0.8.0: JDebPackaging tries to create symlink using 'ln' on windows

[aparamonov]

I receive following error:

"ln": creating symbolic link `guide-menu-web' to `/usr/share/guide-menu-web/bin/
guide-menu-web': No such file or directory

If I add 'debianExplodedPackage in Debian := (target in Debian).value' to build.sbt, the error disappears.

Can you create a small sample project to reproduce this?

[aparamonov]

Please take a look at repository https://github.com/aparamonov/sbt-native-packager-467-issue

[stillyetanothergithubuser]

I get the same error. The issue appears to be that the name of the link it's trying to create is a *nix fs style path. ("Failed to symlink /usr/share/emptyplay23/bin/emptyplay23 to C:\src12\emptyplay23\target\emptyplay23-.1\usr\bin\emptyplay23")

Digging into the code to see if I can see why. Here's the stacktrace though. (Using sbt-native-package 0.8.0 bundled with Play 2.3.7. I created an empty play-scala project added debian package info to build file and tried to create a debian package.)

Sorry for realizing what is actually happening so late.
Native packager first goal is to make the packaging work on the platform
where it will execute afterwards (debian on debian machines, rpm on red hat machines,
exe on windows machines, etc..)

1. You are trying to build a debian package on windows, so there's no guarantee it will work
2. ln is only the first problem, you need dpkg tools installed as well.

BUT, there is a jdeb implementation, which can be activated with (in 0.8.0)

packageBin in Debian <<= debianJDebPackaging in Debian

You can also find this in the DebianPlugin docs

[aparamonov]

The issue is appeared when I use jdeb implementation (as you can see in the project by link above).
So the only problem with ln tool. Please, reopen the issue and get rid of usage of that tool on Windows platform.

[aparamonov]

Debian package is created when I run 'sbt debian:packageBin' on that project on Mac OS.

[muuki88]

I just had time to take a quick look at the example project. First of all you must not add the packageArchetype.java_server settings again in your build.sbt. This will override all play settings. Does this help?
