💡 Hint

Common Mistakes

Using square brackets or curly braces instead of parentheses.

Forgetting to add parentheses after the function name.

The readFile function requires parentheses to pass the filename as an argument.

💡 Hint

Common Mistakes

Using parentheses instead of square brackets for named arguments.

Using curly braces which are for closures, not maps.

The writeFile function uses a map argument, so square brackets [] are used to pass named parameters.

💡 Hint

Common Mistakes

Using parentheses instead of square brackets.

Passing the path as a plain string without a key.

The archiveArtifacts function expects a map argument, so square brackets [] are needed.

4fill in blank

hard

Fill both blanks to create a map of file sizes for files larger than 1000 bytes.

Jenkins

def sizes = [file.name: [1] for file in files if file.length() [2] 1000]

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

Afile.length()

B>

C<

Dfile.name

💡 Hint

Common Mistakes

Using file name instead of file length for the map value.

Using less than operator instead of greater than.

The map should store the file size using file.length() and filter files larger than 1000 bytes using >.

5fill in blank

hard

Fill all three blanks to filter environment variables starting with 'BUILD_' and map their names to values.

Jenkins

def buildVars = [[1]: env.[2] for [3] in env.getEnvironment().keySet() if [3].startsWith('BUILD_')]

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

Avar

CvarName

💡 Hint

Common Mistakes

Using different variable names for key and value.

Using 'var' instead of 'varName' which is more descriptive.

Use varName as the loop variable and key for the map, and access the environment variable value with env.varName.
