Is it not possible to use kotlin in an `init gradle` script

Question

Is it not possible to use kotlin in an `init gradle` script I m trying to reference a property using `by project` but I get the error message ``` Line 1 val ptSnapshotsReaderPassword String by project ^ Function invocation project expected ```

eskatos · Answer

your script should be named ` init gradle kts` to use the Gradle Kotlin DSL

snowe · Answer

it is

snowe · Answer

wait ` `

snowe · Answer

it s named `init gradle kts`

eskatos · Answer

The important part for it to work from the command line is the ` gradle kts` extension

eskatos · Answer

Naming it ` init gradle kts` will make the IDEs understand that it is an initialization script and provide you with the right set of APIs

eskatos · Answer

See <https docs gradle org current userguide kotlin dsl html sec scripts>

eskatos · Answer

ah I see it s already named ` gradle kts` I got confused because your original message says the file is named `init gradle`

snowe · Answer

oh i think the name is an `init gradle` script or initialization script

snowe · Answer

yes I have it named properly

snowe · Answer

I ve used kotlin gradle scripts many many times before

snowe · Answer

just trying to convert my `init gradle` to `init gradle kts` and am getting the above errors

eskatos · Answer

`project` is not available in an init script an init script is evaluated against the `Gradle` instance the available api is not `Project` See <https docs gradle org current userguide init scripts html>

eskatos · Answer

and <https docs gradle org current dsl org gradle api invocation Gradle html org gradle api invocation Gradle>

snowe · Answer

yes I realize that but `~ gradle gradle properties` is not a project level properties

snowe · Answer

it s a gradle property

snowe · Answer

it references perfectly fine when it s an `init gradle` file but not when I change it to kotlin

snowe · Answer

Oh I see the confusion it s because I m using `by project` I m really asking how to retrieve the properties from `~ gradle gradle properties` within an `init gradle kts` file I don t really care how it s done

eskatos · Answer

Groovy grabs the property value by reflection

eskatos · Answer

You can use `by settings` or `by project` in an init script but you need to do that in a block that provides access to settings project

eskatos · Answer

``` gradle settingsEvaluated val myProperty String by settings println From settings $myProperty gradle rootProject val myProperty String by project println From root project $myProperty ```

snowe · Answer

fantastic

snowe · Answer

that seems to work ```settingsEvaluated val ptSnapshotsReaderPassword String by settings settings pluginManagement repositories if findProperty mavenLocal = null mavenLocal gradlePluginPortal jcenter maven credentials username = pt snapshots reader password = ptSnapshotsReaderPassword resolutionStrategy eachPlugin if requested id namespace == net researchgate useModule net researchgate gradle release 3 0 0 RC3 ```

snowe · Answer

now I need to figure out how to get the `findProperty` block to work

eskatos · Answer

you can simplify `settings pluginManagement ` to just `pluginManagement `

snowe · Answer

yes I wanted to be explicit since this is converting from gradle it looks closest if I use `settings`

eskatos · Answer

ymmv slightly smiling face

snowe · Answer

ha final solution ```settingsEvaluated val ptSnapshotsReaderPassword String by settings val mavenLocal Boolean by settings pluginManagement repositories if mavenLocal = null mavenLocal gradlePluginPortal jcenter maven credentials username = pt snapshots reader password = ptSnapshotsReaderPassword url = uri resolutionStrategy eachPlugin if requested id namespace == net researchgate useModule net researchgate gradle release 3 0 0 RC3 ```
