Setup

This Addon requires the following installation steps.

Add configuration to pom.xml

To use this addon, you must add it as a dependency in the pom.xml of your forge-addon classified artifact:

<dependency>
   <groupId>org.jboss.forge.addon</groupId>
   <artifactId>configuration</artifactId>
   <classifier>forge-addon</classifier>
   <version>${version}</version>
</dependency>

Features

User-scoped Configuration

The Configuration object associated to a user is the default option when injected or retrieved from the AddonRegistry. It stores properties in a XML format in <USER_HOME>/.forge/config.xml.

@Inject private Configuration configuration;
configuration.setString("foo","value");
String foo = configuration.getString("foo");
// foo == "value"
Tip

If your addon uses a container that does not support "@Inject" annotations, services such as the Configuration may also be accessed via the AddonRegistry:

Imported<Configuration> imported = addonRegistry.getServices(Configuration.class);
Configuration configuration = imported.get();
Project-scoped Configuration

Project-scoped configuration is provided by accessing the ConfigurationFacet installed by default in any project. It stores the properties in an XML format in a file named .forge_settings inside the project. It is important to note, however, that this file is only created if a configuration property is explicitly set for the first time.

Project project = ...
ConfigurationFacet facet = project.getFacet(ConfigurationFacet.class);
Configuration config = facet.getConfiguration();
Tip
 Project-scoped configuration properties no longer falls back to the user-scoped configuration properties as in Forge 1.x.
Configuration Factory

If a specific file is meant to be used as a configuration file, you can use the ConfigurationFactory to handle it as a Configuration object

@Inject
private ConfigurationFactory configurationFactory;

FileResource<?> resource= ...// Fetch the FileResource representation of a file
Configuration config = configurationFactory.getConfiguration(resource)
