Run Configuration Management
This document describes main classes to work with run configurations and common use case.
- Configuration Type
- Configuration Factory
- Run Configuration
- Settings Editor
- Refactoring Support
- Creating Configurations from Context
- Running from the Gutter
The starting point for implementing any run configuration type is the
ConfigurationType interface. The list of available configuration types is shown when a user opens the ‘Edit run configurations’ dialog and executes ‘Add’ action:
Every type there is represented as an instance of
ConfigurationType and registered like below:
<configurationType implementation="org.jetbrains.plugins.gradle.service.execution.GradleExternalTaskConfigurationType" />
The easiest way to implement this interface is to use the
ConfigurationTypeBase base class. In order to use it, you need to inherit from it and to provide the configuration type parameters (ID, name, description and icon) as constructor parameters. In addition to that, you need to call the
addFactory() method to add a configuration factory.
The key API of
ConfigurationFactory, and the only method that you’re required to implement, is the
createTemplateConfiguration method. This method is called once per project to create the template run configuration.
All real run configurations (loaded from the workspace or created by the user) are called by cloning the template through the
The run configuration itself is represented by the
RunConfiguration interface. A ‘run configuration’ here is some named profile which can be executed, e.g. application started via
main() class, test, remote debug to particular machine/port etc.
Here is an example of a Java run configurations defined for a particular project:
When implementing a run configuration, you may want to use one of the common base classes:
RunConfigurationBaseis a general-purpose superclass that contains the most basic implementation of a run configuration.
LocatableConfigurationBaseis a common base class that should be used for configurations that can be created from context by a
RunConfigurationProducer. It supports automatically generating a name for a configuration from its settings and keeping track of whether the name was changed by the user.
ModuleBasedConfigurationis a base class for a configuration that is associated with a specific module (for example, Java run configurations use the selected module to determine the run classpath).
That common run configuration settings might be modified via:
getComponent()method is called by the IDE and shows run configuration specific UI.
resetFrom()is called to discard all non-confirmed user changes made via that UI.
applyTo()is called to confirm the changes, i.e. copy current UI state into the target settings object.
That run configuration settings are persistent, i.e. they are stored at file system and loaded back on the IDE startup. That is performed via
readExternal() methods of
RunConfiguration class correspondingly.
The actual configurations stored by the IntelliJ Platform are represented by instances of the
RunnerAndConfigurationSettings class, which combines a run configuration with runner-specific settings, as well as keeping track of certain run configuration flags such as “temporary” or “singleton”.
Dealing with instances of this class becomes necessary when you need to create run configurations from code. This is accomplished with the following two steps:
RunManager.createConfiguration()creates an instance of
RunManager.addConfiguration()makes it persistent by adding it to either the list of shared configurations stored in a project, or to the list of local configurations stored in the workspace file.
Most run configurations contain references to classes, files or directories in their settings, and these settings usually need to be updated when the corresponding element is renamed or moved.
In order to support that, your run configuration needs to implement the
In your implementation of
getRefactoringElementListener(), you need to check whether the element being refactored is the one that your run configuration refers to, and if it is, you return a
RefactoringElementListener that updates your configuration according to the new name and location of the element.
Many plugins support automatic creation of run configurations from context, so that the user can click, for example, on an application or test class and automatically run it using the correct run configuration type. In order to support that, you need to provide an implementation of the
interface and to register it as
<runConfigurationProducer> in your
plugin.xml. (Note that this API has been redesigned in IntelliJ IDEA 13; the old
RuntimeConfigurationProducer is a much more confusing version of the same API).
The two main methods that you need to implement are:
setupConfigurationFromContext()receives a blank configuration of your type and a
ConfigurationContextcontaining information about a source code location (accessible by calling
getPsiLocation()). Your implementation needs to check whether the location is applicable for your configuration type (for example, if it’s in a file of the language you’re supporting). If not, you need to return false, and if it is, you need to put the correct context-specific settings into the run configuration and return true.
isConfigurationFromContext()checks if the specified configuration of your type was created from the specified context. Implementing this method allows you to reuse an existing run configuration which is applicable to the current context instead of creating a new one and possibly ignoring the customisations the user has performed in the existing one.
Note that, in order to support automatic naming of configurations created from context, your configuration should use
LocatableConfigurationBase as the base class.
