Boot 2.6.x beans form a cycle

[bgaborg]

When using spring boot 2.6.0 with spring shell 2.0.1-RELEASE I get the following error during startup:

2021-11-19 20:50:30.252 ERROR 18591 --- [           main] o.s.b.d.LoggingFailureAnalysisReporter   : 

***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

┌──->──┐
|  org.springframework.shell.result.ResultHandlerConfig
└──<-──┘


Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

From pom.xml:

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.6.0</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

and

	<dependencies>
		<dependency>
			<groupId>org.springframework.shell</groupId>
			<artifactId>spring-shell-starter</artifactId>
			<version>2.0.1.RELEASE</version>
		</dependency>
	</dependencies>

workaround: use spring-boot-starter-parent version 2.5.7. It took some time to figure this out though, maybe helps for someone else.

Yes, confirmed that v2.5.7 of spring-boot-starter-parent is a good work-around for this issue.

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.5.7</version>

workaround: only for test or dev experiments
spring-boot-starter-parent 2.6.0
and here we go - spring.main.allow-circular-references=true
the dirty hack )
