build - How to make up-to-date check notice non-file arguments in a Gradle Task? -

-

suppose have task class mytask reads input file, conversion on , writes output file (build.gradle):

class mytask extends defaulttask {     @inputfile file input     @outputfile file output     string conversion      @taskaction void generate() {         def content = input.text         switch (conversion) {             case "lower":                 content = content.tolowercase()                 break;             case "upper":                 content = content.touppercase()                 break;         }         output.write content     } }  project.task(type: mytask, "mytask") {     description = "convert input output based on conversion"     input = file('input.txt')     output = file('output.txt')     conversion = "upper" }

now works fine, when change input.txt or remove output.txt in file system executes again. problem it doesn't execute if change "upper" "lower", wrong.

i can't (don't want to) put build.gradle in inputs list because hack, wouldn't work if, say, command line argument changes gets mytask.conversion field. 1 thought of write value file in setconversion() method , put on inputs list, again, that's hack.

how can make gradle notice change official way? if know can read more this, don't hold on links ;)

i read more tasks , writing custom plugins, gave me no clue.

not sure if it's helpful i'd try:

class mytask extends defaulttask {     @inputfile file input     @outputfile file output     string conversion      @taskaction void generate() {         def content = input.text         switch (conversion) {             case "lower":                 content = content.tolowercase()                 break;             case "upper":                 content = content.touppercase()                 break;         }         output.write content     }      void setconversion(string conversion) {        this.inputs.property('conversion', conversion)        this.conversion = conversion     } }

could please check it?

c# - Where does the .ToList() go in LINQ query result -

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
