maven - EAR の Grails Maven パッケージング

Question

Grails 2.2.x より前は、Maven を使用して grails プロジェクトを作成し、それらを Maven Ear プロジェクトに含めて、すべてが正常に機能していました。Grails 2.2.x の新しい pom.xml は、パッケージタイプを「grails-app」に変更したため、いくつかの新しい問題が発生しています。古いパッケージタイプは「war」で、それで問題なく動作しました。

誰かが同じ問題に遭遇しましたか? 回避策はありますか?

これが私のプロジェクトの構造です。

これは、プロジェクトをビルドしようとした結果です

これを機能させるには、grails アプリケーションを war アーティファクトとして再公開します。Grails アプリケーション pom でこれを行うには、以下を追加します。次に、EAR pom で新しい war アーティファクトを参照します。

<project>
    <modelVersion>4.0.0</modelVersion>
    <artifactId>testGrailsApp</artifactId>
    <packaging>grails-app</packaging>

    <parent>
        <artifactId>testProject</artifactId>
        <groupId>test</groupId>
        <version>0.1-SNAPSHOT</version>
    </parent>

    <properties>
        <grails.version>2.2.1</grails.version>
    </properties>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-install-plugin</artifactId>
                <executions>
                    <execution>
                        <id>create-war-pom</id>
                        <phase>install</phase>
                        <goals>
                            <goal>install-file</goal>
                        </goals>
                        <configuration>
                            <artifactId>${project.parent.artifactId}War</artifactId>
                            <groupId>${groupId}</groupId>
                            <version>${version}</version>
                            <file>${build.directory}/${artifactId}-${version}.war</file>
                            <generatePom>true</generatePom>

            </plugin>
        </plugins>
    </build>

2 つの簡単な変更だけが必要だと思います。

TestGrailsApp pom.xml 親の pom から継承した後、アプリのアーティファクト情報を追加します

<parent> 
   <groupId>test</groupId> 
   <artifactId>testProject</artifactId> 
   <version>0.1-SNAPSHOT</version> 
</parent>

<groupId>test</groupId>
<artifactId>testGrailsApp</artifactId>
<packaging>grails-app</packaging>
<version>0.1</version>
<name>testGrailsApp</name>
<description>testGrailsApp</description>

<properties>
   <grails.version>2.2.1</grails.version>
</properties>

TestEar pom.xml を次のように編集します (タイプを grails-app ではなく war として追加します)。

<dependencies> 
    <dependency> 
        <groupId>test</groupId> 
        <artifactId>testGrailsApp</artifactId> 
        <version>0.1-SNAPSHOT</version>
        <type>war</type>            
    </dependency> 
</dependencies>

完了です。

注: アプリの pom.xml を作成するために「grails create-pom test」を実行しました

理由: TestProject(親) -- TestGrailsApp (子) -- TestEar (子)

Grails Maven プラグインは、暗黙的にライフサイクルで war をビルドします。war ファイルがビルドされたら、ear pom に war を取得し、それを使用して ear にパッケージ化するように通知する必要があります。残りは Maven-ear-plugin が行います。
