Debugging module installation on Drupal 7 with NetBeans

After following Configuring NetBeans, a very informative post on Drupal, I could still not debug my module on NetBeans 8.1. My main problem was that the breakpoints set on any of my module's files appeared as broken. In order to fix this, I needed to let NetBeans know which server request calls the module's code.

The Server request

Using Chrome's "Inspect" feature on the /admin/modules page after enabling my module and submitting the form, I found out that the module installation was being initiated by a POST request to "http://.../admin/modules/list/confirm".

I had created an apache virtual site to host it. On NetBeans, I included the whole Drupal 7 web tree as the project source (var/www/drupal7), and modified the project's Run Configuration accordingly (right click on the project's name > Properties):

Project Properties - Run Configuration

On the Advanced... settings window, I added the following Path Mapping:

• Server Path: http://mylocalserver.local/admin/modules/list/confirm
• Project Path: click on the ... and browse to the directory where your module is installed: /var/www/drupal7/sites/all/modules/my_module

Project Properties - Run Configuration - Advanced...

After this, the break points set on the files under .../my_module appeared and worked just fine.
