问题
I'm using Maven to generate an archetype. I'm able to get the archetype to generate fine and the project template it generates works as expected. The only problem is in my shell scripts. Anything commented out in the script gets stripped leaving behind only commands. I've searched high and low and all I've been able to find was another user facing a similar issue with java comments. https://stackoverflow.com/questions/18797333/maven-archetype-generation-is-stripping-java-comments That question remains unanswered, so I figure I'll ask again. Does anyone know why Maven archetypes strip comments or how to prevent this from happening?
回答1:
Using the #set command itself to set a #hash variable equal to "#" worked, allowing me to maintain shell comments in scripts generated by the archetype. This can get relatively ugly when using 80 # symbols in a row in a header, but that's another matter...
回答2:
Maven uses Apache Velocity to perform substitutions/replacements when copying your archetype's template files to the project locations. The '#' character is used to begin directives, e.g. #set, in Velocity. My guess is that Velocity doesn't recognize your comment as a valid directive and silently deletes it during the replacement process.
Though I haven't verified this works - I would try escaping the comments with using a backslash (\) as defined in Velocity's user manual to solve the issue.

I also had a similar problem with hashes. On page http://johnjianfang.blogspot.com/2009/03/escape-properties-in-maven-archetypes.html I found answer.
Something like this works fine in my case:
#set($hash = '#')
${hash}
Output:
#
