java - maven-ear-plugin contextRoot 被忽略

Question

我一直在使用 maven-ear-plugin 创建 ear bundle 并使用自定义 contextRoot 生成 application.xml(一切正常)。现在我想创建 2 个耳包并将它们部署在不同的上下文路径下，所以我定义了具有 2 个执行的插件。但出于某种原因，maven-ear-plugin 忽略了 contextRoot 属性，并且在生成的 application.xml 中，它在双耳中使用 artifactId 而不是 contextRoot(因此它们具有相同的上下文根“app-ui”)。这是我的 maven-ear-plugin 定义:

<plugin>
    <artifactId>maven-ear-plugin</artifactId>
    <version>2.10</version>
    <executions>
        <execution>
            <id>app1</id>
            <phase>package</phase>
            <goals>
                <goal>ear</goal>
            </goals>
            <configuration>
                <finalName>app1</finalName>
                <modules>
                    <webModule>
                        <groupId>com.x.y</groupId>
                        <artifactId>app-ui</artifactId>
                        <contextRoot>/app1-ui</contextRoot>
                    </webModule>
                </modules>
            </configuration>
        </execution>
        <execution>
            <id>app2</id>
            <phase>package</phase>
            <goals>
                <goal>ear</goal>
            </goals>
            <configuration>
                <finalName>app2</finalName>
                <modules>
                    <webModule>
                        <groupId>com.x.y</groupId>
                        <artifactId>app-ui</artifactId>
                        <contextRoot>/app2-ui</contextRoot>
                    </webModule>
                </modules>
            </configuration>
        </execution>

有什么建议吗？

问题是您只生成一次application.xml，而您需要两个application.xml。为此，您还需要将 generate-application-xml 目标的两次执行绑定(bind)到 Maven 生命周期的 generate-resources 阶段，以生成 application.xml 文件两次(最好在两个不同的文件夹中 ^^)，具有两种不同的配置，如下所示:

<!-- first execution for the first application.xml in folder target/app1/META-INF -->
<execution>
    <id>appxml-app1</id>
    <phase>generate-resources</phase>
    <goals>
        <goal>generate-application-xml</goal>
    </goals>
    <configuration>
        <generatedDescriptorLocation>target/app1/META-INF</generatedDescriptorLocation>
        <modules>
            <webModule>
                <groupId>com.x.y</groupId>
                <artifactId>app-ui</artifactId>
                <contextRoot>/app1-ui</contextRoot>
            </webModule>
        </modules>
    </configuration>
</execution>
<!-- first execution for the generation of the ear with the application.xml in folder target/app1 -->
<execution>
    <id>app1</id>
    <phase>package</phase>
    <goals>
        <goal>ear</goal>
    </goals>
    <configuration>
        <workDirectory>target/app1</workDirectory>
        <finalName>app1</finalName>
        <modules>
            <webModule>
                <groupId>com.x.y</groupId>
                <artifactId>app-ui</artifactId>
            </webModule>
        </modules>
    </configuration>
</execution>

<!-- second execution for the second application.xml in folder target/app2/META-INF -->
<execution>
    <id>appxml-app2</id>
    <phase>generate-resources</phase>
    <goals>
        <goal>generate-application-xml</goal>
    </goals>
    <configuration>
        <generatedDescriptorLocation>target/app2/META-INF</generatedDescriptorLocation>
        <modules>
            <webModule>
                <groupId>com.x.y</groupId>
                <artifactId>app-ui</artifactId>
                <contextRoot>/app2-ui</contextRoot>
            </webModule>
        </modules>
    </configuration>
</execution>
<!-- second execution for the generation of the ear with the application.xml in folder target/app2 -->
<execution>
    <id>app2</id>
    <phase>package</phase>
    <goals>
        <goal>ear</goal>
    </goals>
    <configuration>
        <workDirectory>target/app2</workDirectory>
        <finalName>app2</finalName>
        <modules>
            <webModule>
                <groupId>com.x.y</groupId>
                <artifactId>app-ui</artifactId>
            </webModule>
        </modules>
    </configuration>
</execution>

为了改善这一点，您可以使用变量来确保与 app1 等相关的两次执行的文件夹相同，这只是一个草稿 ;)
