-----------------------------
Summary: Updating from 7.X to 8.X breaks
Key: LUCENE-9129
URL: https://issues.apache.org/jira/browse/LUCENE-9129
Project: Lucene - Core
Issue Type: Bug
Reporter: xia0c
Hi, during my upgrading process from 7.X to 8.X I found another code break.
{code:java}
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.index.LeafReaderContext;
import org.apache.lucene.index.MultiDocValues;
import org.apache.lucene.index.SortedDocValues;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.Query;
import org.apache.lucene.search.SimpleCollector;
import org.apache.lucene.search.TopDocs;
import org.apache.lucene.util.LongValues;
import org.apache.solr.handler.component.FacetComponent.FacetContext;
import org.apache.solr.search.DocSet;
import org.apache.solr.search.DocSetUtil;
import org.apache.lucene.index.IndexReader;
public class TestLucene {
private FacetContext fcontext;
private DocSet docs;
private IndexReader reader;
public void demo() throws IOException {
DocSetUtil.collectSortedDocSet(docs, reader, new
SimpleCollector() {
@Override
public boolean needsScores() { return false; }
@Override
protected void doSetNextReader(LeafReaderContext ctx) throws
IOException {
// TODO
}
@Override
public void collect(int doc) throws IOException {
// TODO Auto-generated method stub
}
});
}
}
{code}
The code should pass before, but it throws an error:
{code:java}
[ERROR] /TestLucene.java:[32,82] <anonymous TestLucene$1> is not abstract and
does not override abstract method scoreMode() in
org.apache.lucene.search.Collector
[ERROR] /TestLucene.java:[36,19] method does not override or implement a method
from a supertype
{code}
I try to find changes in the migration
guide(https://github.com/apache/lucene-solr/blob/branch_8x/lucene/MIGRATE.txt)
but I didn't find it.
