Project.task with type instead of name fails to find class

Help/Discuss
1

I’m attempting to clean up an existing gradle plugin. This is how a task is currently created, and I’m trying to move the task into a separate class.

        project.task('createScmAdapter', group: RELEASE_GROUP,
                description: 'Finds the correct SCM plugin') doLast this.&createScmAdapter```

If I attempt to use the gradle syntax that is detailed here like so:

        project.task('createScmAdapter', type: CreateScmAdapter.class) {
            group = RELEASE_GROUP
            description = 'Finds the correct SCM plugin'
        }

I get this error:


* Where:
Build file '/Users/tyler.thrailkill/Documents/code/test-project/build.gradle.kts' line: 1

* What went wrong:
An exception occurred applying plugin request [id: 'net.researchgate.release', version: '2.7.1-SNAPSHOT', artifact: 'net.researchgate:gradle-release:2.7.1-SNAPSHOT']
> Failed to apply plugin [id 'net.researchgate.release']
   > No such property: CreateScmAdapter for class: net.researchgate.release.ReleasePlugin

I don’t understand why it is failing to find the class, they are located in the same package.

Maybe I’m compiling something wrong? Here is the build.gradle for the plugin
