GWTプロジェクト

Question

にMavenの依存関係を追加し、私は私のGWTプロジェクトを開始し、その後、誰かがそれはMavenを使用するために良いことだ私に言ったので、私は試してみることにしたと私はそれは非常に単純なポンポンファイル生成 私のプロジェクトにMavenの依存関係を追加しました：

を

    <version>0.0.1-SNAPSHOT</version> 
    <packaging>war</packaging> 
</project> 

私はGWTの目標を実行しようとした：GWTをコンパイル：実行、私はそれを初めて実行ダウンロードしたjarファイルの多くと詰まっていること、私はそれをもう一度実行すると、それはこの私をgaves：この場合

助けになる、私は日食の下で働いている 缶誰かが私が間違っていたことを教えて、それをどうやって解決できるの？ありがとうございます。

Answer 1

プロジェクトを作成していくつかの依存関係を追加するだけでは不十分です。まず、適切な構成、適切なプロジェクト構造のcodehausプラグイン、web.xmlとgwt記述子モジュールを使用して、適切な依存関係を追加する必要があります。

mavenでgwtを起動する最も簡単な方法は、archetypeから完全なプロジェクトを生成することです。 http://mojo.codehaus.org/gwt-maven-plugin/user-guide/archetype.htmlをご覧ください。

ちょうどあなたのコンソールを入力GWTプロジェクトを生成するには：

mvn archetype:generate \ 
    -DarchetypeRepository=repo1.maven.org \ 
    -DarchetypeGroupId=demo5 \ 
    -DarchetypeArtifactId=demo5 \ 
    -DarchetypeVersion=2.4.0 

次はあなたのIDEに生成されたプロジェクトをインポートする必要があり、私は次のコマンドを使用してホスト・モードを起動する前に、あなたはそれをコンパイルすることをお勧めします：

mvn gwt:run 

Answer 2

あなたはこのように、GWT SDKが付属しているwebAppCreatorユーティリティで-mavenタグを使用することができます。

webAppCreator -maven -out MyGwtProject com.mycompany.myproject.MyGwtProject
