如何在IntelliJ IDEA中默认导出SBT项目的Compile依赖？

Absolutely! You can fix this frustrating reset issue by configuring your SBT project (Project A) to automatically mark Compile-scoped dependencies as exported for IntelliJ IDEA. This way, the setting persists even after project rebuilds or reimports. Here's what you need to do:

Step 1: Add SBT IDEA Plugin Configuration #

Open Project A's build.sbt file and add the following configuration to override how IntelliJ IDEA generates the module settings:

// Enable the SBT IDEA plugin to customize module generation
enablePlugins(sbt.plugins.IdeaPlugin)

// Adjust module dependencies to export Compile-scoped ones by default
ideaModule := {
  val originalModule = ideaModule.value
  originalModule.copy(
    dependencies = originalModule.dependencies.map { dep =>
      // Mark dependencies in Compile scope as exported; adjust logic if needed for other scopes
      dep.copy(exported = dep.scope.exists(_.name == "Compile"))
    }
  )
}

How This Works: #

• The IdeaPlugin lets us tweak the module metadata that SBT generates for IntelliJ IDEA.
• We modify each dependency in the module: if the dependency is in the Compile scope, we set exported = true. This tells IDEA to make those dependencies available to any project that depends on Project A (like Project B).

Step 2: Apply the Configuration #

• If you're using IDEA's Auto-import for SBT projects, the changes will take effect automatically after saving build.sbt.
• If not, run the sbt idea command in Project A's root directory, then reimport the project into IDEA.

Verification #

After applying the configuration:

1. Go to Project B's module settings in IDEA.
2. Check the dependency on Project A—you'll see the Compile-scoped dependencies from Project A are now marked as exported by default.
3. Rebuild the project; the export setting won't reset anymore.

This approach ensures that the export behavior is defined in your SBT configuration (source-controlled, consistent across environments) instead of relying on IDEA's manual GUI settings that get overwritten.
