groovy - Issues in passing extra properties to a gradle task -


i having trouble in passing properties gradle task. here build file

buildscript {     repositories { }   ext {     dir = '' }  apply plugin: 'java' apply plugin: 'maven' apply plugin: 'groovy'  group = 'group' version = 'version'  sourcecompatibility = 1.8 targetcompatibility = 1.8  task wrapper(type: wrapper) {     gradleversion = '3.4' }  repositories {  } dependencies {     compile gradleapi()     compile localgroovy()  }

as can see, have property dir initialized ''. now, here task

class mytask extends defaulttask {     file mydir = project.dir      @taskaction     public void action() {     } }

my plugin

class myplugin implements plugin<project> {     @override     def void apply(project project) {         project.tasks.create("mytask", mytask)     }  }

and unit test

public class testplugin {     @test     public void testplugin() {         project project = projectbuilder.builder().build();         project.getplugins().apply(testplugin.class);         assert.asserttrue(project.getproject().gettasks().findbyname("mytask") instanceof mytask);     } }

now when run test, shows error couldn't find dir property.

caused by: groovy.lang.missingpropertyexception

am missing something?

your build.gradle script , test not linked in way. in test, create clean new project , first (and only) thing apply custom plugin, creates custom task. task property mydir going set, called property dir not exist in project, exception thrown.

you can either define property dir test project ...

project project = projectbuilder.builder().build(); project.ext.dir = '' project.getplugins().apply(testplugin.class); assert.asserttrue(project.getproject().gettasks().findbyname("mytask") instanceof mytask);

... or apply new plugin project of build.gradle script (when done).
