In a bamboo plugin. How do I get the values for substituted variables?

[Geoff Bullen]

I am writing a custom task.  My starting point was https://developer.atlassian.com/bamboodev/bamboo-tasks-api/writing-a-task-with-a-user-interface

If I use a variable in the UI text field, I can't figure out how to get at it's value in my code.  For example if I enter ${bamboo.myVariable}, how do I get at it's value?

taskContect.getConfigurationMap() has ${bamboo.myVariable} 

[Preston Gilchrist]

taskContext.getConfigurationMap().get("my.configuration.variable.from.ftl"));

Make sure that your configuration class is complete and has the following method implemented:

@NotNull
@Override
public Map<String, String> generateTaskConfigMap(@NotNull ActionParametersMap params, @Nullable TaskDefinition previousTaskDefinition)
{
final Map<String, String> config = super.generateTaskConfigMap(params, previousTaskDefinition);
taskConfiguratorHelper.populateTaskConfigMapWithActionParameters(config, params, FIELDS);
return config;
}
