Scout/Tutorial/3.8/Maven Tycho Build

Introduction

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

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/releases/juno (or http://download.eclipse.org/technology/m2e/releases)

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

Old version
Version 1.1.0 is not the current version. Therefore you might need to uncheck "Show only the latest versions of available software" to see this version in the list.

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

choose: Tycho Configurator

Optional: EGit

Updatesite-URL: http://download.eclipse.org/releases/juno (or 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

Sample pom.xml:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>org.eclipse.scout.autotest</groupId>
    <artifactId>org.eclipse.scout.autotest</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../org.eclipse.scout.autotest.parent/</relativePath>
  </parent>
  <artifactId>org.eclipse.scout.autotest.client</artifactId>
  <packaging>eclipse-plugin</packaging>
</project>

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

Add Eclipse and RAP platform Repositories (using Maven Profiles)

<profiles>
  <profile>
    <id>platform-juno</id>
    <activation>
      <activeByDefault>true</activeByDefault>
      <property>
        <name>platform-version-name</name>
        <value>juno</value>
      </property>
    </activation>
    <properties>
      <eclipse.repo.url>http://download.eclipse.org/releases/juno</eclipse.repo.url>
      <rap.repo.url>http://download.eclipse.org/rt/rap/1.5/runtime</rap.repo.url>
      <platform.version>[3.8,3.9)</platform.version>
      <tycho.version>0.15.0</tycho.version>
    </properties>
  </profile>
</profiles>
 
<repositories>
  <repository>
    <id>eclipse platform</id>
    <url>${eclipse.repo.url}</url>
    <layout>p2</layout>
  </repository>
  <repository>
    <id>rap platform</id>
    <url>${rap.repo.url}</url>
    <layout>p2</layout>
  </repository>
</repositories>

Replace existing Build settings

<build>
  <plugins>
    <plugin>
      <groupId>org.eclipse.tycho</groupId>
      <artifactId>tycho-maven-plugin</artifactId>
      <version>${tycho.version}</version>

          </environment>
        </environments>
      </configuration>

        <configuration>
          <filters>
            <!-- work around Equinox bug 348045 -->
            <filter>
              <type>p2-installable-unit</type>
              <id>org.eclipse.equinox.servletbridge.extensionbundle</id>
              <removeAll />
            </filter>
          </filters>
        </configuration>
      </plugin>
    </plugins>
  </pluginManagement>
</build>

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

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 a Scout SDK exported war file. Details can be found here.

7. Build parent POM

Part IIII - Advanced stuff
