My document includes several PDF files generated by PlantUML. These files are stored in different directories underneath the document directory. So far, I've created these files with a combination of shell scripts and Makefiles. Today I learned about latexmk's custom dependencies.
I've added the following to my .latexmkrc:
add_cus_dep('puml', 'pdf', 0, 'puml2pdf');
sub puml2pdf { system( "plantuml -Djava.awt.headless=true -charset UTF-8 -tpdf \"$_[0].puml\" \"$_[0].pdf\" "); }
Now latexmk should detect a missing PDF file on the first run and the custom dependency should kick in to run plantuml as defined. Unfortunately, it doesn't. lualatex fails with an error and the custom dependency is never written to the .fls file:
LaTeX Warning: File `signservice_isignaturecore.pdf' not found on input line 529.
! Package luatex.def Error: File `signservice_isignaturecore.pdf' not found: using draft setting.
See the luatex.def package documentation for explanation.
Type H <return> for immediate help.
...
l.529 ...sinf.opmon.ieventsenderforoperationmonitor}
Try typing <return> to proceed.
If that doesn't work, type X <return> to quit.
! Output loop---200 consecutive dead cycles.
\AP@clearpage ...e \m@ne {}\vbox {}\penalty -\@Mi
l.529 ...sinf.opmon.ieventsenderforoperationmonitor}
I've concluded that your \output is awry; it never does a
\shipout, so I'm shipping \box\outputbox out myself. Next time
increase \maxdeadcycles if you want me to be more patient!
The error probably results from the following construction in which I rotate the page and try to make sure that the float isn't placed too far way from text where it is referenced:
\afterpage{%
\clearpage% Flush earlier floats (otherwise order might not be correct)
\begin{landscape}% Landscape page
\centering % Center table
{
\begin{figure}[htbp]
\hypertarget{fig:mod.signservice.core.isignaturecore}{%
\includegraphics[width=0.75\columnwidth,keepaspectratio]{signservice_isignaturecore.pdf}
\caption{Klassenhierarchie für \java{IsignatureCore}}
\label{fig:mod.signservice.core.isignaturecore}}
\end{figure}
}
\end{landscape}
\clearpage% Flush page
}
Now two questions arise:
How can I convince
latexmkto write the missing dependency to the.flsfile despite the error?Is it correct that in order to make
latexmkrecognize the dependency in the first place, it must be started in-silentmode, otherwiselualatexhalts and requires user input. In this case, latexmk can't be used in a CI/CD environment without user interaction.
! Output loop---200 consecutive dead cycles. 2. The extract that lualatex prints from line 529 has nothing in common with the document code extract that you show. There is clearly a problem caused by something else in your document. You need to sort that out first: E.g., comment out the\includegraphicsline; I predict you will still get errors. Only worry about the custom dependency after the document is corrected.-interaction=batchmodetolatexmk. That is often better than just using the-silentoption if you are debugging problems. That's because the-silentoption also causeslatexmkto reduce the number of messages it writes, and these likely to be relevant to debugging.-timeoption tolatexmk. That causeslatexmkto give an end-of-run summary of what it ran (together with the timings).
