build failed: Conversion = '%'

[aporo69]

Hi,

I tried to setup a minimalistic maven projecct to try your plugin and I am getting a build failure with the following message:

[INFO] DOCKER> Selecting previously unselected package init-system-helpers.
(Reading database ...
[INFO] ------------------------------------------------------------------------

The thing is that error occurs only at the first time I build a container which means that once docker uses its cache, the error doesn't show up.

Here's what I get with a mvn -X:

I am using Maven 3.3.3 with an OpenJDK 1.8.

Here is a sample project to reproduce the issue: [https://github.com/aporo69/docker-maven-plugin-issue-457]

Thank you for your help and keep up with the good job :)

Thanks a lot for reporting this !

It's an regression introduced when formatting info messages has been added. this is fixed in the next relase.
