I am having issues getting my Groovy script to compile. When I was developing the Groovy script everything worked fine, I used IntelliJ IDEA IDE for it and groovy
command line utility to run it, with @Grapes
and @Grab
annotations. Now, I need to move to compiled model using Maven. Unfortunately, I am unable to figure out what is wrong with my pom.xml
, why the Groovy compiler complains like this:
[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
This is my current pom.xml
:

Is there a reason extensions
is defined as true? I have a project that uses the groovy-eclipse-compiler, I followed the directions as shown on the groovy-eclipse-compiler plugin page . Note there is no <extensions>
flag there.
Here is the plugin configuration that works for me (using Groovy 2.2.1):
<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>
