Final answer:
In a Jenkins scripted pipeline, use conditional statements like 'if' with parameters or environment variables to control stage execution and skip certain stages based on conditions.
Step-by-step explanation:
To skip stages in a Jenkins scripted pipeline, you can use conditional statements to control the flow of execution based on certain conditions. For example, you can use the if statement to check a condition, and only execute a stage if the condition is true.
Alternatively, you can define a parameter at the start of the pipeline that determines which stages to run, and use this parameter within your if conditions. It's also possible to use environment variables to decide whether to skip stages.
Remember that Jenkins scripted pipelines are written in Groovy, so you have the full flexibility of the Groovy programming language to make complex decisions about which stages to execute.
