Using an environment variable to define a path when using the Docker executor

Overview

In some cases you may need to use an environment variable when specifying a path. For example: source ${CIRCLE_WORKING_DIRECTORY}/script.sh which will expand to the string literal ${CIRCLE_WORKING_DIRECTORY}/script.sh when using the Docker executor.

Resolution

    1. You can use the pwd command. Example: source $(PWD)/script.sh. 
    2. You can use the eval command. Example:  source $(eval echo ${CIRCLE_WORKING_DIRECTORY}/script.sh)
    3. Add the following run step to your build: 
 - run:  
     name: "Fix CIRCLE_WORKING_DIRECTORY"  
     command: echo 'CIRCLE_WORKING_DIRECTORY="${CIRCLE_WORKING_DIRECTORY/#\~/$HOME}"' >> $BASH_ENV
