獲取Java ClassNotFoundException for JavaScriptEngine

執行ant build-db-userprofile（tutorial I'm following）時，我得到java.lang.ClassNotFoundException: org.apache.bsf.engines.javascript.JavaScriptEngine。獲取Java ClassNotFoundException for JavaScriptEngine

顯然，當BSF的.jar不存在於這個$ANT_HOME/lib造成但是當我執行ls -l $ANT_HOME/lib && ant -version我得到如下：

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

Apache Ant version 1.7.1 compiled on May 10 2016

已使用JDK 1.6 <提到的另一種可能性，但我使用JDK 7.0_79。我ANT_HOME和ANT_OPTS ENV瓦爾設置如下：

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

該軟鏈接是活動還是中斷？ –

@BhargavKumarR對不起，我沒有關注/理解這個問題。 – player87

ant-apache-bsf.jar - > ../../java/ant/ant-apache-bsf.jar該路徑是否有效？ –

我通過編寫和我的主目錄安裝防固定這一點。這個問題可能是由於我正在設置的服務器的設置方式以及我沒有管理員權限的事實而發生的。
