It's been requested a few times, so here is a complete guite to build Knowage from source code. A copy will be added to the root of the project as well.

Building Knowage from Source Code

Prerequisites

Before you begin, make sure you have the following installed:

Tool	Required Version
JDK	17 (LTS)
Maven	3.x
Node.js	≥ 22
Grunt CLI	latest (global)

The Java version is defined directly in the project's pom.xml: both maven.compiler.source and maven.compiler.target are set to 17. Make sure you have JDK 17 installed — not 11, not 21.

Add the paths of java, node, and npm to your system's PATH environment variable.

Install the Grunt CLI globally via npm:

npm install -g grunt-cli

Quick check before building:

java -version    # should show openjdk 17.x.x or similar
mvn -version     # should show Apache Maven 3.x.x
node -version    # should show v22.x.x or higher
grunt --version  # should show grunt-cli v...

1. Clone the Repository

git clone https://github.com/KnowageLabs/Knowage-Server.git
cd Knowage-Server

2. Build

The main project is knowage-ce-parent. From within that directory, run:

cd knowage-ce-parent
mvn clean install

3. Output

Once the build completes, the WAR files can be found at the following paths:

Module	Path
Core	`knowage/target/knowage.war`
API	`knowage-api/target/knowage-api.war`
Vue frontend	`knowage-vue/target/knowage-vue.war`
BIRT engine	`knowagebirtreportengine/target/knowagebirtreportengine.war`
Cockpit engine	`knowagecockpitengine/target/knowagecockpitengine.war`
Jasper engine	`knowagejasperreportengine/target/knowagejasperreportengine.war`
KPI engine	`knowagekpiengine/target/knowagekpiengine.war`
Meta	`knowagemeta/target/knowagemeta.war`
QBE engine	`knowageqbeengine/target/knowageqbeengine.war`
Talend engine	`knowagetalendengine/target/knowagetalendengine.war`

4. Python Module

There is no need to build the Knowage-Python module: just take the source code and run it as a standalone program. Refer to the official documentation for details.

5. Deploy

Once you have the WAR files, deploy them to an Apache Tomcat instance configured with a metadata database (MySQL/MariaDB or PostgreSQL). Refer to the manual installation guide for Tomcat configuration details. The database DDL scripts are located under knowagedatabasescripts/<dbms>/.
