[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.0:test (default-test) on project swagger-codegen: There are test failures.

So I can't to install packages and run code generator.

Start by rerunning ./run-in-docker.sh mvn package and capture the complete maven-surefire-plugin failure output, since the report only includes the reactor summary. Inspect the Docker build and Maven test setup to identify why the swagger-codegen core library tests fail; done means the package builds successfully and the tests pass.
