# Which Packages to Configure?

I don't know what packages to configure

## Problem <a href="#problem" id="problem"></a>

The SeaLights build scan needs the prefix of the packages to focus the scan only on your code and not include third-party code.\
Sometimes you don't know what the package prefix is.

## Solution <a href="#solution" id="solution"></a>

The Sealights build scanner can show you a list of prefixes in the Java artifacts from your application. You do so by using the following command:

{% code overflow="wrap" lineNumbers="true" %}

```sh
java -jar sl-build-scanner.jar -modules <path/to/jars/for/analysis>
```

{% endcode %}

If you do not provide a path to the command it will analyze the files from the current working directory.

In the screenshot below, you'll see an illustration of the result from the `modules` command. for this specific artifact analyzed the relevant packages are highlighted.\
The packages included parameter (`-pi` or `-packagesincluded`) used for the `scan` command of this artifact will be: `"*com.kuhniverse.*"`

### Additional parameters <a href="#additional-parameters" id="additional-parameters"></a>

Additional options are available for this command:

{% code overflow="wrap" lineNumbers="true" %}

```sh
java -jar sl-build-scanner.jar -modules <path/to/jars/for/analysis> [-r] [-modulePathLength <arg>]
```

{% endcode %}

| `r`                | Recursive search all folders under the workspace path                                                                                                                                                   |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `modulePathLength` | <p>Print modules with the length provided as a parameter (default value is 2).<br>For example, two significant names will appear as <em>io.sealights.*</em> and single will appear as <em>io.*</em></p> |
