# Scan behaviour matrix

The scanner works using a plugin architecture, so each scanner plugin have different capabilities and requirements. However, there are conditions that need to be met in order to any scanner plugin to work correctly. 

Considering the following condition:

<table><thead><tr><th width="181">Condition</th><th>Explanation</th></tr></thead><tbody><tr><td><strong>Language</strong></td><td>The language implemented by the plugin</td></tr><tr><td><strong>Build Tool</strong></td><td>The build tool used in the codebase</td></tr><tr><td><strong>Valid build required?</strong></td><td>Do we need the build to execute and complete successfully?</td></tr><tr><td><strong>Tool required?</strong></td><td>Do we need to execute the build tool installed?</td></tr><tr><td><strong>Invalid dependency?</strong></td><td>What happens if the project includes an invalid/unreachable dependency?</td></tr></tbody></table>

These are the level of support provided and the corresponding behaviour of the scanner

| Language                                                                            | Build Tool   | Valid build required? | Tool required?     | Invalid dependency? |
