Hello,

What version of Jmix are you using? How do you deploy an application to production?

Hello,

I found a solution to your problem.

The error occurs because JasperReport is trying to compile the report template, but javac is not available to it. To do this, you need to create a docker image with JDK.

For example, Dockerfile:

FROM amazoncorretto:11-alpine-jdk

WORKDIR /app

COPY build/libs/jmix-reports-v1-0.0.1-SNAPSHOT.jar /app

RUN apk add --no-cache msttcorefonts-installer fontconfig
RUN update-ms-fonts

ENTRYPOINT ["java", "-jar", "/app/jmix-reports-v1-0.0.1-SNAPSHOT.jar"]

When building an image, it is also important to install fonts.
And in the dependencies you need to add a dependency on jasperreports:

implementation 'net.sf.jasperreports:jasperreports:6.20.0'

Regards,
Nikita
