== Debug Messages ==
 +
Debug messages in Maven can be activated with a "-X" at the end of your maven command. For example to have the debug message of the clean operation, switch "mvn clean" to this "mvn clean -X".
 +
 +
== Maven Hosting ==
 +
The Acceleo artifacts and their stand alone dependencies are now hosted on repo.eclipse.org
 +
 +
== Releases Notes ==
 +
=== 2014/01/20 ===
 +
* The Acceleo artifacts are now hosted on repo.eclipse.org along with the maven plugin. They are now built as part of the Acceleo nightly build.
 +
* The artifactId of the maven plugin has been modified to org.eclipse.acceleo.maven to match all the other Acceleo artifacts
 +
* The hosting on raw.github.com is now deprecated!
 +
 +
===2012/09/7===
 +
* Fixing the possible ClassCastException with multiple generators built in a single maven build.
 +
* The build will now fail if there are errors.
 +
* A new property has been introduced to deactivate the failure on error. (<failOnError>false</failOnError>)
 +
 +
===2012/07/09===
 +
* The meta-model can now be resolved from the compilation dependencies and not only from the runtime dependencies. You can have the meta-model in a dependency resolved by Tycho and not only in one resolved by Maven
 +
* Improved debug messages
 +
 +
===2012/06/25===
 +
* Fix a bug for Mac OS X and Linux support of the build with dependencies inside jars
 +
* Improved debug messages
 +
 +
===2012/05/20===
 +
* First release
 +
 +
== Configuration ==
 +
The Acceleo maven plugin uses a configuration block to find the information about the project that should be compiled. Here is an example of this configuration for an UML generator.
 +
  <configuration>
 +
    <useBinaryResources>false</useBinaryResources>
 +
    <usePlatformResourcePath>true</usePlatformResourcePath>
 +
    <acceleoProject>
 +
      <root>${project.basedir}</root>
 +
      <entries>
 +
        <entry>
 +
          <input>src/main/java</input>
 +
          <output>target/classes</output>
 +
        </entry>
 +
      </entries>
 +
      <jars>
 +
        <jar>p2.eclipse-plugin:org.obeonetwork.pim.uml2.gen.java</jar>
 +
      </jars>
 +
    </acceleoProject>
 +
    <packagesToRegister>
 +
      <packageToRegister>org.eclipse.uml2.uml.UMLPackage</packageToRegister>
 +
    </packagesToRegister>
 +
    <uriHandler>org.eclipse.acceleo.maven.AcceleoURIHandler</uriHandler>
 +
    <failOnError>false</failOnError>
 +
  </configuration>
 +
 +
* <span style="font-weight:bold">useBinaryResource</span> - indicate that the advanced serialization should be used. The compiled modules produced are smaller but they are not as powerful to support complex URI use case (dynamic meta-models for example). This option should be at "false" by default.
 +
* <span style="font-weight:bold">usePlatformResourcePath</span> - indicate that absolute paths should be converted to "platform:/" relative paths. This option should be at "true" by default.
 +
* <span style="font-weight:bold">root</span> - The root of the project
 +
* <span style="font-weight:bold">entries</span> - Classpath entries for example "src" as the input and "bin" as the output.
 +
* <span style="font-weight:bold">jars</span> - The dependencies of the generator. Those dependencies can be defined using one of the following conventions
 +
** <span style="font-weight:bold">${project.basedir}\lib\myJar.jar</span> - A jar file located in the project.
 +
** <span style="font-weight:bold">p2.eclipse-plugin:org.eclipse.acceleo.anotherGenerator</span> - Another generator resolved thanks to Tycho.
 +
** <span style="font-weight:bold">p2.eclipse-plugin:org.eclipse.acceleo.anotherGenerator:1.0.0</span> - Another generator resolved thanks to Tycho limited to a specific version.
 +
** <span style="font-weight:bold">org.eclipse.acceleo:org.eclipse.acceleo.anotherGenerator</span> - Another generator resolved by maven.
 +
** <span style="font-weight:bold">org.eclipse.acceleo:org.eclipse.acceleo.anotherGenerator:1.0.0</span> - Another generator resolved by maven limited to a specific version.
 +
** <span style="font-weight:bold">org.eclipse.acceleo.anotherGenerator</span> - Another generator defined as a maven dependency.
 +
** <span style="font-weight:bold">org.eclipse.acceleo.anotherGenerator:1.0.0</span> - Another generator defined as a maven dependency with a restriction on a specific version.
 +
** <span style="font-weight:bold">C:\Users\MyName\...\myJar.jar</span> - The absolute path of a jar file.
 +
* <span style="font-weight:bold">packagesToRegister</span> - The name of the Java class that should be used to register the package on which the generation is launched.
 +
* <span style="font-weight:bold">uriHandler</span> - An AcceleoURIHandler used to convert the URI of the dependencies (if you want a different behavior than the usePlatformResourcePath). The default URI handler provided (org.eclipse.acceleo.maven.AcceleoURIHandler), does the same job as the option usePlatformResourcePath.
 +
* <span style="font-weight:bold">failOnError</span> - Indicates if the compilation should fail if errors are found (true by default).

