Launching Service with --deployer=thin fails

[BoykoAlex]

Install Boot CLI 2.2.7 or 2.3.0
Install the latest Cloud CLI 2.2.1 in it
Launch eureka service: ./bin/spring cloud eureka --deployer=thin fails
Launch without --deployer=thin works fine - service launched

@BoykoAlex is there an error message?
@dsyer any thoughts?

With 2.2.7 Boot CLI it just shuts down without the errors.

With 2.3.0 Boot CLI there is a stack trace:

There must be an issue with the config file, but "thin" is the default, so if that's what you needed it already works, I guess.

CORRECTION: the default is "local". I'll check the config.

CORRECTION: the default is "local" but the apps are all thin jars, so they get deployed using a thin launcher by default.

So what was it you wanted to achieve with the "thin" profile? I guess it keeps all the apps running in the same JVM. That's a valid goal, so I'll try and find a fix.

You can workaround the problem by putting an explicit version in thin-thin.properties BTW (in the spring-cloud-launcher-deployer jar), e.g.

exclusions.spring-cloud-deployer-local: org.springframework.cloud:spring-cloud-deployer-local
dependencies.spring-cloud-deplyer-thin: org.springframework.cloud:spring-cloud-deployer-thin:1.0.22.RELEASE
