copied!<p>Very good question! I am using the maven indexer to look up some artifacts. I am programmatically downloading the maven index from central and running queries on it. This is my method: </p> <pre><code>public IteratorSearchResponse executeGroupArtifactSearch(String group, String artifact) throws Exception { Query groupIdQ = indexer.constructQuery( MAVEN.GROUP_ID, new SourcedSearchExpression( group ) ); Query artifactIdQ = indexer.constructQuery( MAVEN.ARTIFACT_ID, new SourcedSearchExpression( artifact ) ); BooleanQuery query = new BooleanQuery(); query.add( groupIdQ , Occur.MUST ); query.add( artifactIdQ, Occur.MUST ); query.add( indexer.constructQuery( MAVEN.CLASSIFIER, new SourcedSearchExpression( Field.NOT_PRESENT ) ), Occur.MUST_NOT ); IteratorSearchRequest request = new IteratorSearchRequest( query, Collections.singletonList( centralContext ), null ); IteratorSearchResponse response = indexer.searchIterator( request ); return response; } </code></pre> <p>Since I updated to maven 3.1.0 and org.eclipse.aether I am getting this Exception: </p> <pre><code>Caused by: java.lang.ClassNotFoundException: org.sonatype.aether.version.InvalidVersionSpecificationException at org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy.loadClass(SelfFirstStrategy.java:50) at org.codehaus.plexus.classworlds.realm.ClassRealm.loadClass(ClassRealm.java:244) at org.codehaus.plexus.classworlds.realm.ClassRealm.loadClass(ClassRealm.java:230) ... 30 more </code></pre> <p>It seems that the 3.1.0 Maven Indexer still has some dependencies to org.sonatyep.aether. Curious enough that I get this Exception because "org.sonatype.aether.version.InvalidVersionSpecificationException" is still part of the project. </p> <p>So how do I resolve this? </p>

Querying!
