I cross checked, jar file available in class path.enter image description here

Spring Boot Actuators endpoints could not be picked-up if running within IDE(IntelliJ or Eclipse).

I tried to run jar using below command(outside of IDE) on cmd and it worked for me.

c:\workspace\demo\target\java -jar demo-spring-boot-project.jar

And I was able to access below URL

http://localhost:8090/actuator/health

Encountered this too while running the app through InteliJ IDEA. It turns out I added the spring-boot-starter-actuator dependency but did not tell Maven to reload the project.

Right clicking on the pom.xml file and selecting Maven->Reload project, solved it.

*In this case I see the jar file exists in your classpath, so your problem is different than mine. Leaving this comment so it might help someone else.

I have encountered the same issue while running the project through IntelliJ IDE. I resolved after doing Invalidate Cache & Restart in IntelliJ IDE.

Go to File -> ``Invalidate Cache`.

The Invalidate cache dialog box appears. One can select accordingly to their project.
