Make Agents Yourself

h1. SpeADL MAY Maven SetUp

It is possible to use maven to generate code so that Eclipse is not needed anymore.

For example, one possible workflow is to use another IDE and executing <pre>mvn generate-sources</pre> after modifying the speadl file.

In order to do that, use the following POM file:

<pre>

<project ...>

	<modelVersion>4.0.0</modelVersion>

	<groupId>XXX</groupId>

	<artifactId>XXX</artifactId>

	<version>XXX</version>

	<properties>

h2. Possible Issues and Resolutions

h3. Errors in the POM file

If the POM file contains the following errors in Eclipse:

 Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-clean-plugin:2.5:clean (execution: default, phase: generate-sources)

and

 Plugin execution not covered by lifecycle configuration: org.eclipse.xtext:xtext-maven-plugin:2.6.2:generate (execution: default, phase: generate-sources)

When hovering on the error, choose the following quickfix:

 Permanently mark goal clean in pom.xml as ignored as ignored in Eclipse build.

and

 Permanently mark goal generate in pom.xml as ignored as ignored in Eclipse build.

This will prevent the Maven plugin in Eclipse to generate the source code while Eclipse also does it internally.
