Groovy: temporary file with autodelete

File.createTempFile("temp",".tmp").with {
   //deleteOnExit()  // Including this line will cause the temp file to be deleted automatically

   write "Hello world"    // write to the temp file
   println absolutePath   // This is the path to the file
}

File tf = File.createTempFile("temp",".tmp")
tf.write("Hello world")   // write to the file
println(tf.absolutePath)  // path to the file
tf.delete()               // delete the file

Thank you very much, your answer resolved my issue:

def map1 = [:]
map1.put('jfr_1', "Hello World!")
def i = 1
def x = map1."jfr_$i"
println "x = " + "${x}" ----> x = Hello World!


 def jfr_1 = "Hello World!"
def i = 1
    def x = "jfr_$i"
    println "${x}"

Above code prints: jfr_1 instead of Hello World! What I'm doing wrong?

Nothing. That's the expected behaviour.

Thank you for the reply, how can I print "Hello World!" instead Using PERL print ($$x) will print "Hello World!".

Even in Perl you should not do that and you should "use strict" to make sure you don't do it by mistake. In Perl you'd use a hash in Groovy a map for that kind of data structure.
