curl - Failed executing gradlew using PHP exec through browser -

i want run gradlew using php. have tried using exec(), shell_exec, or passthru. executed commands inside php script named "build.php". tried calling script browser or curl , got error

exception in thread "main" java.lang.runtimeexception: java.io.filenotfoundexception: /var/www/.gradle/wrapper/dists/gradle-2.2.1-all/6dibv5rcnnqlfbq9klf8imrndn/gradle-2.2.1-all.zip.lck (no such file or directory) 

however when called command line using php build.php, worked well.

i need gradlew command executed through user action browser. question: might cause error , how rid of it?

thank much.

that's because don't have folder named .gradle in /var/www create folder , give a+rw permissions:

mkdir /var/www/.gradle chmod a+rw /var/www/.gradle
