Is there a way to configure Java heap size for the docker container?

When I run openapi-generator-cli on a large OpenAPI file with useDocker, I get the following error when generating Java code:

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

Other languages work fine, and I suspect I just need to give the Java heap some more memory. However, when I look at https://github.com/OpenAPITools/openapi-generator-cli/blob/f3f431db8080a57f788adedd09e2e1aa52ee07b3/apps/generator-cli/src/app/services/pass-through.service.ts#L119-L124, it doesn't appear there's any way to pass in JAVA_OPTS="-Xmx4g" or similar.

Am I missing something? Is there any way to set the max Java heap size?

Inizia da apps/generator-cli/src/app/services/pass-through.service.ts, intorno alle righe 119-124, e segui il modo in cui useDocker avvia il generatore. Verifica se è possibile passare opzioni Java; il lavoro è completato quando è stata documentata o resa disponibile un’impostazione per la dimensione dell’heap e verificata la generazione di un progetto Java di grandi dimensioni senza l’errore segnalato.
