How to read line by line and get all subcontent using jenkins

Question

I am writing a jenkins job to get all subcontent in a file.

the structure of this file looks like this:

 xxx.xxx.xxx.xxx.xxx.xxx,
 aa.aaa.aaa.aaa.aaa..aaa
 bb.bb.bbb.bb.bbbb.bbb:={orga=orga1, team=team1},
 ee.ee.bbb.ee.bbbb.eee:={orga=orga2, team=team3}

my goal is to get all subcontent which contains orga and team

I have tried

 def lines = new File(it.path).readLines()
                        def result = lines.findAll {it.contains(':={orga')}
                        println result.toString()

but I got Jenkins error through building.

any solutions?
