Spring cloud starter task : Not able to work on Spring boot 2.x

I was trying to make spring boot batch application(2.0.0.RC1) work with Spring cloud starter task(2.0.0.M2). Getting a range of errors while making Spring cloud starter task work with spring boot 2.x batch application.

I was able to run batch applicationspring-boot-starter-parent(1.5.10.RELEASE) with Spring cloud starter task(2.0.0.M2) successfully.

But when I tried Spring cloud starter task(2.0.0.M2) with spring boot 2.0.0.RC1, I am getting following error.

com.fasterxml.jackson.databind.exc.InvalidTypeIdException: Could not resolve type id '' into a subtype of [simple type, class java.lang.Object]:

Here is the screenshot of the same. enter image description here

So I decided to downgrade Spring boot to 2.0.0.M7.Alas I am getting a different exception.

java.lang.IllegalStateException: org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext@61f78561 has been closed already.

Why this exceptions happens?Any help/guide would be appreciated.

Solution

  • There have been quite a few upstream changes in Spring Boot, which caused side effects in Spring Cloud Task's 2.0.

    We have had a all of them resolved (some in Boot itself) - see here.

    We are targeting a 2.0 M3 release this week, so until that is done, perhaps you could try building 2.0 BUILD-SNAPSHOT locally. If you see any other anomaly, please let us know.
