It is not possible to activate all PlantUML elements with "ENABLE_ALL_PLANT_ELEMENTS". New PlantUML server versions produce an error.

[kirchsth]

The "Sample with PlantUML elements" sample in the LayoutOptions.md section is not working anymore (ex. PlantUML version 1.2025.4beta3).

If "!ENABLE_ALL_PLANT_ELEMENTS = 1" is set then it produces an error like below:

If the options is not activated then it works without any problem ("only" the style is not correct):

The problem is the changed "\n", "%newline()" handling in the new PlantUML versions.

[kirchsth]

The problem is that the "style" supports no %newline() anymore ("skinparam" are fixed in the meantime and works again).
Eg. following sample works with an older version (ex. v1.2024.5) but not with current version (ex. v1.2025.3beta4).
The sample contains a skinparam and a style section but only the styles are the problematic one.

@startuml
!ENABLE_ALL_PLANT_ELEMENTS = 1

!function $nl()
  ' workaround
  ' !return %breakline()
  !return %newline()
!endfunction

!function $elementTagSkinparams($element, $tagStereo, $fontColor)
  !$elementSkin = "skinparam " + $element + "<<" + $tagStereo + ">> {" + %newline()
  !if ($fontColor != "")
    !$elementSkin = $elementSkin + "    StereotypeFontColor " + $fontColor + %newline()
    !$elementSkin = $elementSkin + "    FontColor " + $fontColor + %newline()
  !endif
  !$elementSkin = $elementSkin + "}" + %newline()
  !return $elementSkin
!endfunction

' label colors cannot be set via skinparam use style
!function $labelElementTagSkinparams($tagStereo, $bgColor)
    !$tagSkin = $nl() + "<style>" + $nl()
    ' componentDiagram {
    !$tagSkin = $tagSkin + "  label {" + $nl()
    !$tagSkin = $tagSkin + "    ." + $tagStereo + " {" + $nl()
    !$tagSkin = $tagSkin + "      StereotypeFontColor " + $bgColor + $nl()
    !$tagSkin = $tagSkin + "      Fontcolor " + $bgColor + $nl()
    !$tagSkin = $tagSkin + "    }" + $nl()
    !$tagSkin = $tagSkin + "  }" + $nl()
    ' }
    !$tagSkin = $tagSkin + "</style>" + $nl()
  !return $tagSkin
!endfunction

!unquoted procedure $defineSkinparams($tagStereo, $bgColor, $fontColor)
  ' skinparam works based on updated server implementation
  !$tagSkin = $elementTagSkinparams("rectangle", $tagStereo, $fontColor)
  !$tagSkin = $tagSkin + $elementTagSkinparams("package", $tagStereo, $fontColor)

  ' style does not work, %newline() is not supported anymore
  !$tagSkin = $tagSkin + $labelElementTagSkinparams($tagStereo, $bgColor)
$tagSkin
!endprocedure

$defineSkinparams("red", white, red)
$defineSkinparams("blueboundary", white, blue)
$defineSkinparams("bluelabel", blue, white)

[C]

rectangle r <<red>> {
}

label "LABEL" as l <<bluelabel>>

package p <<blueboundary>> {
}

@enduml

If I replace the %newline() in the styles with the new %breakline() the it works with the new PlantUML version too.

!function $nl()
  ' workaround
  !return %breakline()
  ' !return %newline()
!endfunction

I reported in forum an issue for that.

[arnaudroques]

Thank you for the report.

I'm a bit confused about the following stack trace entries:

        at net.sourceforge.plantuml.command.CommandSkinParamMultilines.execute(CommandSkinParamMultilines.java:112)
        at net.sourceforge.plantuml.command.CommandSkinParamJaws.executeArg(CommandSkinParamJaws.java:114)

The reason is that there is no line 112 in CommandSkinParamMultilines.java and no line 114 in CommandSkinParamJaws.java.
Which PlantUML jar file are you using?

Also, I cannot reproduce the crash, the following example works fine on my side:

Hi @arnaudroques,

thank you for your fast response (and sorry for my delay).

If I try to open following link then I cannot display it on the server (using %newline())

If I replace it with %breakline() and display the %version() then you see it is a 1.1025.3beta5 server

I tried it locally on my windows version with the MIT version "plantuml-mit-SNAPSHOT-v1.2025.3beta5.jar" (from 30.3.) too, and it was not working.

I attached my puml and the console log too:

TODO.puml.txt (please remove txt extension)
TODO.notworking.log

I tried it with ".\plantuml-mit-1.2025.2.jar " too, same exception.

============

Now I tried a simpler sample, I think it shows the problem in the UI with the %newline() (but without exception):

newlineNotWorking.puml.txt

>java -jar .\plantuml-mit-SNAPSHOT-v1.2025.3beta5.jar .\newlineNotWorking.puml
Error line 24 in file: .\newlineNotWorking.puml
Some diagram description contains errors

=============

With this script I can reproduce it with %newline() and %breakline(). For me it looks like that the problem is that 2 variables are combined (tested it with ex. .\plantuml-mit-1.2025.2.jar produces the same state exception; only changed lines in SourceFileReaderAbstract class).

@startuml

!unquoted procedure $defineSkinparams($tagStereo, $bgColor, $fontColor)
  !$elementSkin = "skinparam " + $element + "<<" + $tagStereo + ">> {" + %newline()
  !$elementSkin = $elementSkin + "}" + %newline()
' none of both is working
!$defs = $elementSkin + %newline()
'!$defs = $elementSkin + %breakline()
$defs
!endprocedure

$defineSkinparams("bluelabel", blue, white)

label "LABEL" as l <<bluelabel>>

@enduml

Or you can see the illegal state exception on server too

No problem, I have answered on the forum.
