I have a project with a few different native components to build, and the build script was getting large enough that I wanted to break out the component config into their own build script files, using `apply from:` to aggregate them into `build.gradle`.

I have a few model-space tasks defined with each component, and in the main `build.gradle` file, I’d like to create a `dependsOn` relationship between one of the tasks in one component’s build script and a task in another component’s build script.

But, I can’t find a way, from within `build.gradle` to refer to either of these tasks without getting an error like this:

```gradle
* What went wrong:
A problem occurred configuring root project 'project-x'.
> Exception thrown while executing model rule: tasks { ... } @ build.gradle line 26, column 5
   > Could not find property 'someComponentTask' on task ':tasks'.

```

_Question_: Given the basic build script structure shown below, how can I change `build.gradle` so it correctly establishes a dependency between a model-space task defined in `buildSomeComponent.gradle` and a different model-space task defined in `buildSomeOtherComponent.gradle`?

**build.gradle:**

```gradle
apply from: 'buildSomeComponent.gradle'
apply from: 'buildSomeOtherComponent.gradle'

model {
    tasks {
        someComponentTask.dependsOn someOtherComponentTask
    }
}

```

**buildSomeComponent.gradle:**

```gradle
model {
    components {
        // component config here
    }
    tasks {
        someComponentTask(Exec) {
            // exec something
        }
    }
}

```

**buildSomeOtherComponent.gradle:**

```gradle
model {
    components {
        // component config here
    }
    tasks {
        someOtherComponentTask(Exec) {
            // exec something
        }
    }
}

```

Never mind! Found that the task I was trying to set `.dependsOn` for had not been given a task type. As if, for example, the `someOtherComponentTask` definition above had been declared like so:

```gradle
    tasks {
        someOtherComponentTask {
        }
    }

```
