How can I add process parameters using sbt-native-packager? - sbt

Question

How can I add process parameters using sbt-native-packager configuration? I want to add the options for redirect process stderr to file? To have the result like that:
sudo -u app bash -c "app >>/var/log/app/stderr.log 2>&1"
I use sbt-native-packager 1.2.0-M5 for build deb package with JavaServerAppPackaging, JDebPackaging, SystemdPlugin, UpstartPlugin the exception in logs, only in stderr. Also I must delete app pid manually after crash and if it exists, then I have error in stderr.
My plugins.sbt:
resolvers += Resolver.bintrayRepo("sbt", "sbt-plugin-releases")
// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.5.8-netty-4.1")
addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.2.0-M5")
addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.8.2")
addSbtPlugin("com.lightbend.sbt" % "sbt-javaagent" % "0.1.1")
libraryDependencies += "org.vafer" % "jdeb" % "1.3" artifacts (Artifact("jdeb", "jar", "jar"))
my build.sbt:

import com.typesafe.sbt.packager.archetypes.systemloader._
// UpstartPlugin for ubuntu 14.04, SystemdPlugin for ubuntu 16.04
enablePlugins(JavaServerAppPackaging, JDebPackaging, SystemdPlugin, UpstartPlugin)
requiredStartFacilities := Some("datadog-agent.service, systemd-journald.service, postgresql.service")
javaAgents += "org.mortbay.jetty.alpn" % "jetty-alpn-agent" % "2.0.4" % "dist"
ps I found a workaround, in ubuntu 16.04 I can use journald to collect all the logs in the system.

Answer 1

Thanks for updating the question with all relevant information. There are a couple of things here.
Only one Systemloader plugin
You enable SystemdPlugin and UpstartPlugin. If it works, it only works by accident. No version of native-packager was designed to support multiple systemloader for a single package type in a single build module.
The solution is to create sub modules with the relevant systemloader enabled.
Logging to stderr
You are right regarding systemd. It provides facilities to capture the log output of your process. If you like you can add your findings to the native-packager documentation ( there is a systemd plugin section ).
The upstart support in native-packager is rather simple. There weren't a lot of requeset as Ubuntu is switching to systemd and you can always fallback to systemv. Which brings me to the solution to your problem.
You can use the SystemVPlugin, which supports a daemon_log_file. The systemv documentation provides you with the necessary details.
cheers,
