Ant: Class not found: javac1.8

Question

I am trying to build a project using Ant in eclipse. I right-clicked on build.xml > Run As > Ant Build. However, I am getting the following error:

BUILD FAILED
C         


        

Answer 1

To make it still more clear.

1>Set JAVA_HOME,JRE_HOME and Update Ant to 1.9

2>Over build.xml right click => run as (this takes into configuration)==>Now in this Edit Configuration and launch pop-up window

select Main tab then the third form field called "Arguments" add:

-Dbuild.compiler=javac1.7

3> In build.xml add includeantruntime="false"

It should compile without any message
