java - Intellij Idea 15 Gradle project import Junit compile errors -

i having issue simple project's junit in intellij idea.

gradle (2.10) can run junits command line. import project intellij idea 15.0.3, try run junit in intellij throws compile errors if junit not on classpath. error:(1, 17) java: package org.junit not exist

checked project structure junit lib there, tried other method adivised - create test in intellij 'goto test > create new test >' still not luck.

build.gradle:

allprojects {     apply plugin: 'idea'     apply plugin: 'java'      sourcecompatibility = 1.7     group 'junit.fail'     version '1.0'      repositories {     mavencentral()     } }  subprojects {     dependencies {     testcompile 'junit:junit:4.12'     } }  dependencies {     compile project(':common')     compile project(':moda') } 

settings.gradle

rootproject.name = 'junit-fail' include 'common' include 'moda' 

simple code in module common

junit-fail\common\src\main\java

public class classa {     public string geta() {         return "a";     } } 

junit-fail\common\src\test\java

import org.junit.test; import static org.junit.assert.*;  public class classatest {     @test     public void testgeta() throws exception {         classa = new classa();         assertequals("a", a.geta());     } } 

moda can have similar test code.

able resolve issue moving .gradle c:\users\ c:\dev jdk8 ok jdk7 never worked - home dir network synced. may have been issue.
