Build

To build that package, you need a working installation of maven (version 3.3.x) and JDK 8 or up.

First, clone the repository and build the plugin:

git clone https://github.com/Normation/rudder-plugin-datasources.git
cd rudder-plugin-datasources
git checkout 4.1-0.2
mvn clean package
.......
  [INFO] Building jar: /home/fanf/java/workspaces/rudder-project/rudder-plugin-datasources/target/datasources-4.1-0.2-plugin-with-own-dependencies.jar

To proceed to installation, you will need that jar and file "src/main/resources/datasource-schema.sql".

Installation

Install the plugin by copying the jar in /opt/rudder/share/rudder-plugins/ on your Rudder root server and the file datasource-schema.sql, then execute:

# Copy the plugin in Rudder plugin directory
scp or whatever datasources-4.1-0.2-plugin-with-own-dependencies.jar into /opt/rudder/share/rudder-plugins/

# create table for Rudder data sources plugin:
# note that if you installed Rudder 4.1~alpha or 4.1~beta1, or a previous version
# of the plugin, you can skip that step (which would fail with a "table exists" error)
psql -U rudder -h localhost -d rudder -f /path/to/datasource-schema.sql

# declare plugin use 
#note: 
# - the plugin must be in /opt/rudder/share/rudder-plugins/
# - the command parameter is the file name without ".jar"
/opt/rudder/bin/rudder-plugin register datasources-4.1-0.2-plugin-with-own-dependencies

# then restart Rudder:
