# The C4-PlantUML docs say that it suffices to run plantuml with the
|
|
# -DRELATIVE_INCLUDE="..." arg to make plantuml find the C4 templates
|
|
# when included like "!include C4_Container.puml".
|
|
# Unfortunately, this is not sufficient in practise, when the path is not ".".
|
|
# What helps is setting -Dplantuml.include.path="..." *before* the jar
|
|
# parameter.
|
|
# The -DRELATIVE_INCLUDE param then *still* needs to be set (*after* the jar
|
|
# argument), because the C4 template vars check for existence of this variable
|
|
# and if it is not set, reference paths in the internet.
