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： [2021-11-10 18:54:23] [INFO] Packaging webapp [2021-11-10 18:54:23] [INFO] Assembling webapp [nr-engine] in [/nr-engine/target/nr-engine] [2021-11-10 18:54:23] [INFO] Processing war project [2021-11-10 18:54:23] [INFO] Copying webapp webResources [/nr-engine/src/main/webapp] to [/nr-engine/target/nr-engine] [2021-11-10 18:54:23] [INFO] Copying webapp resources [/nr-engine/src/main/webapp] [2021-11-10 18:54:23] [INFO] Building war: /nr-engine/target/nr-engine.war [2021-11-10 18:54:23] [INFO] ------------------------------------------------------------------------ [2021-11-10 18:54:23] [INFO] BUILD SUCCESS [2021-11-10 18:54:23] [INFO] ------------------------------------------------------------------------ [2021-11-10 18:54:23] [INFO] Total time:  01:12 min [2021-11-10 18:54:23] [INFO] Finished at: 2021-11-10T10:54:23Z 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 .

如题，码云上的mavn项目想使用云托管部署 如果我在Dockerfile中引用官方mavn镜像，那tomcat该怎么弄呢 是需要再弄个tomcat镜像、还是可以搞到一个镜像里面？ 如果可以一个镜像的话，Dockerfile怎么写
