状況：

私は2つのプロジェクトを持っています

  • プロジェクトA.:ネイティブMavenプロジェクト「コア」（ドメイン）
  • プロジェクトB.:GWT Mavenプロジェクト「アプリケーション」（GUI）
  • EclipseHeliosとGWT2.4を使用しています

問題：

A.でB.を使用できません。

A.のB.から自分のクラスを使用することは可能ですが、自分のクラスは他のjar（org.javatuples）からクラスをインポートします。

GWTがクライアントコードをコンパイルしているとき、エラーメッセージをスローします。

"[ERROR] <no source info>: public abstract class org.javatuples.Tuple
    extends java.lang.Object
    implements : Iterable<java.lang.Object>, java.io.Serializable, Comparable<org.javatuples.Tuple>

これが完全なスタックトレースです。

質問：

  • それはMavenの依存関係の問題ですか？
  • GWTはクラスタイプタプルをコンパイルできないため、GWTの問題ですか？
  • この問題を解決する方法やアイデアはありますか？

よろしくアルノ

プロジェクト jar を別の GWT プロジェクトで使用したくない場合は、jar をソース コードと共に提供する必要があります。これを pom ビルド セクションに追加します。

<resources>
  <resource>
    <directory>src/main/java</directory>
    <includes>
      <include>**/client/**</include>
      <include>**/*.gwt.xml</include>
    </includes>
  </resource>   
</resources>

「クライアント」のインクルード パターンをプロジェクトのソース パスに合わせて調整し、再構築します。.java クラスが子プロジェクトで使用可能になると、コンパイルされます。

GWT クライアント コードで javatuples を使用または参照することはできません。これは、そのライブラリが javascript コードにコンパイルできない Java 機能を使用しているためです。
