Description Jesse Glick 2012-06-01 19:11:24 UTC
Revision 1236803 (in 1.8.3) added some JDK 8 support. Unfortunately running <javac> by default fails with this error:

  Class not found: javac1.8

Workaround is to pass -Dbuild.compiler=javac1.7.

Apache Ant(TM) version 1.9.2 compiled on July 8 2013

java.exe -version

I did an example which works for me.

Ant: 1.9.4
Java: 1.8.0-ea (I know, I should update ....)

Buildfile: C:\temp\ant-test\build.xml

    [mkdir] Created dir: C:\temp\ant-test\build\classes
