Java Module Builder got deleted?

Hey Guys,

i want to develop an Intellij IDEA plugin that adds a project wizard for minecraft plugins, because the existing plugin does not support Kotlin. However, i could not find the JavaModuleBuilder class! I am using idealC 2021.1.3 as Plugin SDK. Could it be that it got deleted in this version? What should i use instead? I just need the general java settings such as a Project JDK selector on the first wizard step page.

Thank you!
