なんとなく興味のあるScalaをEclipseとMaven2で使ってみたいなぁと
朝から試行錯誤してみた
とりあえず、ソースコードは書けるようになった
pom.xmlはこんな感じ。長いけどとりあえずコピペすれば良いという状態にしてみた
Scalaと無関係なのもあるけど、それはそれって事で。

mvn eclipse:eclipse
でプロジェクトを生成する
生成終了直後の.projectはこんな感じになってる

</projectDescription>この状態にして、eclipseに取り込めばscalaもjavaも書ける
っていうか、書けることしかまだ確認してないけど忘れそうなのでメモ（笑）
3行消すのを無くさないと気軽にeclipse:eclipseって出来ないんだよね〜どうしよ・・・
つか、ちゃんと動作するのかなぁ〜
