API Plugin with Curios API Support Build Error

I want to make my own API Plugin for 1.16.5 and higher and I got it Curios API work with 1.16.5.
But if I want to use the Curios API through Workspace API Settings I got this Build Error:
 

Executing Gradle task: build

Here is the curios api yaml code to add APIs through Plugins:

forge-1.16.5:
    gradle:
      repositories {
        maven {
            url = "https://maven.theillusivec4.top/"
        }
      }
      dependencies {
        runtimeOnly fg.deobf("top.theillusivec4.curios:curios-forge:1.16.5-4.0.5.0")
        compileOnly fg.deobf("top.theillusivec4.curios:curios-forge:1.16.5-4.0.5.0:api")
        }
    update_files:
    - ~
name: "Curios API"

I don't think there is an error but know someone why I have this Build Error in MCreator?
