Please provide full example for a kotlin project

[ogesaku]

Hey, thanks for the library!

I would like to use jte in a kotlin project, but keep hitting walls. It would be really handy to have a full example of the most basic usage:

• any web server using .kte templates
• jte-kotlin as compileOnly as described in Add kotlin and kte documentation #351
• template hot-reloading for development and precompilation for production
• configured using build.gradle.kts - as this is the standard for modern kotlin projects

My findings so far:

• jte-kotlin as compileOnly doesn't work for development. Fails with gg.jte.TemplateException: Failed to create kotlin generator. To handle .kte files, you need to add gg.jte:jte-kotlin to your project.. Unfortunately I think it must be specified as implementation but then it comes with a whole lot of kotlin compilation dependencies.
• Intellij jte plugin stops working randomly (stops displaying hints), doesn't recognise nested fields and fails for @import with Package directive and imports are forbidden in code fragments

Env:

• Intellij: IntelliJ IDEA 2024.3 (Community Edition) Build #IC-243.21565.193, built on November 13, 2024, Kotlin plugin: K2 mode
• kotlin: 2.0.21, 2.0.20

Hi @ogesaku,

I don't use much Kotlin so can't help with most points here.

But, there is currently a problem with the IntelliJ plugin in K2 mode, with no practical solution yet: casid/jte-intellij#49

You could try if disabling K2 mode in IntelliJ helps, but this isn't a long term solution I'm afraid.

I have basically the same feedback, couldn't get to work the gradle plugin with jooby.
create testapp -g --docker -k --openapi --server netty

and simply trying adding to the build.gradle.kts:

plugins {
    id("java")
    id("gg.jte.gradle") version "3.1.15" // this fails
}

dependencies {
    implementation("gg.jte:jte:3.1.15")
}

jte {
    generate()
}

Crashes with error:
java.lang.NoClassDefFoundError: Could not initialize class org.jetbrains.kotlin.gradle.report.ConfigureReporingKt (...)

My setup:
------------------------------------------------------------
Gradle 8.6

Kotlin:       1.9.20

OS:           Mac OS X 15.1.1 aarch64

Upon upgrading Gradlew versions to 8.7 and up to current 8.12 I get a different error:

* What went wrong:
class org.jetbrains.kotlin.build.report.metrics.GradleBuildTime can not implement org.jetbrains.kotlin.build.report.metrics.BuildTime, because it is not an interface (org.jetbrains.kotlin.build.report.metrics.BuildTime is in unnamed module of loader org.g

Is there a compatibility matrix on what gradle, gradle plugin, kotlin and jte versions are working? I find strange to have a jte-kotlin maven example and not a kotlin-gradle one when the majority of kotin projects use gradle.
I understand that K2 and the Intellij plugin are not working, but I would even settle for no IDE support, not .kte support, etc.. if I was able to get at least the gradle plugin working with .jte files.

Let me know if there is anything I can help.

It seems there are some problems with the jte gradle plugin and the latest version of Kotlin. #412

I think @marcospereira is working on a fix here #411, but I can't tell you when that one will be ready.
