How can I include a few classes in a Groovy script?
(This question has nothing to do with REST, but I use REST to put the question in the right context)
Background: I am developing a CLI in groovy to get status information from a service we are running. The status information is exposed as a REST interface.
Depending on the argument I give on the CLI, different paths are called on the REST interface. I have also put the actual REST communication in a class hierarchy to be able to reuse the code and this is where I have the problem. How can I include the class hierarchy in my groovy script in an easy way?
Groovy CLI-script RestCli.groovy
import restcli.RestA
import restcli.RestB
if(args[0] == "A") {
new RestA().restCall()
}
else if(args[0] == "B") {
new RestB().restCall()
}
Super class for the hierarcy restcli/RestSuper.groovy
package restcli
abstract class RestSuper {
protected def restCall(String path) {
println 'Calling: ' +path
}
abstract def restCall()
}
Two classes to implement different calls. restcli/RestA.groovy
package restcli
class RestA extends RestSuper {
def restCall() {
restCall("/rest/AA")
}
}
and restcli/RestB.groovy
package restcli
class RestB extends RestSuper {
def restCall() {
restCall("/rest/BB")
}
}
The result I want to get is simply:
> groovy RestCli.groovy B
Calling: /rest/BB
Any ideas on how to do this?
I would actually like to avoid creating a jar file and then use the -classpath
option, because I'm also using @Grab
to get http-builder and if I use -classpath
then I'm getting problems like this one: java.lang.NoClassDefFoundError: groovyx.net.http.HTTPBuilder
You can put multiple classes in one groovy script (not sure how/if packages work that way) or just create the package structure as a directory structure in the same folder as your main script.
In your example that could look like this:
/
+ RestCli.groovy
+ restcli/
+--+ RestSuper.groovy
+--+ RestA.groovy
+--+ RestB.groovy
You could then call your script like this:
> groovy RestCli.groovy B
