Fill mojo file set with cli argument

Question

I like to generate images from .puml files in a maven project.

What I don't like about the archive is the tight binding between the project and the library that generates the images. Therefore, I like to use this build command:

mvn com.github.jeluard:plantuml-maven-plugin:1.2:generate \
  -Dplantuml.outputDirectory=target \
  -Dplantuml.sourceFiles={*.puml}

So the third line fills sourceFiles-class-variable

Unfortunately, the syntax {*.puml}seems to be wrong:

[INFO] --- plantuml-maven-plugin:1.2:generate (default-cli) @ test ---

Answer 1

It is better to specify the source set of files through pom.xml and specify this file through -f: mvn -f mypom.xml.

See jeluard / maven-plantuml-plugin Usage :
