Introduction

This tutorial shows how to build an existing Scout application using Maven Tycho. Therefore we use the Minicrm application as base.

Installation / Prerequisites

This tutorial assumes that your environment fulfills the following requirements.

Eclipse

Eclipse for Scout Developers Juno

Download-URL: http://www.eclipse.org/downloads/packages/eclipse-scout-developers/junor

m2eclipse

Updatesite-URL: http://download.eclipse.org/technology/m2e/releases

choose: m2e - Maven Integration for Eclipse	(1.1.0.20120530-0009)

Install m2e connectors: Window > Preferences > Maven > Discovery > Open Catalog

choose: Tycho Configurator

Optional: EGit

Updatesite-URL: http://download.eclipse.org/egit/updates

choose: Eclipse EGit	(2.0.0.201206130900-r)
        Eclipse JGit	(2.0.0.201206130900-r)

Maven

Installation guide: http://maven.apache.org/download.html#Installation

Part I - Maven Tycho Integration

1. Create new Eclipse Project (used as parent POM)
2. Generate POMs for existing projects / plug-ins
mvn org.eclipse.tycho:tycho-pomgenerator-plugin:generate-poms
    -DgroupId=org.eclipse.minicrm
    -Dversion=1.0.0-SNAPSHOT
    -DextraDirs==../org.eclipse.minicrm.client,../org.eclipse.minicrm.server,../org.eclipse.minicrm.shared,../org.eclipse.minicrm.ui.rap,../org.eclipse.minicrm.ui.swing,../org.eclipse.minicrm.ui.swt
3. Convert every project into a Maven Project: Configure > Convert to Maven Project...
4. [Optional] Resolve Warnings caused by the previous steps (see Problems-View)
  • Delete every bin directory and fix build.properties files (Cause: The project's output folder was changed from /bin to /target/classes)
  • Delete duplicate Maven Coordinates (groupId and version)
5. Extend parent POM configuration

6. Build parent POM
mvn clean package

Part II - Build Swing client (building an Eclipse Product)

1. Create new Eclipse Project (holding the client Product)
2. Add / Create Swing client Product
  • Important: Tycho only supports *.product file in the project root
  • Important: The *.product file has to contain the attribute 'uid' (correspond to the ID field in the Product Configurator view)
3. Create POM configuration
  • pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <version>2.5</version>
  <configuration>
	<encoding>UTF-8</encoding>

</assembly>
4. Convert to a Maven Project: Configure > Convert to Maven Project...
5. Update the parent POM
  • Extend the modules by the new Maven Module
6. Add WEB-INF template to match Equinox in a Servlet Container requirements (directory location has to match the referred fileSet in assembly.xml)
  • A running WEB-INF template can be extracted from Scout SDK exported war file. Details can be found here.
7. Build parent POM

Part IIII - Advanced stuff

integrate the JRE into the client zip

Extend the assembly.xml's fileSets definition

<!-- integrate the JRE into the client zip -->
<fileSet>
  <directory>/path/to/jre</directory>
  <outputDirectory>/${product.finalName}/jre</outputDirectory>
</fileSet>
