Gradle build with Java 8

Question

I'm trying to build Java 8 project with Gradle 1.6, but I'm stuck on this error:

Execution failed for task ':ejb:compileJava'
invalid target release: 1.8

JAVA_HOME is set as "D:\Program Files\Java\jdk1.8.0", and build.gradle contains these lines:

sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8

Have you set the JAVA_HOME environment variable to the JDK8 install directory? — JB Nizet, Jul 24 '13 at 18:08
Have you tried `"1.8"` instead of `JavaVersion.VERSION_1_8`? — fge, Jul 24 '13 at 18:08
I just noticed that typing "java -version" prints out 1.7.0_25. So there must be something wrong with my java_home — perak, Jul 24 '13 at 18:16

Found the answer. I replaced JAVA_HOME

D:\Program Files\Java\jdk1.8.0

with

D:\Progra~2\Java\jdk1.8.0

and build succeeded.

Was your filesystem FAT32? Can't believe that I am seeing "Progra~1" in 2013. – lyomi Dec 17 '13 at 10:24

My filesystem is ntfs – perak Jan 11 '14 at 18:07
@perak I'm using this "C:\Program Files\Java\jdk1.8.0_45" Or even this "C:\Program Files (x86)\Java\jdk1.8.0_45" in JAVA_HOME, in both User variables and System variable in Environment Variables, But problem is still exist! – Dr.jacky May 16 '16 at 07:46
I am also facing the same problem. The JAVA_HOME is set to C:\Program Files\Java\jdk1.8.0_31 but still getting the error . Any solution? – worrynerd May 26 '17 at 21:27

I found picking wrong JAVA_HOME path value. After updating correct path, it's working for me. No need to do any change.
