Start by running mvn clean package for swagger-codegen 3.0.7 and inspect the full Maven Surefire failure in the swagger-codegen core library, since the report includes only the reactor summary. Trace the failing test and its build configuration; done means the core library tests pass and the CLI, Maven plugin, and generator modules build successfully.
