Question

Currently I’m working with Lucene 3.6 and am having difficulty getting IndexWriters to work.

The API documents suggest that:

IndexWriter writer = new IndexWriter(Directory, Analyzer);

(and a few other similar constructors)is depreciated and that I should use something like:

IndexWriter writer = new IndexWriter(Directory, Configuration);

However eclipse won’t recognize this newer constructor (lucene-core3.6.jar is added to the build path of my project) and if I use an older constructor I have to suppress a warning (which I don’t especially want to do – an exception gets thrown when I index in memory with these older methods).

I’ve cleaned the project, but the problem still persists.

EDIT: The code I am using:

        Directory index = new RAMDirectory();
    StandardAnalyzer analyzer = new StandardAnalyzer();
    IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_36, analyzer);
    IndexDeletionPolicy IndexDeletionPolicy = new KeepOnlyLastCommitDeletionPolicy();
    MaxFieldLength fieldLength = new MaxFieldLength(256);
    IndexWriter writer = new IndexWriter(index, analyzer, false, IndexDeletionPolicy, fieldLength);
    //IndexWriter writer = new IndexWriter(index, config); 
    writer.setUseCompoundFile(false);

Answer 1

I solved the problem:

There was a .jar file interfering with lucene (thirdparty-all.jar) which I found through looking at the stack trace. Removing the .jar removed problem.
