulerImpl has unsatisfied dependency 'interface com.atlassian.sal.api.scheduling.PluginScheduler' for constructor 'public ru.borlas.jira.service.UpdateCustomerCascFieldSchedulerImpl(com.atlassian.sal.api.scheduling.PluginScheduler)' from org.picocontainer.DefaultPicoContainer@7933e7a1:1<[Immutable]:com.atlassian.jira.component.CachingMutablePicoContainer@3eac3931.
