[minor] path to dot binary hardcoded

[Eothred]

Tried to compile this on my system, and I encountered one issue. In the pom file the path to dot is hardcoded as <dotExecutable>/usr/local/bin/dot</dotExecutable>. Removing this line solved it for me. I imagine anyone that has set up dot in /usr/local/bin also would have that in their path, deeming this unecessary?

Other than that it compiled fine, using openjdk-11 and maven 3.6.0 on an arch linux based system. I noticed that one dot file and a few png's were marked as updated in the repository, which is perhaps ideally not necessary as a default action

Hello Yngve,

it was a leftover. The correct line now is:

<dotExecutable>${dot.executable}</dotExecutable>

It uses another variable defined few lines above:

<!-- Auxiliary programs -->
<dot.executable>/usr/local/bin/dot</dot.executable>

I still need to understand how to set those properties in settings.xml. The value is needed for the fixup.sh. I'ver tried to use $(which dot) but it didn't work. I need more help from unix experst. I set this as a bug to be fixed.

Moreover, I also need to understand how, from maven, invoke a fixup.bat file on a Windows system.

Sorry but thinking to it twice, it is not a bug.
You indeed should not build the code, but use the library from Maven Central (or Maven snapshot repository).
Anyway, I'll keep the issue open to see if I can improve it.
