I have created a simple job in Spring Batch with Spring Boot to be executed as a task with Spring Cloud Task (all in STS4). If I execute it as a Spring Boot App, te execution is correct and without problems, but if I compile the project or try to launch the test, the execution of the job is correct:
o.s.c.t.b.l.TaskBatchExecutionListener : The job execution id 19 was run within the task execution 56
o.s.batch.core.job.SimpleStepHandler : Executing step: [step1]
com.example.demo.MyTasklet : Executing Tasklet: STEP 1
o.s.batch.core.step.AbstractStep : Step: [step1] executed in 16ms
o.s.batch.core.job.SimpleStepHandler : Executing step: [step2]
com.example.demo.MyTasklet : Executing Tasklet: STEP 2
o.s.batch.core.step.AbstractStep : Step: [step2] executed in 7ms
o.s.b.c.l.support.SimpleJobLauncher : Job: [FlowJob: [name=job2]] completed with the following parameters: [{run.id=7, -spring.output.ansi.enabled=always}] and the following status: [COMPLETED] in 52ms
com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Shutdown initiated...
com.zaxxer.hikari.HikariDataSource : HikariPool-1 - Shutdown completed.
com.zaxxer.hikari.HikariDataSource : HikariPool-2 - Shutdown initiated...
com.zaxxer.hikari.HikariDataSource : HikariPool-2 - Shutdown completed.
But after that, it happends an exception:
o.s.test.context.TestContextManager : Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener@576d5deb] to prepare test instance [com.example.demo.DemoJobApplicationTests@173ed316]
java.lang.IllegalStateException: The ApplicationContext loaded for [[MergedContextConfiguration@e350b40 testClass = DemoJobApplicationTests, locations = '{}', classes = '{class com.example.demo.DemoJobApplication}', contextInitializerClasses = '[]', activeProfiles = '{}', propertySourceLocations = '{}', propertySourceProperties = '{org.springframework.boot.test.context.SpringBootTestContextBootstrapper=true}', contextCustomizers = set[org.springframework.boot.test.context.filter.ExcludeFilterContextCustomizer@5e82df6a, org.springframework.boot.test.json.DuplicateJsonObjectContextCustomizerFactory$DuplicateJsonObjectContextCustomizer@50a638b5, org.springframework.boot.test.mock.mockito.MockitoContextCustomizer@0, org.springframework.boot.test.web.client.TestRestTemplateContextCustomizer@130161f7, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@0, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizerFactory$Customizer@479d31f3], contextLoader = 'org.springframework.boot.test.context.SpringBootContextLoader', parent = [null]]] is not active. This may be due to one of the following reasons: 1) the context was closed programmatically by user code; 2) the context was closed during parallel test execution either according to @DirtiesContext semantics or due to automatic eviction from the ContextCache due to a maximum cache size policy.
at org.springframework.util.Assert.state(Assert.java:94) ~[spring-core-5.2.3.RELEASE.jar:5.2.3.RELEASE]
at org.springframework.test.context.support.DefaultTestContext.getApplicationContext(DefaultTestContext.java:127) ~[spring-test-5.2.3.RELEASE.jar:5.2.3.RELEASE]
[...]
This makes that the compilation ends in fail, but the execution in the database is recorded as COMPLETED. Reviewing the code where the error is generated, in the Spring class called DefaultTestContext:
@Override
public ApplicationContext getApplicationContext() {
ApplicationContext context = this.cacheAwareContextLoaderDelegate.loadContext(this.mergedContextConfiguration);
if (context instanceof ConfigurableApplicationContext) {
@SuppressWarnings("resource")
ConfigurableApplicationContext cac = (ConfigurableApplicationContext) context;
Assert.state(cac.isActive(), () ->
"The ApplicationContext loaded for [" + this.mergedContextConfiguration +
"] is not active. This may be due to one of the following reasons: " +
"1) the context was closed programmatically by user code; " +
"2) the context was closed during parallel test execution either " +
"according to @DirtiesContext semantics or due to automatic eviction " +
"from the ContextCache due to a maximum cache size policy.");
}
return context;
}
... the problem is that "context" is not active.

I have tried several annotations like @DirtiesContext, @EnableAutoConfiguration, @SpringBatchTest... but nothing seems to solve the issue, so I would appreciate any idea or help.
