groovy - Execute String as Code in Jenkins Pipeline -


i want execute multiple parallel steps in jenkins pipeline. variables need given through arraylists. want build code via string builder , loop. after want execute string code

pseudocode:

sb << try{ \n  for(i=0; i<tmp; i++) {     sb <<     parallel(      build variable{         def buildjobname = build job: buildjobvariable, parameters:                 [                       string(name: 'parametername', value: parameter)                 ]     } }  sb << catch(e){  (...) }

but how able execute this? tried groovyshell.evaluate(sb.tostring()) results in following error:

hudson.remoting.proxyexception: groovy.lang.missingmethodexception: no signature of method: java.lang.class.evaluate() applicable argument types: (java.lang.string)

we use groovy hash define parallel steps , execute them in 1 parallel statement:

def tests = ["test1", "test2", "test3", "test4"];  try {     def branches = [:];     (int = 0; < tests.size(); i++) {         def test = tests[i];         branches["$test"] = {             try             {                 env.test = test;                 build job: 'build_job', parameters: [string(name: 'name', value: test)]             }             catch (err)             {                 currentbuild.result = 'failure';             }         }     }      parallel branches }

each element in branches hash 1 parallel execution path.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
