忽略maven-ear-plugin contextRoot

Question

我一直在使用maven- ear插件来创建ear包，并使用自定义的application.xml生成contextRoot (一切都很好)。现在我想要创建两个ear包，并在不同的上下文路径下部署它们，所以我用2次执行定义了插件。但出于某种原因，maven-ear插件忽略了contextRoot属性，而在生成的application.xml中，它在两耳中使用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，而需要两个application.xml。为此，还需要在maven生命周期的generate-application-xml阶段上执行两次绑定的generate-resources目标，以便用以下两种不同的配置生成application.xml文件两次(最好是在两个不同的文件夹中^)：

<!-- 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>

为了改进这一点，您可以使用变量来确保与app1有关的两次执行的文件夹是相同的，这只是一个草案;)
