# multiplatform

Hi everyone,
I’m trying to setup a kotlin multi platform project to generate java and js code from some kotlin classes. In general everything is working with one little problem remaining.
in the gradle root folder a file called build exists, that file cannot be renamed or removed.
it seems like that this file clashes with the generation of js code from the kotlin code. when the multi platform plugin runs an error occurs saying that build is not a directory but a file.

when the file gets temporarily deleted the build works fine an produces the js code
I wonder whether it is possible to somehow tell he multi platform plugin, to use a different folder for the build. the build.gradle
file of the root directory already contains an entry defining that the default build directory is different to build , but somehow that information is not used when the js code gets generated.

the error message

* What went wrong:
A problem was found with the configuration of task ':ys-kcart:jsPackageJson' (type 'KotlinPackageJsonTask').
  - In plugin 'org.jetbrains.kotlin.gradle.scripting.internal.ScriptingKotlinGradleSubplugin' type 'org.jetbrains.kotlin.gradle.targets.js.npm.tasks.KotlinPackageJsonTask' property 'packageJson' is not writable because '/Users/fbernstein/repos/ysura_crm_gradle/build/js/packages/ys-kcart/package.json' ancestor '/Users/fbernstein/repos/ysura_crm_gradle/build' is not a directory.
    
    Reason: Cannot create parent directories that are existing as file.
    
    Possible solution: Configure 'packageJson' to point to the correct location.
