如何在 Groovy 中将文件中的特定行存储在数组中？

Question

I am interested if there is a easy way to store a specific line from a file into an array in Groovy (i need it for GroovyAxis in Jenkins). The file would look like this:

var1="value1 value2 etc"

var2="a b etc"

var3="test1 test2 test3 etc"

I would need test1 test2 test3 etc from var3 to be stored in an array. Right now i use this:

def words = []
new File( '/home/workstation/jenkins/params' ).eachLine { line ->
    words << line
}

But it stores each line i have into an array, so i have to heavily workaround the config file to get the job done.

Thank you very much

Answer 1

You are very close!

def words = [:]
new File( '/home/workstation/jenkins/params' ).eachLine { line ->
    (var, value) = line.split('=')
    words << [(var): value.split(' ')]
}

The result is a map of arrays. The key is the variable name and the value is an array.

update

Oh, it's a property file...

Properties properties = new Properties() 
File propertiesFile = new.    File('/home/workstation/jenkins/params') 
propertiesFile.withInputStream { properties.load(it) } 
def result = properties.var3.split(' ').collect { item.minus('"') }
return result

ConfigSlurper can be useful to load properties/configurations :

def config = new ConfigSlurper(new File("my.conf").toURL())
assert config.var2 == "a b etc"

Answer 3

//cat /tmp/words.txt
//It's must be file Format
//SOME_DETAILS:1234-A0;1456-B1;2456-B0;3436-D0;4467-C0

stage("test"){

    def testArray=[]
    new File('/tmp/words.txt').splitEachLine("[:;]"){line->
        if(line[0]=='SOME_DETAILS')testArray=line[1..-1]
    }
    println testArray
}
