The scripts that you find in the bin directory are configured to be used with installation of elasticsearch (not the source code directory). For example, these script assume that the elasticsearch jars will be in the lib directory. If you want to use scripts to install plugins, simply build elasticsearch package (mvn package -DskipTests=true) and unzip the the elasticsearch package (target/releases/elasticsearch-0.21.0.Beta1-SNAPSHOT.zip) to some other directory. Then you will be able to use scripts there. On Tuesday, January 15, 2013 7:13:08 AM UTC-5, Yann Barraud wrote: > Hello, > > Just built ES from today's Master branch.
