I have tried migrating from gradle Intellij plugin (1.x) to newer IntelliJ platform Plugin. But as i am not good with gradle tasks, i hope someone can please look into that and help me point in the right direction.

We should also add gradle properties like sinceBuild and updateBuild i am not really sure about them.

I was also trying to add the new syntax for "runIdeForUiTest" task, but again i am not sure about that.

So yes this pr really needs a review from someone !.

Also can you please give it a "hacktoberfest-accepted" tag, it will help me complete the hacktober-fest challenge

@He1pa @Peefy can you please look into it.

Do you have any documentation about sinceBuild and updateBuild or where did you refer to this migration? Previously we had

pluginSinceBuild = 221
 # pluginUntilBuild = 233.*

in gradle.properties. It means supported build number ranges and IntelliJ Platform versions
We set a minimum version but no maximum version to be compatible with subsequent new versions.
I am not sure if this means the same property
