Question

I am in my first hour of Spring Cloud education. Trying to follow directions here to start Eureka. But encounter an IllegalStateException for spring-boot-thin-launcher. Appreciate any pointers on what I could be doing wrong.

Spring Boot CLI installation:

Step 1

$ sdk install springboot 1.5.3.RELEASE

Found a previously downloaded springboot 1.5.3.RELEASE archive. Not downloading it again...

Installing: springboot 1.5.3.RELEASE
Done installing!

Do you want springboot 1.5.3.RELEASE to be set as default? (Y/n): Y

Setting springboot 1.5.3.RELEASE as default.

Step 2:

$ sdk use springboot 1.5.3.RELEASE // Redundant but executing just to be sure

Using springboot version 1.5.3.RELEASE in this shell.

Installing Spring Cloud CLI:

$ spring install org.springframework.cloud:spring-cloud-cli:1.3.1.RELEASE
Installing into: /Users/strut/.sdkman/candidates/springboot/1.5.3.RELEASE/lib/ext

Starting Eureka and the resulting exception:

Following directions from this question moved my $HOME/.m2 and tried starting Eureka. But that resulted in:

org.eclipse.aether.transfer.ArtifactTransferException: Could not transfer artifact org.bouncycastle:bcpkix-jdk15on:jar:1.55 from/to central (http://repo1.maven.org/maven2/): Bad file descriptor (connect failed).

Others seem to have this issue when running behind a proxy. But I am not running on a corporate network.
