Here, @ system_envs is the previously analyzed env. exported_system_environment_variables, and @ user_envs is env. exported_user_environment_variables. There are two other scripts: export_buildpack_env_variables_script and start_script. The code for the export_buildpack_env_variables_script script is as follows, which means to execute all sh scripts in a certain path:
