2 つの特定の sbt プラグインがビルド定義でプロジェクトに一緒に追加されると、sbt の起動時に次のエラーが発生します。これらの sbt プラグインの 1 つはscalikejdbcで、もう 1 つは自分のです。明らかに、プロジェクトのビルド定義にそれらを相互に含めると、sbt の起動時に次のエラーが発生します。
scala.reflect.internal.Types$TypeError: package macros contains object
and package with same name: blackbox
明らかに、各プラグインが異なるバージョンのscala.reflect.macrosを持ち込んでいるように見えるため、このエラーが発生します。私は sbt プラグインの jar の中を突くことができますscala/reflect/macros/blackbox.class。
$ jar -tvf scalikejdbc-core_2.10/jars/scalikejdbc-core_2.10-2.4.2.jar | grep black
0 Sat Jun 11 15:51:10 IDT 2016 scala/reflect/macros/blackbox/
405 Sat Jun 11 15:51:04 IDT 2016 scala/reflect/macros/blackbox/package$.class
419 Sat Jun 11 15:51:04 IDT 2016 scala/reflect/macros/blackbox/package.class
― しかし、この初期の起動段階で sbt によって何がロードされるかを明確に結論付けるのは困難です。これは、このパッケージのどのバージョンがここに関係しており、どの依存関係がそれらをもたらしているかを把握するためです。
この調査の進め方についてご提案いただきありがとうございます。
完全を期すために、以下に sbt によって提供された完全なエラーのみを含めますが、情報が追加されるとは思えないので、無視してかまいません。
