Groovy Postbuild in Jenkins, parsing the log for strings and counting them

Question

I am new to Groovy and am trying to set up a postbuild in Jenkins that allows me to count strings and determine if the build succeeded by how many the count returns at the end.

Here is my example code :

class Main {

  def manager = binding.getVariable("manager")
  def log = manager.build.logFile.text
  def list = log
  def JobCount = list.count {it.startsWith("====") && it.contains("COMPLETE")}
  if (JobCount == 7) {
      manager.listener.logger.println("All Jobs Completed Successfully")
  } else {
      manager.addWarningBadge("Not All Jobs Have Completed Successfully")
      manager.buildUnstable()  
  }
}

I am looking for a specific string that gets printed to the console when the test has completed successfully. The string is "====JOB COMPLETE====" and I should have 7 instances of this string if all 7 tests passed correctly.

Currently when I run this code I get the following error :

Script1.groovy: 6: unexpected token: if @ line 6, column 5.
   if (JobCount == 7)
   ^

Any help would be greatly appreciated

manager.build.logFile.text returns the whole file text as String.

What you need is readLines():

def list = manager.build.logFile.readLines()
def JobCount = list.count {it.startsWith("====") && it.contains("COMPLETE")}

and of course as mentioned below, the Jenkins Groovy Postbuild plugin runs Groovy scripts, so you will have get rid of the enclosing class declaration (Main)

You have statements directly inside your class, without being in a method, which is not allowed in Java/Groovy. Since this is Groovy, you can run this as a script without the class at all, or put the offending code (the if statement) inside a method and call the method.

I moved everything out of the class as you had mentioned. I was not aware that was unnecessary, thanks for that. Now when I run this without the main class, I get an error, that says no signature of method : java.lang.string.count() is applicable for argument types: (Script1$_run_closure1) values: [Script1$_run_closure1@77a3b365] – andrewkro Aug 19 '15 at 19:02
After that it says Possible solutions: count(java.lang.CharSequence), count(java.lang.String), toSet(), toSet(), toURL(), toURL() – andrewkro Aug 19 '15 at 19:02

Perhaps you're missing a closing }

def JobCount = list.count {it.startsWith("====") && it.contains("COMPLETE")}

Ah, good catch. I added this } back in where it should be and now get the error: Script1.groovy: 6: unexpected token: if @ line 6, column 5. if (JobCount == 7) { ^ – andrewkro Aug 18 '15 at 20:55
arrow is under the if in the first if statement – andrewkro Aug 18 '15 at 20:55
I removed that last bracket when I fixed the one you commented before. – andrewkro Aug 18 '15 at 21:00
