docker：错误：无法访问 jarfile /app.jar

Question

Docker文件：

FROM adoptopenjdk/openjdk11:latest
VOLUME /tmp
COPY ./entrypoint.sh /app/entrypoint.sh
WORKDIR /app
RUN chmod +x /app
ENTRYPOINT ["/app/entrypoint.sh"]
CMD [ "java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar" ]

入口点.sh：

#!/bin/bash

./mvnw clean package -DskipTests
cp target/bantads-cliente-*.jar /app.jar
eval "$@"

我已经修改了mvnw的权限，Dockerfile和entrypoint.sh都在工作目录下同级
