# scripting

[serebit]

I'm trying to convert my JSR-223 usages into the new experimental scripting API, but every script I attempt to compile gives me two errors:
- One instance of No class roots are found in the JDK path: /usr/lib64/openjdk-8/jre
- Several instances of Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option

How can I address these?

First seems you're not using proper JDK, but a JRE instead. Second can be fixed with compiler configuration. We need more information about your build environment though to give you better suggestions.

[serebit]

I'm building on Linux, with the JDK at /usr/lib64/openjdk-8. I do have a proper JDK, but the scripting compiler seems to only want to use the JRE.

[serebit]

If I manually set the javaHome property to /usr/lib64/openjdk-8, that error goes away, but the inlining errors persist.

[serebit]

It doesn’t seem to matter what arguments I pass to the scripting compiler, nor what I have IntelliJ or Gradle set to target (1.8 or 1.6). The errors remain.

[Czar]

So let's concentrate on the inlining error then. Can you show compiler configuration and invocation? Specifically, how do you configure ScriptCompilationConfiguration?

[serebit]

Identically to the basic scripting example in the Kotlin repo, with a compilationConfiguration added to the base KotlinScript class to set the javaHome property.

@Czar i have the same issue.. the script configuration currently ignores the passed compiler arguments

I'm switching to Nikky's problem since there I can at least see the code 🙂 @serebit you can check it out when we fix it 🙂
@Nikky am I right in assuming you're talking about your MinimalScriptExample repo?

[Czar]

I've found two issues there:
MinimalScriptingExample\src\main\kotlin\example\script\ScriptEnvironmentConfiguration.kt:19 you have a spelling mistake: -jvm-targe should be -jvm-target
in MinimalScriptingExample\src\main\kotlin\example\script\ScriptEnvironment.kt:8
fileExtension = voodoo.kts should probably be fileExtension = kts or omitted (unless I'm missing something and your script files look like something.voodoo.kts)

[Nikky]

well i designed the minimal scripting example to work..

[Nikky]

i think this error only shows up if you compile your script against some library that was built with the usual -jvm-target 8

[Nikky]

oh i missed that.. i copied it from my own stuff.. i should make this .example.kts

[Czar]

@serebit you can check out Nikky's example and with two changes I've mentioned you can modify and use it for your purposes: https://github.com/NikkyAI/MinimalScriptingExample

@Czar i updated it.. now it fails just like my more complex seperate project

[Nikky]

i am not sure if its the operator function or the fact that it uses inline classes.. but the log is pretty clear in one regard..

[Czar]

@Nikky can you also share your hello.example.kts, because mine works

[Nikky]

it is in the repo

[Nikky]

or should be.. wait..

[Nikky]

now it is

[Nikky]

just clone and execute ./gradlew run should reproduce it

[Czar]

ok, now it works, or rather doesn't 😄

[Nikky]

well i have to go.. i hope you can find a workaround.. this error has been blocking me for months

[Nikky]

also please upvote this: https://youtrack.jetbrains.com/issue/KT-27815 so maybe it surfaces in the issue tracker and gets fixed

[serebit]

Will do. Seems like the main issue I’m having is being unable to set the jvm-target for the scripting compiler, even through the exposed compilerOptions property (so that issue exactly). Hopefully it gets fixed soon.

[Czar]

I've found the probable culprit and will try to contribute a fix next week

Bless 🙏🏿
