--------------------------------------
Summary: Groovy does not handle missing classes gracefully like
Java does
Key: GROOVY-11116
URL: https://issues.apache.org/jira/browse/GROOVY-11116
Project: Groovy
Issue Type: Bug
Affects Versions: 4.0.9, 3.0.15, 2.5.21
Reporter: Björn Kautler
When executing the snippet
{code}
@Grab('club.minnced:discord-webhooks:0.8.2')
import club.minnced.discord.webhook.WebhookClientBuilder
new WebhookClientBuilder(1, "").setWait(false)
{code}
Groovy fails with a {{ClassNotFoundException}}.
Also using {{@CompileStatic}} does not help it just changes the thrown error a
bit.
When Groovy tries to initialize the members of {{WebhookClientBuilder}}, it
tries to initialize internal method representations for all methods.
Some of the methods use classes in their signature that are optional for that
library.
>From Java this works perfectly fine as long as you don't use any of the
>methods that need those optional dependencies.
But in Groovy, this does not work, as Groovy always tries to read all methods
fully.
It would be nice if Groovy could be made more lenient here and only fail if one
of the methods with missing dependencies is actually tried to be used.
The only work-around I found is using the {{WebhookClientBuilder}} only from a
Java class that is then used from the Groovy code
