Getting java ClassNotFoundException for JavaScriptEngine

Question

I am getting java.lang.ClassNotFoundException: org.apache.bsf.engines.javascript.JavaScriptEngine when executing ant build-db-userprofile ( tutorial I'm following ).

Apparently this is caused when the BSF .jar is not present in $ANT_HOME/lib but when I execute ls -l $ANT_HOME/lib && ant -version I get the following:

-bash-4.1$ ls -l $ANT_HOME/lib

Apache Ant version 1.7.1 compiled on May 10 2016

Another possibility that has been mentioned is using JDK < 1.6, but I am using JDK 7.0_79. My ANT_HOME and ANT_OPTS env vars are set as following:

ANT_HOME=/usr/share/ant ANT_OPTS=-server -XX:MaxPermSize=256M -Xmx1000m -XX:+UseParallelGC -Xms1000m -XX:SoftRefLRUPolicyMSPerMB=1 -XX:MaxHeapFreeRatio=99

Answer 1

I fixed this by compiling and installing ant in my home directory. The issue probably happened because of the way the server I'm working on is set up, and the fact that I don't have admin privilege.
