Hi all,
this problem is still present in rev 4.9 

eclipse.buildId=4.9.0.I20180906-0745
java.version=1.8.0_65
java.vendor=Oracle Corporation
BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=it_IT

Could you tell me how work around this?

Thanks in advance

Davide

Hi,

I've moved to version 4.7.3a (https://www.eclipse.org/downloads/packages/release/oxygen/3a)

Regards
Daniel

Hi Daniel,
I RESOLVE. It works also with the last version 4.9. You have to change the Ant JRE from Java7 to Java8.

Right click on XML ant file -> Run As.. -> Select JRE TAB -> Change Java7 to Java8

However, it's a workaround.

Regards

Davide

If you want to use Java 7, you can change the Ant Home to an older Ant version after downloading from Ant site.