== Plugin Management (parent and children pom.xml) ==
 +
In order to support a complex maven architecture with a parent pom.xml and children pom.xml, you should declare in the parent pom.xml the following code
 +
  <build><span style="color:#1B9AF7">
 +
    <pluginManagement>
 +
      <plugins>
 +
        <plugin>

It happens sometimes with complex dependencies between generators during a same build (if in the same build, you are building the metamodel and the generators), it should work anyway. Building the meta-model separately and resolving it with a Tycho based dependency and the location of the update site of the meta-model seems to fix this issue.

This issue should be fixed in the latest release.

Maven Integration

Debug Messages

Debug messages in Maven can be activated with a "-X" at the end of your maven command. For example to have the debug message of the clean operation, switch "mvn clean" to this "mvn clean -X".

Maven Hosting

The Acceleo artifacts and their stand alone dependencies are now hosted on repo.eclipse.org

Releases Notes

2014/01/20

  • The Acceleo artifacts are now hosted on repo.eclipse.org along with the maven plugin. They are now built as part of the Acceleo nightly build.
  • The artifactId of the maven plugin has been modified to org.eclipse.acceleo.maven to match all the other Acceleo artifacts
  • The hosting on raw.github.com is now deprecated!

2012/09/7

  • Fixing the possible ClassCastException with multiple generators built in a single maven build.
  • The build will now fail if there are errors.
  • A new property has been introduced to deactivate the failure on error. (<failOnError>false</failOnError>)

2012/07/09

  • The meta-model can now be resolved from the compilation dependencies and not only from the runtime dependencies. You can have the meta-model in a dependency resolved by Tycho and not only in one resolved by Maven
  • Improved debug messages

2012/06/25

  • Fix a bug for Mac OS X and Linux support of the build with dependencies inside jars
  • Improved debug messages

2012/05/20

  • First release

Configuration

The Acceleo maven plugin uses a configuration block to find the information about the project that should be compiled. Here is an example of this configuration for an UML generator.

