Is there a way to list task dependencies in Gradle?

Prior to Gradle 3.3, you could use the --all flag to get a more detailed listing of the available tasks and the task dependencies:

gradle tasks --all

The dependency reporting was removed from this task as of Gradle 3.3 for performance reasons. This change and its rationale was documented in the Gradle 3.3 release notes.

list the tasks and what tasks they depend on (sort of like maven's depenceny:tree but for tasks)

for this you can use --dry-run (or -m) option which lists tasks which are executed in order for particular command, but does not execute the command, e.g.

gradle assemble --dry-run
