Question

i tried out the new gradle 6 7 i run gradlew init and create a kotlin multi module project beside that the compile fails of the inital creation i have another question init creates a buildSrc with kotlin kotlin common conventions gradle kts library convention and application convention the plugin dependencies in these files don t contain a version so the plugin block for now looks like this this plugins kotlin jvm jacoco `maven publish` everything works so far the only thing is it uses an old kotlin version how can i force it to 1 4 10 for everything buildsrc and sub modules as soon as i put a version somewhere in my root build gradle kts as an example i get the error message Plugin request for plugin already on the classpath must not include a version any ideas

if i try to set the plugin version in my build gradle kts in buildSrc i get the message The `embedded kotlin` and `kotlin dsl` plugins rely on features of Kotlin `1 3 72` that might work differently than in the requested version `1 4 10`

Is the repo public

Javier · Answer

That warning is normal btw

bitkid · Answer

no can t make it public but it s basically the default which the gradle init spits out

bitkid · Answer

it uses by default kotlin 1 3 72 but i wan t it to use 1 4 10

bitkid · Answer

for everything

Javier · Answer

but 1 3 72 is used inside buildSrc and build gradle kts files for normal projects it is being used the version you defined

Javier · Answer

Javier · Answer

I am ignoring them because we can t upgrade kotlin dsl version

Javier · Answer

I think 6 8 will have Kotlin 1 4 or 1 4 10 but it will not be 1 4 20 probably and 1 4 20 will be available more or less so I don t know if there is an strategy to solve this problem
