我想使用 docker 作为我试图在 AWS 上托管的 java spring boot 后端。但我似乎正在努力寻找以下问题的解决方案
=> ERROR [stage-1 3/3] COPY --from=build home/ec2-user/.mvn/wrapper/maven-wrapper.jar ./ 0.0s

ERROR: failed to solve: failed to compute cache key: failed to calculate checksum of ref 88fa4e79-193c-494c-9b78-a51635c02f26::sum3xp0gj6qesjumgreviomra: failed to walk /var/lib/docker/tmp/buildkit-mount2174057775/home/ec2-user/.mvn/wrapper: lstat /var/lib/docker/tmp/buildkit-mount2174057775/home/ec2-user/.mvn/wrapper: no such file or directory
这是我的 docker 文件
# Stage 1: Build Stage
FROM maven:3.8.4-openjdk-17 AS build
# Set the working directory in the container
WORKDIR /home/ec2-user
# Copy the Maven wrapper .jar file into the container
COPY mvnw ./
COPY mvnw.cmd ./
COPY .mvn ./
# Copy the project files and build the application
COPY pom.xml ./
COPY src/main ./src
RUN mvn clean install
# Stage 2: Runtime Stage
FROM openjdk:17
# Set the working directory in the container
WORKDIR /home/ec2-user

# Expose the port that the backend will run on
EXPOSE 3000

HEALTHCHECK --interval=30s --timeout=10s CMD curl --fail http://localhost:3000/health || exit 1
# Command to run your Java application
CMD ["java", "-jar", "maven-wrapper.jar"]
我尝试使用不同的命令运行它，并尝试从不同的文件夹运行复制命令。
docker build --no-cache --target build -t libarter-be-aws:build-stage .
This command works but later down the line it tells me this:

我尝试更改 pom 文件，但同样没有任何变化，无论我采取什么方法，我都遇到了两个不同的错误。
我只想构建它并让它运行，这正是我所需要的。
我也有同样的问题。你解决了吗？
