I like how I am able to jump to a method when using JUnit's MethodSource, is there a way to define the same behaviour for a custom annotation, also requiring a method name?

[ephemient]

it's built into the JUnit plugin: https://github.com/JetBrains/intellij-community/blob/master/plugins/junit/src/com/intellij/execution/junit/references/JUnitReferenceContributor.kt

thanks for the pointer

Dont think the issue is necessary, this is built into IDE as language injection. Inject language on your annotation string parameter and use method reference

[robstoll]

can you point me to something how

Inject language on your annotation string parameter and use method reference

can be done?

[ephemient]

I assume they mean something like

annotation class MySource(
    @Language("java")
    val method: String,
)

@MySource("com.example.Something::somehow")

[ephemient]

but in any case, the IDE integration isn't a JUnit issue

[efemoney]

internal annotation class InternalMediaApi(
  @Language("jvm-method-name") val string: String = ""
)

[ephemient]

if you want it to work a specific different way, you can write your own intellij plugin

[robstoll]

nice, glad I asked, the @Language annotation solved my issue nicely 🙂

[robstoll]

@efemoney do you know by chance if there is a workaround so that the @Language annotation works across dependencies? I.e. I would like to use my custom annotation in another projects where the custom annotation is defined as dependency

[efemoney]

The Language annotation is part of intellij annotations artifact (just ask AI for the GAV coordinates and use the latest version), you can add it as a dependency just like your annotation module, or make your annotation module depend on it so that its automatic for consumers

[robstoll]

that's not the problem, the problem is that the @Language I define in project A is completely ignored by intellij in project B

[efemoney]

Interesting, I havent faced that issue before

[robstoll]

that's a pity, you have been my last hope 😆

[robstoll]

same behaviour if you use it in a kotlin/java mixed project, works in kotlin but not in java. As a workaround I create the same annotation in java as well (different package of course). Quite cumbersome
