Local build is working but when using a dockerised version of the CLI, snyk test fails

This is usually caused by some of the dependencies relying on a compiled artifact which is available locally but not on the central repository.

Solution
Make sure to mount the local repository into the Docker image so that the local maven can leverage the local artifact (side benefit, it wont download anything already present, making the test faster)
Example of such command

docker run -it -e "SNYK_TOKEN=YOUR_TOKEN_HERE" -e "MONITOR=true" -v "/Users/pstember/Git/java-goof:/project" -v "/Users/pstember/.m2:/root/.m2" -v "/Users/pstember/.ivy2:/root/.ivy2" snyk/snyk-cli:maven-3.6.1 test --org=second-org --file=todolist-web-common/pom.xml

where the important bit is -v "/Users/USERNAME/.m2:/root/.m2" -v "/Users/USERNAME/.ivy2:/root/.ivy2"
