es-downloader

A simple tool written in Java to download documents from Elastic Search.

Building

Build standalone jar

mvn clean assembly:assembly

To build an executable, combine the standalone jar built from above with the stub bash script like so:

cd bin
rm es-downloader
cat stub.sh ../target/es-downloader-0.0.1-SNAPSHOT-jar-with-dependencies.jar > es-downloader
chmod +x es-downloader

The resulting es-downloader file can be executed from the command line
