Hi Harish > Unsupported major.minor version 51.0
This indicates that your environment does use a Java version < 1.7. Also that it fails on an LDPath related module fits as Apache Marmotta LDPath requires Java 1.7 You should check that maven is using Java 7 on your system. If java -version does report 1.7 maybe you do have some maven specific configurations in place? best Rupert On Sat, May 31, 2014 at 12:25 AM, harish suvarna <hsuva...@gmail.com> wrote: > Thanks Antonio.
