             Summary: Local development of plugins with variables need 
variables in fetch.json
                 Key: CB-12594
                 URL: https://issues.apache.org/jira/browse/CB-12594
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android, CLI, iOS, Plugins
            Reporter: Philipp Kursawe


Consider a plugin that defined a preference in its plugin.xml

When you use the CLI feature to save plugins into config.xml and also add the 
variables for this plugin, the CLI complains when adding the plugin during 
platform restore (missing variables):

{code:title=plugin.xml}
<?xml version="1.0" encoding="UTF-8"?>
<plugin
    xmlns="http://apache.org/cordova/ns/plugins/1.0";
    xmlns:android="http://schemas.android.com/apk/res/android";
    id="cordova-plugin" version="1.0">

    <preference name="COMPANY_NAME" />

{code}

{code:title=config.xml}
<plugin name="cordova-plugin" spec="cordova-plugin-insert-io">
        <variable name="COMPANY_NAME" value="acme" />
{code}

When removing a platform and re-adding it this is the result:

{code}
Installing "cordova-plugin" for android

{code}

It seems, the CLI checks the fetch.json file, and if that does not contain the 
variables, it fails with this error. Manually adding the variables to the 
fetch.json file, or re-installing the plugin helps (reinstalling rewrites the 
fetch.json file).

That means, if we add a variable to our plugin during plugin development, we 
would have to remove the plugin (unlink) it first, and then re-add it, 
specifying all the variables at the CLI.

How it should actually work is that config.xml has precedence over whatever it 
says in fetch.json. Or get rid of fetch.json alltogether. I think its only 
there for historical reasons?
