Hi, You need a properly configured Java 1.7 compiler to build and run the software. On OSX, this can be a bit confusing. You may have installed Java 1.7 but the default system copy of Java 1.6 is still found by Maven. You should be able to setup the JAVA_HOME variable in your environment in order to fix this problem: export JAVA_HOME=$(/usr/libexec/java_home -v 1.7) On my Mac, this resolves to the following: /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home The exact directory will depend on which JDK version you have installed. If you do not have Java 1.7 at all, then go here: http://java.com/en/download/mac_download.jsp?locale=en Install the DMG file and then setup your environment as above…then it should work. —Jeremy On Dec 18, 2013, at 1:58 AM, Luca Colaneri <[log in to unmask]<mailto:[log in to unmask]>> wrote: Hi Jeremy, I commented the lines as you suggested and the installation went through, but when testing the installation with the command suggested on the WIKI java -jar ./distribution/hps-distribution-3.0-SNAPSHOT-bin.jar (by the way, the jar file is in the "target" folder under distribution) I get the errors you can see in the attached screenshot. How can we fix it?
