Hello everybody,

I wanted some help on multi-platform project, on build.gradle.kts jvm target is set to 1.8

but when i run test errors keeps popping out:
Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6.

any ideas why im getting this?

[Dragos Rachieru]

android?

[Victor Harlan Lacson]

no just jvm

[Dragos Rachieru]

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

[Dragos Rachieru]

what jdk do you use?
if you use intellij you can press ctrl+alt+shift+s and set your level to 8 from there

I have this on gradle kts

kotlin {
    jvm {
        val main by compilations.getting {
            kotlinOptions {
                jvmTarget = "1.8"
                noReflect = false
            }
        }
    }
    ....
}

sorry, i don't know how to use gradle kts yet

i tried that also setting on intellij the jvm-test to 1.8, but keeps returning to 1.6

thanks i will try to look at it

[Victor Harlan Lacson]

this setting never change, test is always set to 1.6, even i set it to 1.8, after running test same problem

[Victor Harlan Lacson]

After tinkering, and trial and error I found the solution. It seems setting on the test is a separate  on the main

kotlin {
    jvm {
        val main by compilations.getting {
            kotlinOptions {
                jvmTarget = "1.8"
                noReflect = false
            }
        }
        // add this code below
        val test by compilations.getting {
            kotlinOptions {
                jvmTarget = "1.8"
                noReflect = false
            }
        }
    }
}

[Joost Klitsie]

there is a way to set it once

[Joost Klitsie]

checking...

[Joost Klitsie]

kotlin {
    jvm() {
        compilations.all {
            compileKotlinTask.kotlinOptions {
                jvmTarget = "1.8"
            }
        }
    }

I did this with android() instead of jvm() but I think it should still work

[Victor Harlan Lacson]

Right, i tried what you said and it works. Thanks
