v0.8 - unsupported Gradle DSL method found: 'dependsOn()'

[pbellchambers]

I'm using Java 8, and Gradle 2.1, and my build script has a dependsOn() on the cucumber task:

cucumber.dependsOn startLocal

With v0.8 of the cucumber plugin my build always fails with the following error, if I go back to the previous version (0.7.2) the build works fine:

FAILURE: Build failed with an exception.

* Where:
Build file 'build.gradle' line: 220

* What went wrong:
A problem occurred evaluating project ':mainapp'.
> Could not find method dependsOn() for arguments [task ':mainapp:startLocal'] on com.excella.gradle
.cucumber.CucumberConvention_Decorated@4462efe1.

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
org.gradle.api.GradleScriptException: A problem occurred evaluating project ':mainapp'.

I see. I didn't realize that DSLs are the tasks themselves, really. I'll fix it as soon as I can.

Now that I looked at it closer, it seems I broke a feature that is not quite obvious.

The cucumber {} DSL is supposed to configure the plugin more than just the default instance of CucumberTask named cucumber.

I followed what the Gradle team advises and replaced (some of) the never-officially-published convention mechanism by the extension one. However, the convention mechanism auto-magically mixes the convention object (the DSLobject) with the task of the same name as far as I can tell.

To properly implement a dependsOn plugin-level config, I would have to add it to the extension/convention bean.

If you want to upgrade to v0.8, I would advice to explicitly deal with the task by writing the following for now;

project.tasks.cucumber.dependsOn startLocal

Not sure what the best approach is, really.
