when trying to extract out my annotations off a class i get this (using 2.0.0-1.0.21):

ERROR CLASS: Symbol not found for Entity

I have this code:

val annotations = klass.annotations.toList()

and in that list, the count is correct but if I try to extract out info I get null:

it.annotationType.resolve().declaration.qualifiedName?.asString()

that declaration returns a KSErrorTypeClassDeclaration. It seems like ksp can't find the classdef for that type but it's definitely on my test's classpath. any idea what's going wrong?

[evanchooly]

klass is a KSClassDeclaration

Did you use ksp.useKSP2=true? If not, is this a MPP project?

[evanchooly]

i'm running ksp programmatically atm not from, say, gradle.

[evanchooly]

basically mimicking the KspJvmMain.kt approach

[Ting-Yuan Huang]

How is the classpath setup? KSPConfig.libraries?

If the annotation class is defined in yet-to-be-compiled Java sources, a common pitfall is directories not matching package name. It also has to be within the same compilation unit, instead of libraries (if not compiled yet).

[evanchooly]

well, the annotation is defined in src/main but i'm running my processor from src/test so let me try and clean that up a little bit. this should all (mostly) be in src/main anyway

[evanchooly]

ok. so that didn't help. 😕

[evanchooly]

well, now, those annotations are actually defined in another maven module (and installed to the local repo) and that module is included on the classpath. so I'm not sure what else I need to tell ksp in order to find them.

[evanchooly]

would the (JPMS) module name matter? because my stuff is not in a module but the configuration requires a module name so I gave it ""

[Ting-Yuan Huang]

Did you put it in KSPConfig.libraries ?

[evanchooly]

where would I put that?

[evanchooly]

oh, i see. is that exposed in the builder?

yep: https://github.com/google/ksp/blob/main/common-deps/src/main/kotlin/com/google/devtools/ksp/KSPConfig.kt#L40

[evanchooly]

i owe you a beverage of your choice! that was it.

[evanchooly]

i went looking for that yesterday and completely overlooked it. Thanks.

Glad to help!
