问题
as i said in the title: i am using Java, but when I run the code on Eclipse, i get the following error..
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/lucene/analysis/util/ResourceLoader at Indexer.getIndexWriter(Indexer.java:38) at Indexer.rebuildIndexes(Indexer.java:73) at SolrIndexer.main(SolrIndexer.java:23) Caused by: java.lang.ClassNotFoundException: org.apache.lucene.analysis.util.ResourceLoader at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 3 more
The SAD PART: the class org.apache.lucene.analysis.util.ResourceLoader is not available in Lucene 4.0/3.6/4.0-ALPHA. although, there are a few webpages where people are talking about the resourceloader class.
can anyone help me out here? Any help would be appreciated..

The common analysers have been move lucene-analyzers-common-X.X.X.jar as a result of LUCENE-2510
Ensure that you have it in your classpath.

Looks like this class: org.apache.lucene.analysis.util.ResourceLoader cannot be found. Are you sure that all your required 3rd party libraries are on your class path?
According to this API URL, it seems that the interface is available 4.0.0-Alpha. Maybe you could try to revert to this version and see if it works?
