A small example to show how to configure a Maven build for an Xtext language and how to use it from Maven and Gradle.

If you use Xtext 2.9 or higher, the Maven build for your language is auto-generated. Just skip ahead to the usage section.

• see my.mavenized.herolanguage.* projects
• Language plug-ins, updatesite and Eclipse feature built via Maven/Tycho
• Xtext Code Generation (Language infrastructure generated from grammar)
• Xtend Code Generation

• example-project
• example-project-gradle
• Example Language (herolanguage) Code Generation
• Xtend Code Generation

Try it out!

   export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=256m"

 mvn clean install

 cd ../example-project/
 mvn clean install

 cd ../example-project-gradle/
 ./gradlew build

We now have automatic builds:

There is also a Maven Archetype available that automatically creates your new project based on this example: https://github.com/fuinorg/emt-xtext-archetype

The build will fail immediately because of version conflicts. A possible error might look similar to the following:

• No versions available for org.eclipse.emf:org.eclipse.emf.mwe2.runtime:jar:[2.9.1.201705291010] within specified range

Even if the specified version (see pom) is available on the central maven repository, updating related snapshots will most likely help the problem.

• mvn clean install -U
