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

mvn generate-sources

after modifying the speadl file.

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

<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">

Possible issues and resolutions¶

If Maven in Eclipse gives the following error:

Plugin execution not covered by lifecycle configuration: org.eclipse.xtext:xtext-maven-plugin:2.6.0:generate (execution: default, phase: generate-sources)

In the Overview view of the pom.xml file, click on the error and select the Quick Fix named:

Permanently mark goal generate in pom.xml as ignored.

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