Gemspec error due to 'spec.version = Additionals::VERSION'

[picman]

If I run a Ruby file in another Redmine plugin, I get the following error in Additionals;

ruby plugins/redmine_xapian/extra/xapian_indexer.rb

[!] There was an error parsing `Gemfile`: 
[!] There was an error parsing `Gemfile`:

A workaround is to modify lib/additionals/version.rb as follows:

# frozen_string_literal: true

module Additionals
-- VERSION = '3.0.3-master' unless defined? VERSION
++ VERSION = '3.0.3-master'
end

Me too having this problem. Many thanks for your workaround! Probably additionals plugin could be made more stable...

Hi @picman,

do you get this error with latest additionals, yet? I never had this problems you described with other plugins.

[picman]

With the master branch:

$ ruby plugins/redmine_xapian/extra/xapian_indexer.rb

[!] There was an error parsing `Gemfile`: 
[!] There was an error parsing `Gemfile`: 
[!] There was an error while loading `additionals.gemspec`: uninitialized constant Additionals::PluginVersion::VERSION. Bundler cannot continue.

The reason is unclear for me, but, can't you simple remove the check unless defined? VERSION. Why is it there?

[alexandermeindl]

Because this plugin can be installed as Gem. I did not find a solution for this without initializing VERSION constant twice. That is the reason. If I find a solution for that, I can remove this check.
