Eric Milles closed GROOVY-11116.
--------------------------------
Resolution: Information Provided
> 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: 2.5.21, 3.0.15, 4.0.9
> Reporter: Björn Kautler
> Priority: Major
>
> 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
