使用 sbt native packager 为 scala play app 创建 rpm

Question

我正在使用 sbt native packager (https://github.com/sbt/sbt-native-packager) 为 scala play 应用程序创建 rpm。我按照说明运行命令sbt rpm:packageBin。但是，它构建了.jar 文件，这是 rpm 构建吗？我认为 rpm 构建应该是 .rpm 扩展名？

我确实收到了错误，但我仍然可以看到 .jar 文件

Answer 1

Play Framework 需要一些额外的 rpm 设置。这记录在here in the Play Documentation。 为简单起见，我在此处复制相关部分：

最低 RPM 设置

将以下设置添加到您的构建中：

lazy val root = (project in file("."))
  .enablePlugins(PlayScala)

maintainer in Linux := "First Lastname <first.last@example.com>"
packageSummary in Linux := "My custom package summary"
packageDescription := "My longer package description"
rpmRelease := "1"
rpmVendor := "example.com"
rpmUrl := Some("http://github.com/example/server")
rpmLicense := Some("Apache v2")

然后构建你的包：

[my-first-app] $ rpm:packageBin

最后你应该在 target/rpm/RPMS/noarch/ -folder（或类似的东西）下拥有projectname-projectversion.rpm。

Answer 2

在您的 cmets 之后，我会说您需要在 build.sbt 文件中添加更多信息。

您的项目应包含有关 rpm 的数据。您可以使用很多设置here，但最起码​​的是将 rpmVendor 添加到您的 build.sbt 中，如下所示：

rpmVendor := "VendorName"

如果您需要示例，请查看 Github 上的一些示例。
