Hi, this happened probably due to an upgrade of the Jenkins machines to provide Ant 1.10: - our build is configured to use the latest Ant version - but Ant 1.10 requires Java 8
I've configured build jobs to use Ant 1.9.9 for now, I hope the build now succeeds... If the upgrade to Java 8 is done (NUTCH-2171), we should not forget to change both Java and Ant version.
