Bug Report

Problem

cordova plugin add with searchpath doesn't work. CLI will prompt error code 404 not found.

Command or Code

Suppose I have a locally built cordova plugin [email protected] in folder C:\SAP\KapselSDK4.2.7snapshot\plugins.

Run the command cordova plugin add kapsel-plugin-corelibs --searchpath C:\SAP\KapselSDK4.2.7snapshot\plugins --verbose
then following error occurs:

No scripts found for hook "before_plugin_add".
No version specified for kapsel-plugin-corelibs, retrieving version from config.xml
No version for kapsel-plugin-corelibs saved in config.xml or package.json
Not checking npm info for kapsel-plugin-corelibs because searchpath or noregistry flag was given
Calling plugman.fetch on plugin "kapsel-plugin-corelibs"
fetch: Installing kapsel-plugin-corelibs to C:\Users\i062893\cordova-workspace\app
Running command: npm install kapsel-plugin-corelibs --production --save
Command finished with error code 1: npm install,kapsel-plugin-corelibs,--production,--save
Failed to fetch plugin kapsel-plugin-corelibs via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.

Please note that the workaround is to append version in the plugin name: so if I run command cordova plugin add [email protected] --searchpath C:\SAP\KapselSDK4.2.7snapshot\plugins --verbose
The plugin can be added successfully:

No scripts found for hook "before_plugin_add".
