You can also run PlantUML using the following command :
java -jar plantuml.jar file1 file2 file3
This will look for
file3. For each diagram, a
.png file will be created.
For processing a whole directory, you can use:
java -jar plantuml.jar "c:/directory1" "c:/directory2"
This command will search for
.java files of the
You can also use wildcards :
\), use a double
So to process any
.cpp files in all directories starting by dummy :
java -jar plantuml.jar "dummy*/*.cpp"
And to process any
.cpp files in all directories starting by dummy, and theirs subdirectories :
java -jar plantuml.jar "dummy*/**.cpp"
You can exlude some files from the process using the
java -jar plantuml.jar -x "**/common/**" -x "**/test/Test*" "dummy*/**/*.cpp"
You can specify an output directory for all images using the
java -jar plantuml.jar -o "c:/outputPng" "c:/directory2"
If you recurse into several directory, there is a slight difference if you provide an absolute or a relative path for this output directory.
You can also provide a configuration file which will be included before each diagram:
java -jar plantuml.jar -config "./config.cfg" dir1
After all preprocessing (includes etc), PlantUML saves the diagram's source code in the generated PNG Metadata in the form of encoded text.
-metadataoption. This means that the PNG is almost "editable": you can post it on a corporate wiki where you cannot install plugins, and someone in the future can update the diagram by getting the metadata, editing and re-uploading again. Also, the diagram is stand-alone.
-checkmetadataoption checks whether the target PNG has the same source and if there are no changes, doesn't regenerate the PNG, thus saving all processing time. This allows you to run PlantUML on a whole folder (or tree with the
Sounds like magic! No, merely clever engineering :-)
java -jar plantuml.jar -metadata diagram.png > diagram.puml
Unfortunately this option works only with local files. It doesn't work with
-pipe so you cannot fetch a URL with eg
curl and feed the PNG to PlantUML.
However, the Plantuml server has a similar feature, where it can get a PNG from a URL and extract its metadata.
When there are some errors in diagrams the command returns an error (-1) exit code. But even if some diagrams contain some errors, all diagrams are generated, which can be time consuming for large project.
You can use the
-failfast flag to change this behavior to stop diagram generations as soon as one error occurs. In that case, some diagrams will be generated, and some will not.
There is also a
-failfast2 flag that does a first checking pass. If some error is present, no diagram will be generated at all. In case of error,
-failfast2 runs even faster than
-failfast, which may be useful for huge project.
-pipe option, you can easily use PlantUML in your scripts.
With this option, a diagram description is received through standard input and the png file is generated to standard output. No file is written on the local file system.
cat somefile.puml | java -jar plantuml.jar -pipe > somefile.png
--pipemap option can be used to generate PNG map data (hyperlink rectangles) for use in HTML, eg:
cat somefile.puml | java -jar plantuml.jar -pipemap > somefile.map
The map file looks like this:
<map id="plantuml_map" name="plantuml_map">
<area shape="rect" id="id1" href="http://plantuml.com" title="http://plantuml.com"
You can have a help message by launching :
java -jar plantuml.jar -help
This will output:
