Sculptor - M2 Plugins: Checksum Plugin should ignore non-existent directories

[Torsten Juergeleit]

The Checksum Maven Plugin insists of checking all directories specified in "checksumDirs".  If one of these directories isn't available (maybe because the project is created from scratch manually and consists initially only of "src/main/resources/") then the plugin aborts as shown in the following console log:

Here it would be helpful if the checksum silently ignores these non-existent folders and continues checking the other folders.

You can define set of directories by -D or by specifying parameter in
pom.xml. Parameter name is "checksumDirs" and default value is "src/
main/java,src/main/resources,src/test/java,src/test/resources".

Yes, one could redefine the set of checked directories in every single project which differs from the standard set of directories checked by the checksum plugin, e.g. one without test code.
Why not letting the checksum plugin skip non-existent directories? From my point of view the plugin should log a warning of skipping defined but non-existent directories but it must not abort the build.
