java.lang.ClassNotFoundException: com.example.StreamLambdaHandler

See original GitHub issue

Description:

When executing the spring-boot example:

mvn archetype:generate -DgroupId=my.service -DartifactId=my-service -Dversion=1.0-SNAPSHOT \
       -DarchetypeGroupId=com.amazonaws.serverless.archetypes \
       -DarchetypeArtifactId=aws-serverless-springboot-archetype \
       -DarchetypeVersion=1.1

And running the project (via. sam local start-api --template sam.yaml --debug) results in the following error:

START RequestId: 9e5a7678-5dda-49a2-b244-1337d775ffa2 Version: $LATEST
java.lang.ClassNotFoundException: com.example.StreamLambdaHandler
	at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
	at java.lang.Class.forName0(Native Method)
	at java.lang.Class.forName(Class.java:348)

This seems to be an issue specifically with Ubuntu sam/docker (Possibly also with ubuntu version 18.04 specifically). Running the same sam-cli 0.3.0 and docker 18.03.1-ce on OSX works correctly and a response is returned as expected.

+1 setup:

Ubuntu: 16.0.4 Docker: 18.03.1-ce Sam: 0.3.0

It works for JS and fails for Java. Rolling back onto Sam 0.2.11 works for Java.

+1 here too on:

Linux Mint 18.1 Cinnamon 64-bit Sam 0.3.0 Docker 18.03.1-ce

This is really slowing down our Java development!

Seems to work okay for JavaScript though
