Cannot define multiple 'included' blocks for a Concern (ActiveSupport::Concern::MultipleIncludedBlocks)

[hi-ko]

On Ubuntu 18 with with Redmine 4.0.4.stable.18593 I'm not able to start redmine with the plugin v.3.0 installed. Any idea?

Finally I got it running: the module doesn't work with symlinks. This is the only plugin we use having an issue with symlinks. I tried relative, absolute but only when saving the plugin in the real path inside redmine home the system starts. Maybe this could be fixed? Thanks for reading.

@hi-ko thanks for the feedback, this could definitely be fixes

could you give me an exemple of another Redmine plugin you are using which works fine with symlinks? I'd want to take a look at their code to see how they handle this

[hi-ko]

@felipebatista thanks for taking care. We use e.g.

• additionals
• redmine_github_hook
• redmine_ldap_sync
• serveral plugins from redmineup (requires registering to get the code)

Unfortuntaley I don't speak ruby - so I'm not really a valuabe assistant. The error is similar if redmine runtime user has no write access to the module dir although read access should be sufficient.

hello @hi-ko, please try the new unreleased versions 2.1-alpha1 or 3.1-alpha1

• 2.x versions of this plugin are compatible with Redmine 3.x
• 3.x versions of this plugin are compatible with Redmine 4.x

thank you!

[hi-ko]

great - works as expected:

• plugin could be owned by root allowing only read access
• plugin could be linked from dir outside redmine

thanks!
