object import from a different package in Scala in Maven project-CodePudding

I need to import an object named JavaCCParser into another object which is in a different package named frontend. But it can not find. I think I write the correct path.

object in a package

import in another package

I add a dependency in pom.xml in frontend package and then solved it. add denpendency

CodePudding user response：

Those don't look like they are in the same module (folder with a blue box, contains its own src root).

To use packages from another module would require you to import the module as a dependency in the other module in the build.sbt.

Something like (for a project-wide build.sbt):

lazy val root = project
    .in(file("."))
    .aggregate( neoForJAstFactory, frontend, ... )
    ... // Other config stuff

lazy val neoForJAstFactory = project
    .in(file("neo4j-ast-factory"))
    ... // Other config stuff

lazy val frontend = project
    .in(file("frontend"))
    .dependsOn(neoForJAstFactory)
    ... // Other config stuff

Once you add the module as a dependency to the module you wish to use it in, the package should be available for import (it should be in-scope).

Here is the sbt doc: Multi-Project
