Spring-boot resolves properties from a variety of sources , each source has a different priority.

One of the sources is environment variables, they have a higher priority than application.properties files.

Most UNIX shells set the environment variable pwd to be the current working directory, this is why it is replacing your configured value.

Simplest solution is to use a better more specific name for your property.
