How to get sub content after running readFile in Jenkins - jenkins

Question

I have a question about how to get sub content after running readFile in Jenkins.
I print the content after readFile method of groovy in Jenkins
the content looks like this
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: asdfasdf
Team: {org=org1, team=team1}
ABCD: {org=org2, team=team2}
ABCDE: {org=org3, team=team3}
Bundle-Vendor: xxxxx
I just want to get this line in the content
Team: {org=org1, team=team1}
ABCD: {org=org2, team=team2}
ABCDE: {org=org3, team=team3}
but how??
any Solutions?

Answer 1

The content of your file looks like it is a properties file, so you can use the readProperties keyword which is part of the Pipeline Utility Steps to read the file into a map, allowing you easy access to all the values:
readProperties: Read properties from files in the workspace or text.
Reads a file in the current working directory or a String as a plain text Java Properties file. The returned object is a normal Map with String keys. The map can also be pre loaded with default values before reading/parsing the data.
You now have easy access to the keys and values.
In your case it can look like:
def props = readProperties file: 'YOUR_FILE_PATH'
// You can now access all values from the props map
def content = "Team: ${props.Team}"
If you just want the line based on parsing the file content you can read the file, split the content by new lines and use something like the following:
def lines = readFile('YOUR_FILE_PATH').split("\n").trim()
// Get a constant line
def content = lines[4]
// Get a line by prefix
def content = lines.find{ it.startsWith('Team')}
