Question

一旦我啓動Eclipse告訴他哪裏Solr的是通過

`-Dsolr.home=D:\devel\apps\solr-4.3.1_master\ec2` 

開始SOLR但出現以下異常。

我在Solr的新手，我有點失去了關於這個話題。有沒有人看任何可能幫助我解決問題的東西。

在此先感謝

好的。我發現了這個問題。問題是我拷貝了solr/lib文件夾中的'lucene-analyers-icu-4.3.1.jar'和'lucene-analysers-smartcn-4.3.1.jar'，並且在Apache Tomcat/lib文件夾，所以他們崩潰。我刪除了那些在tomcat中的。
