We are calling ModelGraphGenerator from Gradle Build Script.
The resulting call looks like this:
Starting process ‘command ‘C:\Program Files\Zulu\zulu-21\bin\java.exe’’. Working directory: C:-Projects-\kdialog-sii-au\kdialog-sii-au-models Command: C:\Program Files\Zulu\zulu-21\bin\java.exe -Dfile.encoding=UTF-8 -Duser.country=DE -Duser.language=de -Duser.variant -cp C:\gradle.tmp\gradle-javaexec-classpath17948417590495009953.jar com.mgmtp.a12.dataservices.tooling.modelgraph.ModelGraphGenerator –output=C:-Projects-\kdialog-sii-au\kdialog-sii-au-models\build\models\modelGraph.json C:-Projects-\kdialog-sii-au\kdialog-sii-au-models\models\auftragsuebersicht-document.json,C:-Projects-\kdialog-sii-au\kdialog-sii-au-models\models\auftragsuebersicht-mini-overview.json,C:-Projects-\kdialog-sii-au\kdialog-sii-au-models\models\auftragsuebersicht-overview.json,C:-Projects-\kdialog-sii-au\kdialog-sii-au-models\models\auftragsuebersicht-sl-overview.json
This results in the following error:

The parameters given for the model files are geting an additional path in front (maybe working directory) which leads to an error.
I tried also with separate parameters for each file instead of comma separated concatenated string.
Am I doing something wrong? Is there a workaround?
So it should work if you prepend file:/// to all inputs. And I didn’t know comma separated paths are possible, we always just specified the folder and it picked up all models.
