Joerg Schaible commented on MCOMPILER-165:
------------------------------------------
For M2 this does not matter, the plugin is loaded once and once only.
> Child modules don't seem to be able to use a different compilerId to their
> parent modules when built from the parent POM.

> Key: MCOMPILER-165
> URL: https://jira.codehaus.org/browse/MCOMPILER-165
> Project: Maven 2.x Compiler Plugin
> Issue Type: Bug
> Affects Versions: 2.3.2
> Reporter: Edd grant
> Attachments: multiple-pom-mixed-java-groovy-project-test.zip
>
>
> I have a mixed Java/ Groovy project which is split over several Maven
> modules, all of which have a common parent module. In the parent POM I
> specify some basic common options for the {{maven-compiler-plugin}} (see
> example 1 below). The idea being that in my child modules I can either simple
> use this configuration by specifying the plugin with no further configuration
> (example 2), or I can override this configuration if I have specific
> requirements (for example switching the {{compilerId}}) (example 3).
> Example 1 - Parent POM:
> {code}
> <pluginManagement>
> <plugins>
> <plugin>
> <artifactId>maven-compiler-plugin</artifactId>
> <version>2.3.2</version>
> <configuration>
> <source>1.6</source>
> <target>1.6</target>
> </configuration>
> </plugin>
> </plugins>
> </pluginManagement>
> {code}
> Example 2 - Child POM that inherits the parent POM's plugin configuration:
> {code}
> <plugin>
> <artifactId>maven-compiler-plugin</artifactId>
> </plugin>
> {code}
> Example 3 - Child POM that specifies a different compilation configuration
> (uses the {{groovy-eclipse-compiler}}) to the parent POM's configuration:
> {code}
> <plugin>
> <artifactId>maven-compiler-plugin</artifactId>
> <configuration>
> <compilerId>groovy-eclipse-compiler</compilerId>
> <verbose>true</verbose>
> <source>1.6</source>
> <target>1.6</target>
> </configuration>
> <dependencies>
> <dependency>
> <groupId>org.codehaus.groovy</groupId>
> <artifactId>groovy-eclipse-compiler</artifactId>
> <version>2.6.0-01</version>
> </dependency>
> </dependencies>
> </plugin>
> {code}
> Using this configuration everything works fine if I build ({{mvn clean
> install}}) each POM individually, however when I build the project from the
> parent POM compilation of the module with the switched {{compilerId}} fails
> and I get the following error:
> {code}
> [ERROR] BUILD ERROR
