Hi André,
If you are building the frameworks as described here:
http://wiki.wocommunity.org/display/documentation/Building+and+Installing+a+Framework+with+Ant
<http://wiki.wocommunity.org/display/documentation/Building+and+Installing+a+Framework+with+Ant>
You need to check the version of java the console is using with:
java -version
If it returns something like:
java version “1.8.0_66"
then change it by editing bash_profile:
vi ~/.bash_profile
and setting:
export JAVA_HOME=`/usr/libexec/java_home -v 1.7`
before building.
I deploy some projects on java 1.7 and others on java 1.8 so I rebuild my
frameworks often.
Steve
