Being a CQ5 developer<\/a>, I have to register components and services almost everyday. Knowing how powerful Groovy is, I wanted to replace all Java code with Groovy. First step towards it was being able to compile Groovy. I got it to work with the help of this blog<\/a>.<\/p>\n

Although I was facing following problem even after this:<\/p>\n

– I was not able to register component as a service or component. Infact none of the SCR annotations seemed to work with Groovy. I had following maven-scr plugin configration.<\/p>\n

[html]<\/p>\n

<plugin>
\n <groupId>org.apache.felix<\/groupId>
\n <artifactId>maven-scr-plugin<\/artifactId>
\n <executions>
\n <execution>
\n <id>generate-scr-descriptor<\/id>
\n <goals>
\n <goal>scr<\/goal>
\n <\/goals>
\n <\/execution>
\n <\/executions>
\n <\/plugin><\/p>\n

[\/html]<\/p>\n

Tried a lot of things for this and this is how I got it work(thanks to suggestions from a group):<\/p>\n

[html]<\/p>\n

<plugin>
\n <groupId>org.apache.felix<\/groupId>
\n <artifactId>maven-scr-plugin<\/artifactId>
\n <configuration>
\n <scanClasses>true<\/scanClasses>
\n <\/configuration>
\n <executions>
\n <execution>
\n <id>generate-scr-descriptor<\/id>
\n <goals>
\n <goal>scr<\/goal>
\n <\/goals>
\n <\/execution>
\n <\/executions>
\n <\/plugin><\/p>\n

[\/html]<\/p>\n

By default maven-scr plugin compiles only Java Classes. To make it aware of Groovy classes also, a configuration “scanClasses” has to be set to true.<\/p>\n

Updated:<\/p>\n

There are 2 more configuration changes that are needed:<\/p>\n

1) I had to change version of maven-scr-plugin from 1.7.4 to 1.17.0<\/p>\n

[java]<\/p>\n

<plugin>
\n<groupId>org.apache.felix<\/groupId>
\n<artifactId>maven-scr-plugin<\/artifactId>
\n<version>1.17.0<\/version>
\n<\/plugin><\/p>\n

[\/java]<\/p>\n

2) Change version of felix scr annotation to 1.9.8<\/p>\n

[java]<\/p>\n

<dependency>
\n<groupId>org.apache.felix<\/groupId>
\n<artifactId>org.apache.felix.scr.annotations<\/artifactId>
\n<version>1.9.8<\/version>
\n<scope>provided<\/scope>
\n<\/dependency><\/p>\n

[\/java]<\/p>\n

Adding this code worked like a charm.<\/p>\n

Hope this helps CQ5 developers who love Groovy(like me. :))…<\/p>\n
