Elasticsearch 2.3.4 is not supported

[spider-network]

Plugin [decompound] is incompatible with Elasticsearch [2.3.4]. Was designed for version [2.3.3]

A plugin system that need a re-release of plugins every version is a not, what a plugin system was made for. 😄

Plugin version 2.3.4.0 for Elasticsearch 2.3.4 just released.

Except the download link is broken 👎

Sorry for the inconvenience, now I pushed the binary plugin zip.

Wanted to try this plugin out, but there is the same problem with 2.3.5 😅

In case anyone else needs this plugin for a specific version of Elasticsearch: it is actually quite easy to compile.

Here is what I did on Ubuntu 16.04 (adapt to your own case).

1. ensure you have the JDK :
   sudo apt-get install openjdk-8-jdk
2. ensure you have the right Java selected (you need Java 8):
   sudo update-alternatives --config java
3. clone
   git clone https://github.com/jprante/elasticsearch-analysis-decompound.git
4. edit version number
   cd elasticsearch-analysis-decompound
git checkout <branch that is close to your version, e.g. 2.4.1.0>
   and edit build.gradle (indicate the right version for elasticsearch)
5. compile
   ./gradlew assemble

The zip is in build/distributions/elasticsearch-analysis-decompound--plugin.zip.
Install and restart the node, in my case:

cd /usr/share/elasticsearch
bin/plugin install file:///path/to/elasticsearch-analysis-decompound/build/distributions/elasticsearch-analysis-decompound-2.4.4.0-plugin.zip
sudo service elasticsearch restart
