在Windows上为Linux CentOS构建RPM

Question

我正在尝试使用Windows上的RPM Maven插件构建RPM，以便在Linux机器上部署。

正在构建RPM的机器的操作系统：Windows 7 Enterprise，Cygwin 2.5.1

安装 RPM 的虚拟机操作系统：CentOS 7

我已经运行了 mvn 干净安装命令并且构建成功。

[INFO] Finished at: Sun Apr 24 21:08:51 BST 2016
[INFO] Final Memory: 10M/157M

但是，当我将其搜索到服务器并运行yum install -y Core1337-1.0-1.noarch.rpm

我收到以下错误：

Transaction check error:   package Core1337-1.0-1.noarch is
 intended for a different operating system

如何配置插件以使用 linux 标头构建 RPM？任何帮助都非常感谢！

Answer 1

在Windows上构建RPMS以部署在Linux机器上可能很复杂。我建议在将部署它的同一操作系统上构建 RPMS。

Answer 2

直接使用 rpmbuild 命令，可以使用 --target 选项覆盖目标操作系统。

rpmbuild -bb hello.spec --target x86_64-linux

要验证：

rpm -qp --qf '%{os}n' hello-1-1.x86_64.rpm 
linux
