To install, copy the folder PapooCcm19Integration to custom/plugins/ .
If changes are made to the administration Javascript code, these must be compiled.
The development version of Shopware is required for this:
https://github.com/shopware/development
Install this (and if necessary create .psh.yaml along the lines of .psh.yaml.dist with the correct database and mailer settings).
Dependencies: apt install composer npm webpack node-webpack-merge node-copy-webpack-plugin
The plugin must be installed and activated in the installation.
Then:
./psh.phar administration:install-dependencies # only needed once (installs npm dependencies)
./psh.phar administration:build
After that the compiled JS can be found in PapooCcm19Integration/src/Resources/public and can be committed.
