Unable to start embedded Tomcat #11

Closed 7-- closed 6 years ago

7-- commented 6 years ago

I simply cloned the repo and ran "mvn spring-boot:run" on the "eureka-service".

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.5.RELEASE:run (default-cli) on project eureka-service: An exception occurred while running. null: InvocationTargetException: Unable to start web server; nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat: StandardEngine[Tomcat].StandardHost[localhost].TomcatEmbeddedContext[] failed to start -> [Help 1]

I tried changing the port number. I created a new Spring Starter Project with Eureka Server, same issue. I created a config server, and that runs embedded Tomcat with no issue.

Here's the full error, but it doesn't seem to say much. $ sudo mvn spring-boot:run [sudo] password for phil: WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by com.google.inject.internal.cglib.core.$ReflectUtils$1 (file:/usr/share/maven/lib/guice.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) WARNING: Please consider reporting this to the maintainers of com.google.inject.internal.cglib.core.$ReflectUtils$1 WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release [INFO] Scanning for projects...
