Gradlew tasks not showing all tasks

gradlew tasks --all gives the same results. I do not understand why the same codebase would yield different tasks between my local machine and the Ubuntu instance.

For example for the group “Android tasks”, my local machine shows:-
androidDependencies - Displays the Android dependencies of the project.
signingReport - Displays the signing info for the base and test modules
sourceSets - Prints out all the source sets defined in this project.

while for the same group, the ubunut instance shows : -
sourceSets - Prints out all the source sets defined in this project.`
