💡 Hint

Common Mistakes

💡 Hint

Common Mistakes

Using a wrong function name that does not exist in the library.

Trying to call the function without the library object.

You call the function by its exact name defined in the shared library, here buildApp.

Common Mistakes

Using wrong branch names like 'master' if the repo uses 'main'.

Mixing up library name and branch name.

The library name is 'my-shared-library' and the default branch is usually 'main'.

Using 'branch' instead of 'tag' for version.

Not using modernSCM for retriever.

The library name is 'custom-shared-lib', retriever is 'modernSCM(scm)', and version is specified by 'tag'.
