Compile only groovy files

[danielburrell]

Is it possible for groovy-eclipse-compiler to compile just groovy code rather than both java and groovy?

I want the regular java compiler to be invoked for java (src/main/java, src/test/java), and the groovy-eclipse-compiler used exclusively for anything in src/main/groovy or src/test/groovy. I can't find an example of this on the wiki.
<plugin> <artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <compilerId>groovy-eclipse-compiler</compilerId> </configuration> <dependencies> <dependency> <groupId>org.codehaus.groovy</groupId> <artifactId>groovy-eclipse-compiler</artifactId> <version>2.9.1-01</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>2.3.7-01</version> </dependency> </dependencies> </plugin>

Groovy does not compile Java. It delegates this task to javac in a typical command-line or Ant setting and to ecj in an Eclipse or maven setting. If you want total isolation in a maven setting, you should put Java sources in src/main/java and Groovy/Java interdependent sources in src/main/groovy.
