Hi Alexander,

Thank you for your response and the suggested fix.
I did not run into issues when installing the plugin using "pip install".
But in any case, I modified the import to what you suggested.

However, the problem I mentioned in my previous message still exists.
After the "pip install" I run "pip list" and confirm that the plugin is 
listed there.
But when trying to import a tosca package into the catalog murano doesn't 
seem to know about the new package format (here as mentioned in my 
previous post).

The tosca package I am importing is attached just in case.


I hope I did not misunderstand your response.

Regards,

Hi Vahid,

Sorry for the delayed response.

I've run your plugin and I am facing an error during the loading of your 
plugin: the loader complains that it is unable to find the module named 
"heat_translator". 
As far as I can see, your plugin attempts the following import statement:
"from heat_translator import translator_shell" and this is the exact 
statement which fails. 
Most probably this happens because the heat_translator project does not 
expose its heat_translator.py file (the one defined in the root of the 
module) to the outer world, thus when you install it with pip this module 
cannot be found.
So, if you replace this import statement with something like 
"from translator import shell as translator_shell" this should work, since 
the "translator" module is properly exported by the heat-translator 
package.

Hope this helps

Hello,

I have been scratching my head at this issue for a couple of days without 
any success.

Here's the issue:
I try to install my plugin (can be found hereas WIP) using this command:

        pip install -e contrib/plugins/murano_heat-translator_plugin/

The installer runs and reports that "Successfully installed 
io.murano.plugins.oasis.tosca".
However, when I try to import a package to the catalog I see (while 
debugging) that the plugin format I just installed is not among the 
plugin_loader formats that murano discovers (here).

I run the same scenario for the Cloudify plugin and everything goes fine.

So it appears there is something wrong with my package (I was able to 
install it before). But I don't know where to look for the root cause of 
this issue.
Any pointers would be highly appreciated.

Thanks.
