我已经使用以下指令创建了一个Docker映像：

FROM maven:3.5.0-jdk-8 as mavensrc   
FROM jenkins/ssh-agent:latest-jdk8   
COPY --from=mavensrc /usr/share/maven /usr/share/maven

ENV MAVEN_HOME /usr/share/maven
ENV USER_HOME_DIR="/home/jenkins"
ENV MAVEN_CONFIG "$USER_HOME_DIR/.m2"

RUN sed -i "s|PATH=|PATH=/usr/share/maven/bin:|" /etc/environment \   
       && apt-get update \
       && apt-get -y install binutils \
       && apt-get -y install rpm

这是一个jenkins代理，用于构建我的项目。所有工作正常，rpm生成，当安装时它按预期工作，但在构建日志中我发现了一个戳，我没有看到如果我在redhat7上构建它没有容器。
以下是日志：

执行的脚本似乎正确，例如/usr/lib/rpm/brp-strip包含：

#!/bin/sh
# If using normal root, avoid changing anything.
if [ -z "$RPM_BUILD_ROOT" ] || [ "$RPM_BUILD_ROOT" = "/" ]; then
        exit 0
fi

STRIP=${1:-strip}
NCPUS=${RPM_BUILD_NCPUS:-1}

case `uname -a` in
Darwin*) exit 0 ;;
*) ;;
esac

# Strip ELF binaries
find "$RPM_BUILD_ROOT" -type f \( -perm -0100 -or -perm -0010 -or -perm -0001 \) \! -regex "${RPM_BUILD_ROOT}/*usr/lib/debug.*" -print0 | \
    xargs -0 -r -P$NCPUS -n32 sh -c "file \"\$@\" | grep -v ' shared object,' | sed -n -e 's/^\(.*\):[  ]*ELF.*, not stripped.*/\1/p' | xargs -I\{\} $STRIP -g \{\}" ARG0

谁能告诉我为什么会有这些指纹？
我还尝试通过连接到容器来手动运行脚本，它在没有任何报告的情况下运行，所以可能它取决于maven执行的上下文。
