Thanks Michael. I did add all the 4 modules to my classpath like this: java \ -cp $CWD/demo/build/classes/java/main:$CWD/analysis/common/build/classes/java/main:$CWD/queryparser/build/classes/java/main:$CWD/core/build/classes/java/main \ org.apache.lucene.demo.IndexFiles \ -docs $DOCS_DIR
but get this error: Indexing to directory 'index'... Exception in thread "main" java.lang.LinkageError: MemorySegmentIndexInputProvider is missing in Lucene JAR file at org.apache.lucene.store.MMapDirectory.lookupProvider(MMapDirectory.java:437) at java.base/java.security.AccessController.doPrivileged(AccessController.java:319) at org.apache.lucene.store.MMapDirectory.doPrivileged(MMapDirectory.java:395) at org.apache.lucene.store.MMapDirectory.<clinit>(MMapDirectory.java:445) at org.apache.lucene.store.FSDirectory.open(FSDirectory.java:161) at org.apache.lucene.store.FSDirectory.open(FSDirectory.java:156) at org.apache.lucene.demo.IndexFiles.main(IndexFiles.java:127) Caused by: java.lang.ClassNotFoundException: org.apache.lucene.store.MemorySegmentIndexInputProvider at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:526) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:534) at java.base/java.lang.Class.forName(Class.java:513) at java.base/java.lang.invoke.MethodHandles$Lookup.findClass(MethodHandles.java:2869) at org.apache.lucene.store.MMapDirectory.lookupProvider(MMapDirectory.java:422) ... 6 more the full classpath is usually very long as it will contain not only lucene but also all the 3rd party dependencies.
