@kardapoltsev can you merge this into the 0.7.x and 0.8.x branch?

[kardapoltsev]

Well... :) Am I need to cherry-pick this commit into this branches? I don't know what we have currently in 0.7 and 0.8 branches. I'll know that it's my mistake but I know nothing about branches and releases in sbt-native-packager (:

[muuki88]

no problem @kardapoltsev :) Cherry-picking is the way to go. This is why we should start to merge only one-commit pull-requests as they are easier to integrated into different dev-branches.

These are the steps for integrating

git checkout master
git pull

if you haven't checked out the dev-branches do:

git checkout -b 0.7.x origin/0.7.x
git checkout -b 0.8.x origin/0.8.x

then

git checkout 0.7.x
git cherry-pick 3029508890b69b8122fac531a189a67d4687e971
git checkout 0.8.x
git cherry-pick 3029508890b69b8122fac531a189a67d4687e971
git push

If the cherry-pick doesn't work (for what ever reasons). We should reintegrate
the change in a separate pull requests as merging may introduce errors.

At the moment I'm just commenting if I integrated the commit. Maybe we should
add labels for that?

[kardapoltsev]

Merged into 0.7.x and 0.8.x.
Thanks @muuki88 for so detailed answer!
