How can downgrade to taskwarrior 2.6.2 ?

[hwypengsir]

I want to downgrade to taskwarrior 2.6.2 because of the complicated sync in taskwarrior 3,if there are some free task server can choose to use ,not to downgrade.

Install it by compiling:

tar xzf task-3.3.0.tar.gz              
cd task-3.3.0                        
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release .  
cmake --build build                              
sudo cmake --install build                       
cd .. ; rm -r task-3.3.0.tar.gz

How can remove it completely?

Do you want to downgrade your task data, or remove Taskwarrior 3.3.0?

CMake doesn't have a --uninstall option, but

sudo xargs rm < build/install_manifest.txt

should remove the files it created (maybe with rm -i so you can check it's not doing anything unexpected -- I'm not 100% sure e.g., /usr/bin isn't in there)

To downgrade the data, use task export to export your tasks from Taskwarrior 3, then install Taskwarrior 2, then task import.
