Error starting modern compiler encountered the following error when using ant1.7 in MyEclipse 6.5:

BUILD FAILED

Error starting modern compiler

The solution is to use your own jre1.6 instead of MyEclipse 6.5’s own JRE

In MyEclipse, click windows — > preferences–> Java–> Installed JREs–> Add new select the directory where JRE is located and add it successfully
