Resolving the com.tang.intellij.lua.project.LuaSourceRootManager Exception in IntelliJ IDEA

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 class 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().

Understanding the Error Message

The error message is a result of a misconfiguration in the plugin's code. The LuaSourceRootManager class is intended to be a service, but it is currently defined as a component. This discrepancy causes the plugin to fail when attempting to access the service.

Resolving the Issue

To resolve this issue, you can follow one of two approaches:

Approach 1: Convert the Component to a Service

You can modify the LuaSourceRootManager class to extend the Service class instead of Component. This will allow the class to be used as a service.

class LuaSourceRootManager : Service {
    // Service implementation
}

Approach 2: Change the Call to project.getComponent()

Alternatively, you can modify the code that calls project.getComponent() to instead call project.getService().

val luaSourceRootManager = project.getService(LuaSourceRootManager::class.java)

Example Use Case

Here is an example of how you can use the LuaSourceRootManager service in your plugin code:

class LuaSourceRootManager : Service {
    override fun getComponentName(): String {
        return "LuaSourceRootManager"
    }

    fun getLuaSourceRoots(): List<SourceRoot> {
        // Return a list of Lua source roots
    }
}

class LuaPlugin : Plugin {
    override fun getServices(): List<Service> {
        return listOf(LuaSourceRootManager())
    }

    fun getLuaSourceRoots(): List<SourceRoot> {
        val luaSourceRootManager = project.getService(LuaSourceRootManager::class.java)
        return luaSourceRootManager.getLuaSourceRoots()
    }
}

Conclusion

Resolving the com.tang.intellij.lua.project.LuaSourceRootManager exception in IntelliJ IDEA requires modifying the plugin's code to either convert the component to a service or change the call to project.getComponent(). By following the steps outlined in this article, you can resolve this issue and continue working with the EmmyLua plugin in IntelliJ IDEA.
