but the main problem is the gradle cannot find the tools.jar
step to fix it
1. copy all file in [your jdk installation folder]\lib\*.* to [your jre installation folder]\lib\ (i recommended to copy all not only "tools.jar"(who know it depent other library))
2. restart cmd
3. run your gradle task
and it maybe fixed
story how i solved it:
one day i run a minecraft forge gradle task and it results BUILD UNSUCCESFUL error an i read everything that show in the cmd from when i type the "gradlew build" command to the end and i find the main cause of the problem is the gradle cannot find the tools.jar(to find this i set screen buffer height to 9000 and width 167) and i have installed the java JDK and i think it maybe search in my JRE folder to test if this true i copy all files and folder in [jdk installation fold]\lib\*.* to [jre installation folder]\lib\ and it work and i post this to this forum
