Introduction

When working with the EmmyLua plugin in IntelliJ IDEA, you may encounter an error message indicating that the com.tang.intellij.lua.project.LuaSourceRootManager is requested as a service but is a component. This issue can be resolved by converting the component to a service or by changing the call to project.getComponent(). In this article, we will explore the possible causes of this error and provide step-by-step instructions on how to resolve it.

Understanding the Error Message

The error message com.tang.intellij.lua.project.LuaSourceRootManager requested as a service, but it is a component - convert it to a service or change call to project.getComponent() indicates that the LuaSourceRootManager class is being requested as a service, but it is actually a component. This is a common issue in IntelliJ IDEA plugins, where a class is being used as a service but is not registered as a service.

Possible Causes of the Error

There are several possible causes of this error, including:

  1. Incorrect registration of the component: The LuaSourceRootManager class may not be registered as a service in the plugin's plugin.xml file.
  2. Incorrect usage of the component: The plugin may be using the LuaSourceRootManager class as a service, but it is not registered as a service.
  3. Conflicting dependencies: There may be conflicting dependencies in the plugin's pom.xml file that are causing the issue.

Resolving the Error

To resolve the error, you can follow these steps:

Step 1: Check the plugin's plugin.xml file

Open the plugin's plugin.xml file and check if the LuaSourceRootManager class is registered as a service. If it is not, add the following code to the plugin.xml file:

<service id="com.tang.intellij.lua.project.LuaSourceRootManager" class="com.tang.intellij.lua.project.LuaSourceRootManager"/>

Step 2: Check the plugin's pom.xml file

Open the plugin's pom.xml file and check if there are any conflicting dependencies. If there are, remove them or update the dependencies to the latest version.

Step 3: Change the call to project.getComponent()

If the LuaSourceRootManager class is not registered as a service, you can change the call to project.getComponent() to use the project.getComponentManager().getComponent() method instead. This will allow you to retrieve the component without requesting it as a service.

Step 4: Rebuild and restart IntelliJ IDEA

After making the necessary changes, rebuild the plugin and restart IntelliJ IDEA. This should resolve the error and allow you to use the plugin without any issues.
