i have tried many suggested options such adding --rerun-tasks script parameters, uncheck "use in-process build" option in compiler -> gradle settings of android studio etc..but none of them have worked.

here sample of build.gradle dependency list:

dependencies {     compile filetree(dir: 'libs', include: ['*.jar'])     compile ('com.android.support:appcompat-v7:18.0.0'){         force = true     }     compile ('com.android.support:mediarouter-v7:18.0.0'){         force = true     }     compile 'com.google.android.gms:play-services:6.5.87'      testcompile 'junit:junit:4.12'      testcompile 'com.github.tomakehurst:wiremock:1.46'      testcompile 'org.bouncycastle:bcprov-jdk15on:1.50'      testcompile ('org.robolectric:robolectric:3.0-rc3'){         exclude group: 'commons-logging', module: 'commons-logging'         exclude group: 'org.apache.httpcomponents', module: 'httpclient'     }     testcompile 'org.robolectric:shadows-support-v4:3.0'     testcompile 'org.robolectric:shadows-httpclient:3.0'     testcompile 'org.robolectric:shadows-maps:3.0' } 

have spent many hours looking in no result. highly appreciate in regard.

thanks!
