Was stumped today by the adhoc_tool that I am creating. I want to use a python script that takes an xml file and a few template files as input, and generates some language bindings as an output. Focusing first on python-in and python-out, here's what I have so far. Repo layout:

├── interface
│   ├── BUILD
│   ├── interface.dtd
│   ├── interface.xml
│   └── xmlconvert.py
└── pants.toml

And the BUILD file:

python_source(
    name="xml_convert_py",
    source="xmlconvert.py",
)

files(name="interface_deps", sources=["interface.xml"])

adhoc_tool(
    name="xmlconvert",
    runnable=":xml_convert_py",
    execution_dependencies=["interface.xml:interface_deps"],
    output_files=[<tbd, need to fix the FileNotFoundError first>]
)

Running

pants run interface:xml_convert_py

, I get a FileNotFoundError. The pants sandbox does not receive the interface.xml file. How can I solve this?

You may need to use

resources

instead of

files

for the

interface.xml

file.

> You may need to use
