If you have the jar file of the project then you can do it easily, else you need to put the main code of the library into the src folder and then use.
where can i get that file i read in the link i need jar file but i don't know how to get it please say where it is
in this lib
If it doesn't has, and if you need to use it, you have to create it, it's easy.
Step : 1
Download JAR or AAR or both file into your computer or laptop.
Step : 2 (In case of AAR)
Change the file extension from .aar to .zip and open zip file and extract .jar file.
Step : 3
Past your .jar and .aar file into lib folder.
path is : appinventor-sources/appinventor/lib
Step : 4
Add path of external libraries into build.xml file.
Path is : appinventor-sources/appinventor/components/build.xml
Reference : see this
Step : 5
Add @UsesLibraries annotation into your code.
Example : @UsesLibraries(libraries = "example1.jar," + "example2.jar")
Reference: see this

Where is the file in this git repository
you can search into maven or you can contact developer
Doing a quick search for the library gives me the following results. I'm not sure which version you need, but you can find out by reading the documentation.

No. You cannot find jar for every repo.
