Can we just directly fetch the tasks with this approach no matter the project's gradle version is > or < 5? Since they look very similar.

// The original code is not implemented by me so I'm not aware of the history of it.

Sorry for long response, as far as I understand plugin's local gradle project model does not support some lazy tasks, so this commit was made as fix #1302 in which now plugin uses gradle built in model. I couldn't reproduce this bug though so I can try to unify these methods to be compatible with everything, but it surely will need more testing

List<GradleTask> tasks = new ArrayList<>();
TaskContainer taskContainer = project.getTasks();

if (taskContainer instanceof TaskContainerInternal) {
TaskContainerInternal taskContainerInternal = (TaskContainerInternal) taskContainer;
taskContainerInternal.discoverTasks();
taskContainerInternal.realize();
taskContainerInternal.forEach(task -> {
String buildFile = task.getProject().getBuildscript().getSourceFile().getAbsolutePath();
boolean debuggable = (task instanceof JavaExec) || (task instanceof Test);
GradleTask newTask = new DefaultGradleTask(task.getName(), task.getGroup(), task.getPath(),
task.getProject().getName(), buildFile, rootProject.getName(), task.getDescription(),
debuggable);

tasks.add(newTask);
cachedTasks.add(newTask);
});
}

return tasks;
}
