使用Maven和groovy-eclipse编译器编译Groovy

Question

我有问题让我的Groovy脚本编译。当我开发Groovy脚本时，一切正常，我使用了IntelliJ IDEA IDE和groovy命令行实用程序来运行它，其中@Grapes和@Grab注释。现在，我需要使用Maven转移到编译模型。不幸的是，我无法弄清楚什么是错我pom.xml，为什么Groovy的编译器抱怨这样的：

[ERROR] import org.slf4j.LoggerFactory 
[ERROR]^
[ERROR] The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files 
[...] 
[ERROR] import org.slf4j.LoggerFactory 
[ERROR]^
[ERROR] The type java.lang.String cannot be resolved. It is indirectly referenced from required .class files 

这是我目前pom.xml：

Answer 1

是否有一个原因extensions定义真的吗？我有一个使用groovy-eclipse编译器的项目，我按照groovy-eclipse-compiler plugin page上显示的方向。请注意，那里没有<extensions>标志。

这里是插件配置，对我（使用Groovy 2.2.1）工作原理：

<plugin> 
    <artifactId>maven-compiler-plugin</artifactId> 
    <!-- 2.8.0-01 and later require maven-compiler-plugin 3.1 or higher --> 
    <version>3.1</version> 
    <configuration> 
    <compilerId>groovy-eclipse-compiler</compilerId> 
    <!-- set verbose to be true if you want lots of uninteresting messages --> 
    <!-- <verbose>true</verbose> --> 
    </configuration> 
    <dependencies> 
    <dependency> 
     <groupId>org.codehaus.groovy</groupId> 
     <artifactId>groovy-eclipse-compiler</artifactId> 
     <version>2.8.0-01</version> 
    </dependency> 
    <!-- for 2.8.0-01 and later you must have an explicit dependency on groovy-eclipse-batch --> 
    <dependency> 
     <groupId>org.codehaus.groovy</groupId> 
     <artifactId>groovy-eclipse-batch</artifactId> 
     <version>2.1.8-01</version> 
    </dependency> 
    </dependencies> 
</plugin>
