failed to create symbolic link

[avdv]

I'm using the java_server archetype.

The debian:packageBin task creates a symlink in /usr/bin pointing to the final target file.

This link is invalid when created in the staging directory and becomes valid once installed on the system.

After having run the debian:packageBin task once, it fails on subsequent calls with

ln: failed to create symbolic link `repo-service': File exists

The check at https://github.com/sbt/sbt-native-packager/blob/master/src/main/scala/com/typesafe/sbt/packager/linux/LinuxPackageMapping.scala#L74 is wrong, because File.exists returns false for broken symlinks.

Using "ln -f -s" should fix this.

Thanks for the issue and diagnosis! I'm more than happy to take a patch if you get time before I have a chance to fix this :).

This seems already be fixed: https://github.com/sbt/sbt-native-packager/blob/master/src/main/scala/com/typesafe/sbt/packager/linux/LinuxPackageMapping.scala#L76

I tested it and I can make multiple debian:packageBin calls, without failing.

Great! I'll mark as resolved, should be in the next release.
