Java 9 with Springブート2はGroovyクラスを検出できません

Question

Java 9でSpringBoot 2.0.0を実行しようとしています。メインクラスを実行し、Intellij RunAsオプションを使用してすべてのサービスにアクセスできますが、mvn clean install、 Javaクラスの場合のみ正常に動作しますが、JavaクラスのGroovyクラスへの参照がある場合、エラーが発生します。

MyServiceはGroovyクラスであり、次のエラーはMyController.javaのimport文であり、MyServiceが参照されるたびに同じエラーが生成されます。

**/Users/services9/src/main/java/com/my/controller/MyController.java:[9,24] cannot find symbol 
[ERROR] symbol: class MyService 
[ERROR] location: package com.my.service**

おそらく、さらに以下の構成でmaven-compiler-pluginを設定するには、見逃している：Groovy-Eclipse-Maven-pluginドキュメントに記載されているように

<build> 
... 
<plugins> 
    <plugin> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <version>3.6.1</version><!-- 3.1 is the minimum --> 
    <configuration> 
     <compilerId>groovy-eclipse-compiler</compilerId> 
     <compilerArgument>indy</compilerArgument><!-- optional; supported by batch 2.4.12-04+ --> 
    </configuration> 
    <dependencies> 
     <dependency> 
     <groupId>org.codehaus.groovy</groupId> 
     <artifactId>groovy-eclipse-compiler</artifactId> 
     <version>2.9.2-03</version> <!--latest --> 
     </dependency> 
     <dependency> 
     <groupId>org.codehaus.groovy</groupId> 
     <artifactId>groovy-eclipse-batch</artifactId> 
     <version>2.4.12-04</version><!--latest--> 
     </dependency> 
    </dependencies> 
    </plugin> 
...
