Find javac tasks in build.xml that does compile without line-number information

Majority of ANT build files for java proje use javac-task for compiling the java files. But if the javac task does not have debug=true or debug=yes, then compiled java-class files does not contain line numbers in stacktraces. Following groovy script will check all build files in given file and check all javac taks that does not have debug-flags setting off

def s1=System.currentTimeMillis()
def f = new  File('c:/all_build_files.txt')
def counter=0
def error=0
def noDebug=0
def noJavac=0
def debug=Boolean.getBoolean("debug")
f.eachLine{
   try{
       def file=it
       def project = new XmlSlurper().parse(new File(file))
       def tasks = project.target.javac
       if( tasks.size() > 0){
           noJavac++
           if(debug) println "javac tasks: ${tasks.size()}"
           def found=true
           def nfound=0  
           tasks.each{
               def flag=it.@debug
               if (!( flag =~ /yes/ || flag =~ /true/ )) {
                   nfound++
                   found=false  
               }
           }
           if(!found) {
               noDebug++
               println "${nfound} : ${file}"
           }
       }
       counter++
   }catch(Exception e){
       error++
       if(debug) println "${it} --> ${e}"
   }
}
def s2=System.currentTimeMillis()
def sd=s2-s1
println "Parsed files:${counter}, Errors:${error}, noDebug:${noDebug}, Javac:${noJavac} Time in millis:${sd}"

Run the above script(buildFile.groovy) using:


C:\>groovy -Ddebug=1true buildFile.groovy 2>nul
