spring batch Configuration The element is unreachable

Question

This is my job configuration:

 <step id="indelToMorph" next="multiThreaded_createIndividualMorphs_master">
            <tasklet>
                <chunk reader="indelReader" processor="indelProcessor" writer="indelWriter" commit-interval="100"/>
            </tasklet>
        </step>

        <step id="multiThreaded_createIndividualMorphs_master" next="createMarkers"> 
            <partition step="multiThreaded_createIndividualMorphs"  partitioner="partitionMorphAdvancedHandler"> 
                        <handler grid-size="10" task-executor="taskAsyncExecutor"/> 
             </partition>
            <listeners>
                <listener ref="calculateIndividualMorphListener"/>
            </listeners>
        </step>

        <step id="multiThreaded_createIndividualMorphs">
            <tasklet ref="createIndividualMorphsAdvancedTasklet"/>
        </step>

        <step id="createMarkers">
            <tasklet ref="verifyTasklet"/>
        </step>

And the beans are created:

@Bean
    @Scope("step")
    public Tasklet createIndividualMorphsAdvancedTasklet() {
        Tasklet createIndividualMorphsAdvancedTasklet = new CreateIndividualMorphsAdvancedTasklet();
        return createIndividualMorphsAdvancedTasklet;
    }

But it says:

Caused by: org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: The element [multiThreaded_createIndividualMorphs] is unreachable

What I am missing?

in your job flow the step multiThreaded_createIndividualMorphs can not be reached as in there is no next configuration which points to this step

The problem was related with the declaration of the step. In order to use the step in a partition step, the slaves steps need to be define out of the job:

<job>
</job>
<step id="multiThreaded_createIndividualMorphs" xmlns="http://www.springframework.org/schema/batch">
            <tasklet ref="createIndividualMorphsAdvancedTasklet"/>
     </step>
