I’m migrating a project from Java 8 to Java 11 and when setting the jvmTarget to 11 in the kotlin plugin, my DSL does not work anymore, the project is here: ``` https://github.com/lburgazzoli/camel-kotlin-runner ``` When I change the property kotlin.jvm.target from 1.8 to 11, then the tests fails like none of the methods of my dsl are invoked anymore. Note that the DSL is consumed by a kotlin script ---

You should provide the actual error. Otherwise, it is hard to understand what exactly is broken. ---

I don’t actually have a real error but a failure in a unit test, so I define a kotlin script like: ``` @KotlinScript( fileExtension = "kts", compilationConfiguration = KotlinCompilationConfiguration::class) abstract class IntegrationConfiguration( private val builder : EndpointRouteBuilder) : BuilderSupport(builder.context), Support, EndpointBuilderFactory { fun rest(): RestDefinition { return builder.rest() } fun camel(block: CamelConfiguration.() -> Unit) { CamelConfiguration(context).block() } } ``` then I have a test that validates the `camel` block and by setting the `jvmTarget` to 1.8, all of them succeed but when switching to Java 11 as `jvmTarget`, they start to fail. adding some log or trying to debug them shows that the `camel` method is not invoked at all when `jvmTarget` is set to 11 ---

You still didn’t tell us what breaks. What failure in a unit test? What’s the output? What’s the difference between expected and actual values. etc. ---

The tests defines this script: ``` camel { components { component("seda") { queueSize = 1234 concurrentConsumers = 12 } component("mySeda") { queueSize = 4321 concurrentConsumers = 21 } } } ``` And checks that the components named “seda” and “mySeda” have the right values, but when switching to java 11 as jvmTarget it fails with: ``` [ERROR] KotlinRouteLoaderTest.load routes with components configuration:51 Expecting to have a property or a field named <"queueSize"> with value <1234> but value was: <1000> ``` Note that 1000 is the default value. So there’s no “technical error” like i.e. an incompatible class or method but just a unit test failing so the script engine seems to fails silently to interpret the DSL. ---

That is interesting, and the approach (script configuration) is interesting. But I am not able to reproduce the problem, works with 1.8, 11, and 13. This is on linux with openjdk, did you different version of the jdk? ---

Ok, I’am able to reproduce the problem. Looks to me like the script is not being evaluated at all, but I have no idea why either. ---

I do have other tests in another project and it looks like only the “blocks” like ``` fun camel(block: CamelConfiguration.() -> Unit) ``` Are not evaluated, methods with simple types, such as ``` fun from(uri: String): RouteDefinition ``` Are instead ok ---

Please process ‘eval’ results in KotlinRouteLoader:52 They will point to ```auto 2 = {ScriptDiagnostic@11868} "ERROR Cannot inline bytecode built with JVM target 9 into bytecode that is being built with JVM target 1.8. Please specify proper '-jvm-target' option (script.kts:3:9)" 3 = {ScriptDiagnostic@11869} "ERROR Cannot inline bytecode built with JVM target 9 into bytecode that is being built with JVM target 1.8. Please specify proper '-jvm-target' option (script.kts:7:9)" ``` Script targets should be also increased ---

nevermind, found it: ``` KotlinCompilationConfiguration : ScriptCompilationConfiguration { jvm { compilerOptions.append("-jvm-target") compilerOptions.append("11") } } ```
