Thanks Steve, sounds very useful. These are my steps: tar xzvf ~/Downloads/lucene-4.1.0-src.tgz cd lucene-4.1.0 ant ant idea
This last step fails with: Buildfile: /Users/cbamford/projects/lucene-4.1.0/build.xml BUILD FAILED Target "idea" does not exist in the project "lucene". Total time: 0 seconds What have I done wrong? Thanks! - Chris -----Original Message----- From: Steve Rowe <sar...@gmail.com> To: java-user@lucene.apache.org Sent: Wed, 20 Feb 2013 16:29 Subject: Re: More questions on BlockJoinQuery Hi Chris, This mailing list is fine for discussing IntelliJ and Maven issues as they relate to Lucene. You'll need Ant v1.8.2+ to bootstrap things. 'ant idea' at the top level will produce an IntelliJ project you can open - see <http://wiki.apache.org/lucene-java/HowtoConfigureIntelliJ> for more info. For some treatment of Maven issues, see dev-tools/maven/README.maven.
