Mac (OS-X Mountain Lion) で問題なくコンパイルできる Java プロジェクトがあります。Ubuntu マシンで同じプロジェクトをコンパイルしようとすると失敗します。
基本的に、クラスが見つからないと不平を言っています。ただし、クラスは Maven クラスパスに存在します。スイッチで実行mvnした後、それを確認しました。-X
(see 612 [DEBUG] /home/c/.m2/repository/org/apache/camel/camel-twitter/2.11.0/camel-twitter-2.11.0.jar ) below.
$HOME/.m2 リポジトリを削除して、すべてを再度ダウンロードするようにしました。しかし、それでも失敗します。
ここで何が欠けているのか分かりますか?
これがUbuntuの私の環境です。
