Warning while building docs containing plantuml diagram

[Ashyglim]

Thank you for developing this plugin!

I met a problem where no diagrams are correctly created while building docs using sphinx.
The log gave the warning as the following:
WARNING: plantuml command 'plantuml' cannot be run

The build succeeded but no diagram were created.
I have already setup a batch file which contains running script of plantuml.jar and set the path to the batch file as an environment variable. But this problem is still there.

The full log is as the following:

Windows batch file runs quite differently than a normal command.
You'll probably need to specify plantuml = ['cmd.exe', '/c', path_to_batch_file],
or simply embed the batchfile content into plantuml = [...].

Thank you for the reply!
In the usage I saw it could be done in Unix to specify plantuml command that

puts wrapper script in your PATH

I was wondering if there is a way to do this in windows too.

[yuja]

could be done in Unix to specify plantuml

Yep, Unix shell scripts can work exactly in the same semantics as compiled executables.

if there is a way to do this in windows

I'm not a Windows nor Java person, but maybe you can build an exe wrapper?

Thank you!

The problem has been solved by modifying the setup function in plantuml.py
Not a clean solution but it got to the goal without modifying conf.py, which is a hard requirement here.

My fix on Windows 10:

• In make.bat: set SOURCEDIR=.
• Add plantuml.bat next to make.bat: java -jar C:\Users\Cees\AppData\Roaming\JetBrains\PyCharm2020.3\plugins\plantuml4idea\lib\plantuml.1.2021.0.jar %*

install plantuml from shell.

demonstrated to work on CI/CD of my university class docs, Linux environment (also locally on MacOS).

with sphinx extensions installed (pip) and configured (conf) it runs and renders correctly.
