错误：A SPI class of type org.apache.lucene.*** with name 'Whitespace' does not exist.

错误：java.lang.IllegalArgumentException: A SPI class of type org.apache.lucene.analysis.util.TokenizerFactory with name 'Whitespace' does not exist. You need to add the corresponding JAR file supporting this SPI to your classpath.
解决：把
C:\CHRUAN\workspace\solr-4.1.0\lucene\analysis\common\src\resources
也加到classpath中：<classpathentry kind="src" path="lucene/analysis/common/src/resources"/>
