我正在尝试使用solr4（trunk nightly build）使用clojure-solr-0.2.0。我遇到以下异常：
Caused by: java.lang.RuntimeException: Invalid version or the data in not in 'javabin' format
at org.apache.solr.common.util.JavaBinCodec.unmarshal(JavaBinCodec.java:99)
at org.apache.solr.client.solrj.impl.BinaryResponseParser.processResponse(BinaryResponseParser.java:39)

at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:243)
at org.apache.solr.client.solrj.request.QueryRequest.process(QueryRequest.java:89)
我假设这是因为clojure-solr正在使用某些版本的solrj库来自solr3代码库，而javabin格式在版本之间发生了变化。
是否有一些简单的方法可以让它发挥作用？
编辑：
我从项目的lib文件夹中删除了solrj，并将其替换为lib/apache-solr-solrj-4.0-2012-05-15_08-20-37.jar。我希望这可以工作，因为在运行时在类路径上找到相同的类（应该）（只有在运行lein deps来获取依赖关系时才需要传递依赖（或者我推理）。结果是在运行时找不到的类：

问题是jar中不再存在CommonsHttpSolrServer：
$ jar tf lib/apache-solr-solrj-4.0-2012-05-15_08-20-37.jar |grep Http

您很可能需要自己构建clojure-solr并修复它以使用最新的solr4。这实际上并不那么难。
