365 [Thread-11] ERROR backtype.storm.event - Error when processing event backtype.storm.daemon.supervisor$fn__3567$exec_fn__945__auto____3568$this__3668@5f775831 java.io.FileNotFoundException: Source 'file:/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/lib/ant-javafx.jar!/resources' does not exist at org.apache.commons.io.FileUtils.copyDirectory(FileUtils.java:866) at org.apache.commons.io.FileUtils.copyDirectory(FileUtils.java:770) at org.apache.commons.io.FileUtils.copyDirectory(FileUtils.java:745) at backtype.storm.daemon.supervisor$fn__3785.invoke(supervisor.clj:394) at clojure.lang.MultiFn.invoke(MultiFn.java:171) at backtype.storm.daemon.supervisor$fn__3567$exec_fn__945__auto____3568$this__3668.invoke(supervisor.clj:263) at backtype.storm.event$event_manager$fn__2068$fn__2069.invoke(event.clj:25) at backtype.storm.event$event_manager$fn__2068.invoke(event.clj:22) at clojure.lang.AFn.run(AFn.java:24) at java.lang.Thread.run(Thread.java:745)

问题解决，如下：

先不要执行
mvn exec:java -Dexec.mainClass="TopologyMain" -Dexec.args="src/main/resources/words.txt"
先执行
mvn -f pom.xml clean install
此时注意，这个工程里面的代码是有错误的，大概有三处，改正后就能编译通过了
install通过后再执行
mvn exec:java -Dexec.mainClass="TopologyMain" -Dexec.args="src/main/resources/words.txt"
