解决方法：

方案一：

需要找到collection1/conf 目录下的solrconfig.xml文件，找到

<lib dir="../../../dist/" regex="solr-cell-\d.*\.jar" />

<lib dir="../../../contrib/clustering/lib/" regex=".*\.jar" />

<lib dir="../../../dist/" regex="solr-clustering-\d.*\.jar" />

<lib dir="../../../contrib/langid/lib/" regex=".*\.jar" />

<lib dir="../../../dist/" regex="solr-langid-\d.*\.jar" />

<lib dir="../../../contrib/velocity/lib" regex=".*\.jar" />

<lib dir="../../../dist/" regex="solr-velocity-\d.*\.jar" />

将其注释掉，然后到sorl源目录中找到相应的jar包添加到项目的lib文件夹中。

方案二：

复制solr-4.5.0\contrib和\solr-4.5.0\dist文件夹，到任意一个目录下。

在collection1/config目录中找到solrconfig.xml文件

修改solrconfig.xml配置文件，将dir目录配置成绝对路径（该路径就是刚刚复制的contrib和dist文件夹地址），根据自己的jar路径进行配置，如：
