When scanning the whole classpath a MemberNotFoundException occurs

[anjunar]

What can I do to solve that Exception?

I don't want to add these Dependencies.

For example jakarta.el is needed for jakarta.validation.

But I don't want to add jakarta.el

So now I am scanning jakarta.validation and there exists a dependency to jakarta.el and then the MemberNotFoundException occurs

tasty-query requires a valid classpath to function. Depending on what methods you call (notably the ones without a using Context), you may get by without dependencies. But in general you need the dependencies on the classpath for tasty-query to be able to do its job.

[anjunar]

Hmmm... But it is quite often, that not all dependencies are provided.

I only scanned the Classpath with context.findSymbolsByClasspathEntry(entry) and there the exception occurs

Why it can't be implemented?

[sjrd]

It seems a bit surprising to me that findSymbolsByClasspathEntry looks up external members. Except perhaps if they are package members? Could you provide the full error message and stack trace?

[sjrd]

You might want to try out #347 (you can build it locally with sbt publishLocal). Maybe it fixes your issue by construction.

Here is the full stack trace:

It throws an exception because of Hibernate Validator

  .settings(
    name := "tasty-reflections",
    idePackagePrefix := Some("com.anjunar.tasty.reflections"),

Hi, I tried the Snapshot version, but the Exception still occurs...

[sjrd]

It's not merged yet so you'll need to build it locally it you want to try.

[anjunar]

Now I got another Bug. I left out tasty-query from the classpath, then everything is right.

But with tasty-query in the classpath I got this Exception:

@sjrd I have now a own Classloading mechanism.

I only load classes, that are required by a package. So I left out all classes, that are not used.

[sjrd]

I believe all the issues mentioned here have been fixed in recent versions.

On addition, since v1.0.0, classpath entries are an interface that can have alternative implementations in user space.
