How To Build a Custom Elasticsearch Adapter for Liferay

Requirements

• blade cli

Instruction for Linux Environment

1. Create a working folder
2. Go to working folder and run "blade init WORKSPACE_NAME" for example blade init elasticsearch-adapter-2.1.3-patched
3. Go to workspace folder and clone com-liferay-search from git: git clone https://github.com/liferay/com-liferay-portal-search.git
4. Find out the hash (commit id) for the adapter version you want to have by browsing com-liferay-elasticsearch/bnd.bnd history
5. Go to clone folder and switch to the commit version, for example git fetch origin 226300aa249dbe147303a15b77099396575124a3 and git reset --hard FETCH_HEAD
6. From the local clone, remove all the other project than com-portal-search-elasticsearch
7. Modify com-portal-search-elasticsearch build.gradle file (see below) for compiling to succeed. Thanks to Sampsa Sohlman for this:
8. Run ../../../gradlew clean build

That's it.
