When I follow the procedure in the readme.txt for the order_dsl_groovy maven project, ti builds successfully, but I get the following message:

$ mvn exec:java -Dexec.mainClass="ch3.order.GroovyScriptEngine"
[INFO] Scanning for projects...
[WARNING] Some problems were encountered while building the effective model for ch3:order:jar:1.0
[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing. @ line 51, column 21
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.

This issue might be related to my inability to import this Maven project into Eclipse. That process worked fine on the other example in Chapter 3, but failed for this one.
If I ignore the errors and import anyway, I get error messages like:
ClientOrder cannot be resolved to a type.
