编译错误 server.go variable redeclared

[snipking]

基于 alpine 镜像构建 dog-tunnel 的 Docker 镜像，Dockerfile 如下

FROM alpine
RUN sed -i "s/http:\/\/dl-cdn.alpinelinux.org\/alpine/http:\/\/mirrors.aliyun.com\/alpine/g" /etc/apk/repositories && \
    apk update && \
    apk add git make go build-base && \
    go version && \
    mkdir /dog-tunnel-src && \
    cd /dog-tunnel-src && \
    export GOPATH="/dog-tunnel-src/" && \
    go get github.com/go-sql-driver/mysql && \
    go get github.com/klauspost/reedsolomon && \
    go get github.com/cznic/zappy && \
    go get github.com/vzex/dog-tunnel && \
    cd github.com/vzex/dog-tunnel/ && \
    git checkout origin/master -b udp && \
    make && \
    apk info && \
    apk del run-parts openssl lua5.2-libs lua5.2 ncurses-terminfo ncurses-widec-libs lua5.2-posix ca-certificates libssh2 curl expat pcre git go make build-base && \
    apk cache clean && \
    rm -rf /usr/lib/go && \
    cd .. && \
    rm -rf /dog-tunnel-src

go version go1.6.3 linux/amd64

报错如下

makefile看起来不对?
