Compile errors because package name conflicts in SDK jars about sbt-idea-plugin

[rikvdkleij]

I have tried to get it working by excluding jars like in IntelliJ-Scala project but without success.

ideaMainJars := ideaMainJars.value.filterNot(file => excludeJarsFromPlatformDependencies(file.data)),

val excludeJarsFromPlatformDependencies: File => Boolean = { file =>
  (file.getName.contains("openapi") || file.getName.contains("javac2") || file.getName.contains("java-api"))   // version conflict with bsp4j in ultimate platformt

The reason behind this issue is not package name conflict(multiple jars may share the same package safely)

This error occurs because classes you're using in StackCommandLine.scala are part of Java plugin implementation, which has been extracted into a separate entity in IDEA 192.X

The solution would be to add Java plugin as an internal plugin dependency in build:

ideaInternalPlugins += "java"

Also don't forget to add dependency in plugin.xml:

<depends>com.intellij.modules.java</depends>
