无法使用 docker build 运行 gradle 包装器

Question

我有这个小构建：

FROM eclipse-temurin:17-jdk as build-java
COPY java-project /root/project
WORKDIR /root/project
RUN chmod +x ./gradlew
RUN ls
RUN ./gradlew ...

#9 [build-build-java 5/6] RUN ls
#9 sha256:2d05b1e31ea4eaa8a9343b4f48fadcf7351b9d55dcc9c27e572d7bb32c4d723c
#9 0.194 build
#9 0.194 build.gradle
#9 0.194 docker-compose.yml
#9 0.194 gradle
#9 0.194 gradlew
#9 0.194 gradlew.bat
#9 0.194 HELP.md
#9 0.194 lombok.config
#9 0.194 settings.gradle
#9 0.194 src
#9 DONE 0.2s

#10 [build-build-java 6/6] RUN ./gradlew ...
#10 sha256:62cb4a1a6288008f3faccc3504e63ef87d30c3d7fde904a0576ffcf571e9b310
#10 0.310 /bin/sh: 1: ./gradlew: not found
#10 ERROR: executor failed running [/bin/sh -c ./gradlew ...]: exit code: 127

我已经被困在这个问题上有一段时间了。

我尝试FROM gradle先使用，然后再使用gradle ...，但随后出现此文件安装错误：

Answer 1

我在Windows环境下也遇到了同样的问题。正如@thokuest指出的，这是根据\rbash 脚本中的回车符 ( ) 行结尾发生的。但是您应该考虑到，当您将IntelliJ 中的行结尾更改为from时，容器中的文件不会相应更改，而是从您之前的命令缓存。所以你应该运行这个命令：LFCLRFgradlewdocker build .

docker build --no-cache .

或者：

docker build --no-cache --progress=plain .如果你想看到完整的输出。

Answer 2

/bin/sh: 1: ./gradlew: not found\r通常是由bash 脚本中的回车符 ( ) 行结尾引起的。删除回车符很可能会解决该问题。
