码头错误:找不到或加载主类Main.Main

Question

我编写了这个Dockerfile，它使一个项目可以运行，并且它也构建了，但是当我试图运行它时，它说“错误:找不到或者加载主类Main.Main”

Dockerfile：

RUN yum install -y java-1.8.0-openjdk.x86_64  java-1.8.0-openjdk- 
devel.x86_64 && yum clean all

COPY resources /home/resources
COPY elk_casino_server /home/elk_casino_server
RUN /usr/bin/javac /home/elk_casino_server/src/Main/Main.java
RUN jar vcmf /home/elk_casino_server/src/META-INF/MANIFEST.MF 
/home/elk_casino_server/src/server.jar
/home/elk_casino_server/src/Main/Main.class 
/home/elk_casino_server/src/config.properties
CMD ["java","-jar","/home/elk_casino_server/src/server.jar"]

Docker COPY命令接受path作为第二个参数。试着改变你的Dockerfile

Dockerfile

COPY resources /home/
COPY elk_casino_server /home/
