I am learning some kotlin concepts. I don't really understand yet.

I added SafeArgs classpath and plugin to the appropriate build.gradle file.

Here's the classpath:

classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.3.1"

And Here's the plugin

id 'androidx.navigation.safeargs.kotlin'

Even After this I still get an missing or conflicting dependencies error

Cannot access class 'com.example.testingtaskmanager.ui.updatefragment.UpdateFragmentArgs'. Check your module classpath for missing or conflicting dependencies

I now understand that the SafeArgs needs to be in a consistent version with some other dependiency, but I am not really similar with this.

Here's a picture of the error for clarify sake;

So please I am going to link all my build.gradle file both app and project level, so you can take a look at it, if it's not too much to ask.. Thanks in Advance.

build.gradle app level;

I'd really apppreciate any help, Thanks so much in advance. If you need any information I am more than happ to provide.

Thanks again.

CodePudding user response：

Have you tried using the same version for the plugin as you use for navigation right now you have 2.3.1 for safeargs and 2.3.5 for base navigation dependency.

classpath "androidx.navigation:navigation-safe-args-gradle-plugin:2.3.1"

// Navigation Component
implementation 'androidx.navigation:navigation-fragment-ktx:2.3.5'
implementation 'androidx.navigation:navigation-ui-ktx:2.3.5'

CodePudding user response：

You must have android.useAndroidX=true in your gradle.properties file

Dependency Changes for version 2.3.1

• navigation-ui now depends on DrawerLayout 1.1.1
• Safe Args now depends on KotlinPoet 1.6.0
• Safe Args now depends on AGP 4.0.1 (android gradle plugin)
