Source code compilation failed with Docker and maven and settings.xml

Question

Getting source code compilation failuer error with below docker file.

FROM openjdk:8-jdk-alpine AS base
EXPOSE 8080:8080
FROM maven:3.6.0-ibmjava-8 AS build
WORKDIR /mywrkdir
COPY src src
COPY pom.xml .
COPY settings.xml .
RUN mvn -s settings.xml clean package
FROM base AS final
COPY --from=build /mywrkdir/target/xxx.jar xxx.jar
ENTRYPOINT ["java","-Dspring.profiles.active=someEnvironmentVariable","-Djava.security.egd=file:/dev/./urandom","-jar","xxx.jar"]

There is settings.xml with some specific profiles and repositories needed for application to build. For that purpose used maven command. But at below stage getting compilation error.

RUN mvn -s settings.xml clean package

Command used to build the test image is as below

az acr build --registry MyAcr --image testimg .

Error log when building docker file . Nothing is getting compiled RUN mvn stage from dockerfile:

Instead, try copying the entire directory, maybe you are missing some required file:

FROM openjdk:8-jdk-alpine AS base
EXPOSE 8080:8080
FROM maven:3.6.0-ibmjava-8 AS build
WORKDIR /mywrkdir
COPY ./ . # <-------- CHANGE MADE HERE
RUN mvn -s settings.xml clean package
FROM base AS final
COPY --from=build /mywrkdir/target/xxx.jar xxx.jar
ENTRYPOINT ["java","-Dspring.profiles.active=someEnvironmentVariable","-Djava.security.egd=file:/dev/./urandom","-jar","xxx.jar"]

Tried this, now that compilation error is gone. But getting **no main manifest attribute, in ./xx.jar** error message when trying to run via docker run command – bee Jan 29 '21 at 12:31
