如题，mvn package之后，想把war拷贝到tomcat，一直失败。。。

从日志看，打包是成功的：

但是，拷贝不成功：

[2021-11-10 18:54:30] Step 13/15 : COPY ./target/nr-engine.war $CATALINA_HOME/webapps/nr-engine.war
[2021-11-10 18:54:30] COPY failed: stat /var/lib/docker/tmp/docker-builder408548833/target/nr-engine.war: no such file or directory
script returned exit code 1

把拷贝的源路径改成绝对路径“/nr-engine/target/nr-engine.war”也一样。。。

后来在Dockerfile中加了命令 ls，发现目录确实是存在的；

后来又加命令 ls -l target ，发现没权限！应该是这个原因，才会导致拷贝（ADD 和 COPY 都试过）失败。

有谁碰到过吗？这是什么情况？

以下是Dockerfile：

FROM maven:3.8.3-openjdk-8

# 指定Maven环境变量(这里由于使用官方镜像，路径按照官方镜像Dockerfile中的来，否则会找不到mvn)
ENV MAVEN_HOME /usr/share/maven
ENV PATH $MAVEN_HOME/bin:$PATH

WORKDIR /nr-engine
COPY ./nr-engine/pom.xml .
COPY ./nr-engine/src ./src
COPY ./nr-engine/setting.xml ./setting.xml

RUN rm -rf target && mkdir -m +r "target"
RUN ${MAVEN_HOME}/bin/mvn -U clean package --settings /nr-engine/setting.xml -DskipTests

# 添加tomcat容器到镜像中
FROM tomcat:jre8-openjdk

# 保险起见，按照tomcat官方镜像配置环境变量
ENV CATALINA_HOME /usr/local/tomcat
ENV PATH $CATALINA_HOME/bin:$PATH

# 将war包添加进tomcat
# 
# ADD nr-engine.war $CATALINA_HOME/webapps/
COPY ./target/nr-engine.war $CATALINA_HOME/webapps/nr-engine.war

# 指定端口
EXPOSE 8080
# CMD ["catalina.sh", "run"]
RUN $CATALINA_HOME/bin/catalina.sh
