Method Detail

canCreate

public String canCreate(PluginArtifact pluginArtifact)
                 throws PluginParseException

Description copied from class: AbstractPluginFactory

Determines if this deployer can handle this artifact by looking for the plugin descriptor

Specified by:

canCreate in interface PluginFactory

Overrides:

canCreate in class AbstractPluginFactory

Parameters:

pluginArtifact - The artifact to test

Returns:

The plugin key, null if it cannot load the plugin

Throws:

PluginParseException - If there are exceptions parsing the plugin configuration when the deployer should have been able to deploy the plugin

getDescriptorInputStream

protected InputStream getDescriptorInputStream(PluginArtifact pluginArtifact)

Specified by:

getDescriptorInputStream in class AbstractPluginFactory

isValidPluginsVersion

protected com.google.common.base.Predicate<Integer> isValidPluginsVersion()

Specified by:

isValidPluginsVersion in class AbstractPluginFactory

create

public Plugin create(PluginArtifact pluginArtifact,
            ModuleDescriptorFactory moduleDescriptorFactory)
              throws PluginParseException

Deploys the plugin artifact. The artifact will only undergo transformation if a plugin descriptor can be found and the "Atlassian-Plugin-Key" value is not already defined in the manifest.

Parameters:

pluginArtifact - the plugin artifact to deploy

moduleDescriptorFactory - The factory for plugin modules

Returns:

The instantiated and populated plugin

Throws:

PluginParseException - If the descriptor cannot be parsed

IllegalArgumentException - If the plugin descriptor isn't found, and the plugin key and bundle version aren't specified in the manifest
