assembleTask is null in android gradle plugin 2.2-alpha2 for spoon plugin

Question

In the zipalign task creation method from gradle plugin

        InstantRunBuildContext instantRunBuildContext = this.getScope().getVariantScope().getInstantRunBuildContext();
        this.zipAlignTask = this.taskManager.createZipAlignTask(taskName, instantRunBuildContext, inputFile, outputFile);
        this.assembleTask.dependsOn(new Object[]{this.zipAlignTask});
        return this.zipAlignTask;

Now, assembleTask is null and in turn will throw

Caused by: org.gradle.api.InvalidUserDataException: A dependency must not be empty

I have checked earlier version, assembleTask has the actual assemble task
