Thanks for the feedback.

It should be fixed in last beta http://beta.plantuml.net/plantuml.jar

Confirmed that "No diagram found" is not output as expected.
Thank you for your quick response.

Hi,

"No diagram found" was output even with the "-checkonly" option.
It did not output what was the result of the check.
If there is no problem, do not output anything?

Right !

This has been solved in yet another beta http://beta.plantuml.net/plantuml.jar

Thanks for your test and tell us if you find other issues!

Hi!
The "-pattern" option also outputs "No diagram found".
It is unnecessary :-p)

Hi dears,

have the same issue.

I'm trying to use it as a subprocess in python, but I got below error:

b'Warning: no image in test.puml\n'
b'No diagram found\n'

    command = 'java -jar plantuml.jar -pattern ' + output_puml_file
    print('Wrote PUML output to ' + output_puml_file)
    child = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