 <configuration>
   <useBinaryResources>false</useBinaryResources>
   <usePlatformResourcePath>true</usePlatformResourcePath>
   <acceleoProject>
     <root>${project.basedir}</root>
     <entries>
       <entry>
         <input>src/main/java</input>
         <output>target/classes</output>
       </entry>
     </entries>
     <jars>
       <jar>p2.eclipse-plugin:org.obeonetwork.pim.uml2.gen.java</jar>
     </jars>
   </acceleoProject>
   <packagesToRegister>
     <packageToRegister>org.eclipse.uml2.uml.UMLPackage</packageToRegister>
   </packagesToRegister>
   <uriHandler>org.eclipse.acceleo.maven.AcceleoURIHandler</uriHandler>
   <failOnError>false</failOnError>
 </configuration>
  • useBinaryResource - indicate that the advanced serialization should be used. The compiled modules produced are smaller but they are not as powerful to support complex URI use case (dynamic meta-models for example). This option should be at "false" by default.
  • usePlatformResourcePath - indicate that absolute paths should be converted to "platform:/" relative paths. This option should be at "true" by default.
  • root - The root of the project
  • entries - Classpath entries for example "src" as the input and "bin" as the output.
  • jars - The dependencies of the generator. Those dependencies can be defined using one of the following conventions
    • ${project.basedir}\lib\myJar.jar - A jar file located in the project.
    • p2.eclipse-plugin:org.eclipse.acceleo.anotherGenerator - Another generator resolved thanks to Tycho.
    • p2.eclipse-plugin:org.eclipse.acceleo.anotherGenerator:1.0.0 - Another generator resolved thanks to Tycho limited to a specific version.
    • org.eclipse.acceleo:org.eclipse.acceleo.anotherGenerator - Another generator resolved by maven.
    • org.eclipse.acceleo:org.eclipse.acceleo.anotherGenerator:1.0.0 - Another generator resolved by maven limited to a specific version.
    • org.eclipse.acceleo.anotherGenerator - Another generator defined as a maven dependency.
    • org.eclipse.acceleo.anotherGenerator:1.0.0 - Another generator defined as a maven dependency with a restriction on a specific version.
    • C:\Users\MyName\...\myJar.jar - The absolute path of a jar file.
  • packagesToRegister - The name of the Java class that should be used to register the package on which the generation is launched.
  • uriHandler - An AcceleoURIHandler used to convert the URI of the dependencies (if you want a different behavior than the usePlatformResourcePath). The default URI handler provided (org.eclipse.acceleo.maven.AcceleoURIHandler), does the same job as the option usePlatformResourcePath.
  • failOnError - Indicates if the compilation should fail if errors are found (true by default).

Maven Tycho build

Launch this with the following command: mvn clean org.eclipse.acceleo:org.eclipse.acceleo.maven:3.5.0-SNAPSHOT:acceleo-compile compile verify

The following build only manages the compilation of an UML generator that is using another UML plugin as a dependency, for the support of features and update site have a look at Eclipse Minerva.

Plugin Management (parent and children pom.xml)

In order to support a complex maven architecture with a parent pom.xml and children pom.xml, you should declare in the parent pom.xml the following code

 <build>
   <pluginManagement>
     <plugins>
       <plugin>
         <groupId>org.eclipse.acceleo</groupId>
        <artifactId>org.eclipse.acceleo.maven</artifactId>
        <version>3.5.0-SNAPSHOT</version>
         <executions>
           <execution>
             <id>acceleo-compile</id>
             <phase>compile</phase>
             <goals>
               <goal>acceleo-compile</goal>
             </goals>
           </execution>
         </executions>
       </plugin>
     </plugins>
   </pluginManagement>
 </build>

And in the children, the Acceleo configuration, like this

 <build>
   <plugins>
     <plugin>
       <groupId>org.eclipse.acceleo</groupId>
       <artifactId>org.eclipse.acceleo.maven</artifactId>
       <version>3.5.0-SNAPSHOT</version>
       <executions>
         <execution>
           <phase>compile</phase>
           <goals>
              <goal>acceleo-compile</goal>
            </goals>
         </execution>
       </executions>
       <configuration>
         <useBinaryResources>false</useBinaryResources>
         <usePlatformResourcePath>true</usePlatformResourcePath>
         <acceleoProject>
           <root>${project.basedir}</root>
           <entries>
             <entry>
               <input>src</input>
               <output>target/classes</output>
             </entry>
           </entries>
         </acceleoProject>
         <packagesToRegister>
           <packageToRegister>org.eclipse.emf.ecore.EcorePackage</packageToRegister>
         </packagesToRegister>
       </configuration>
     </plugin>
   </plugins>
 </build>

The Acceleo compilation will be launch during the compilation phase without having to specify it in the maven command. It will work with a simple "mvn clean verify".

Known Issues

ClassCast Exception: XXXFactory cannot be casted into a XXXFactoryImpl

It happens sometimes with complex dependencies between generators during a same build (if in the same build, you are building the metamodel and the generators), it should work anyway. Building the meta-model separately and resolving it with a Tycho based dependency and the location of the update site of the meta-model seems to fix this issue.

This issue should be fixed in the latest release.
