💡 Hint

Common Mistakes

Using a name not configured in Jenkins global libraries.

Forgetting quotes around the library name.

The library step loads the global shared library by its configured name, here 'my-shared-lib'.

💡 Hint

Common Mistakes

Using a function name not defined in the library.

Missing parentheses when calling the function.

The function buildApp() is called from the shared library after loading it.

Fix the error in the global library configuration snippet to specify the SCM repository URL.

Jenkins

libraries {
  myLib {
    scm {
      git {
        url = '[1]'
      }
    }
  }

💡 Hint

Common Mistakes

Using SSH URL without proper Jenkins credentials.

Omitting the .git suffix.

The SCM URL must be a valid Git HTTPS URL ending with .git for Jenkins to clone the repository correctly.

Fill both blanks to configure the global shared library with default version and allow override.

Jenkins

libraries {
  myLib {
    defaultVersion = '[1]'
    allowVersionOverride = [2]
  }
}

Drag options to blanks, or click blank then click option'

Cfalse

Dmaster

💡 Hint

Common Mistakes

Using 'master' when the repo uses 'main'.

Setting allowVersionOverride to false when override is needed.

The defaultVersion is usually set to the main branch name, and allowVersionOverride set to true allows pipelines to specify other versions.

5fill in blank

hard

Fill all three blanks to define a global shared library with name, SCM URL, and default version.

Jenkins

libraries {
  [1] {
    scm {
      git {
        url = '[2]'
      }
    }
    defaultVersion = '[3]'
  }
}

Drag options to blanks, or click blank then click option'

Cdevelop

Dmain

💡 Hint

Common Mistakes

Mixing branch names for defaultVersion.

Using incorrect URL format.

Mismatching library name and repo.

The library name is 'utilsLib', the SCM URL points to the GitHub repo, and the default version is set to 'main' branch.
