Plugin has OOM exception when building Docker image

[sgolubovic-interventure]

I have a simple example of a Spring Boot application which I'm trying to Dockerize:

• Spring Boot 3.1.5
• Java 17
• Kotlin 1.8.22
• ktlint Maven plugin 1.16.0

---

In Dockerfile I try to build the JAR using ./mvnw package command in first step, and use produced JAR in the second step:

FROM eclipse-temurin:17-jdk-jammy AS builder

COPY mvnw .
COPY .mvn .mvn
COPY pom.xml .
COPY src src

RUN ./mvnw package -DskipTests -e
# ------------------------------------------------------
FROM amazoncorretto:17-alpine-jdk

WORKDIR /apps

COPY --from=builder /target/demo-*.jar /apps/app.jar

USER nobody
CMD ["java", "-jar", "app.jar"]

When I try to build the image using docker image build -t demo:1 ., at some point I get:

If I comment out the plugin, everything works fine. Also, if I try to build it locally with ./mvnw clean package -Dmaven.repo.local=.m2/repo it works fine as well.

Does anyone have an idea what could be the issue?
