Special characters in filenames are not escaped

[nudgegoonies]

Description

I have a Spring Project which produces files with a $ character in the middle of one filename. The $ sign is not escaped in the dockerfile and docker build tries variable substitution and cannot find the file.

How to reproduce

I have this file:

ServletInitializer$ApplicationContextHolder.class

What do you expect

$ character is escaped and file is copied to the image.

What happened instead

The $ character is not escaped in the dockerfile produced by the docker-maven-plugin. Docker cannot find the file because characters after the $ are interpreted as variable. In my case, the variable $ApplicationContextHolder does not exists and docker only looks for ServletInitializer.class

Software:

• docker version: 1.11.2
• docker-maven-plugin version: 0.4.10
• maven version: 3.3.9

Link to documentation where escaping is explained:
