Florian Hockmann commented on TINKERPOP-1731:
---------------------------------------------
I finally found the cause for this: The {{Gremlin.Net.csproj.template}} was
encoded in UTF-8 and contained a [byte order mark
(BOM)|https://en.wikipedia.org/wiki/Byte_order_mark]. Apparently the Groovy
template engine has a problem with some special characters like this and
replaces them with {{\?\?\?}} during the docker build. That resulted in a
csproj file that had {{\?\?\?}} as the first characters right before the
license header comment which is of course not a valid XML file anymore.
I just pushed
[3bf128ae9f9d6f73675705a958b7b4102572eaaa|https://github.com/apache/tinkerpop/commit/3bf128ae9f9d6f73675705a958b7b4102572eaaa]
which simply removes the BOM bytes from the template file. This fixes the
build of Gremlin.Net with Docker.
Unfortunately the csproj file still contains some {{\?\?\?}}, e.g.,
{{TinkerPop™}} becomes {{TinkerPop\?\?\?}} and {{application’s}} becomes
{{application\?\?\?s}}. So we should probably find a way to tell the template
engine to always use UTF-8 as the encoding which should fix this problem
completely.

> Docker won't build the gremlin-dotnet stuff. I pulled out the {{.glv}} files
