[SOLVED][1.9.4]Can't export a Java8 project

[JimiIT92]

The source of the mod is compiled in Java 8 (to allow lambda expressions in the GrassColourHandler), but when exporting it says that the mod cannot be exported in Java 8. This is the console error

How can i solve it?

Its right there in the error:

"lambda expression sare not supported in -source 1.6"

 

You aren't compiling for Java 8, you're compiling for Java 6.

So how can i compile in Java 8? In Eclipse the project is using Java 8, infact it gives me no error on there

 

EIDT: turns out i had to add these lines to the build.gradle file

sourceCompatibility = 1.7
targetCompatibility = 1.7

If you want to compile with Java 8, you have to set the source and target compatibility version as 1.8, not 1.7.

Yes, i've changed to this

sourceCompatibility = 1.8
targetCompatibility = 1.8

and it worked
