Docker supports multiple src resources for the ADD command: https://docs.docker.com/reference/builder/#add

In docker-java however, the ADD_OR_COPY_PATTERN in DockerfileStatement.Add prevents this from working.

I have a Dockerfile which contains a line like:

ADD src1 src2 /dest/

The Dockerfile builds without a problem when run directly with docker build. However, when I try to build the same Dockerfile using the Docker plugin on Jenkins, I get this error:

{"stream":"Step 7 : ADD src1 src2 /dest/\n"}
{"errorDetail":{"message":"src1: no such file or directory"},"error":"src1: no such file or directory"}

BTW, the Pattern may also have a problem with src or dest resources with spaces in their path. This is also supported by Docker, as long as the paths are surrounded by double quotes.
