Question

我的Maven项目已经增长，所以我决定尝试制作一个Maven多模块项目。

我认为它似乎工作得很好，除了Eclipselink元模型类生成。

这是运行mvn clean generate-sources的输出，这是不期望的：

[INFO] javac option: -proc:only

                                                                -Aeclipselink.canonicalmodel.subpackage=metamodel

                                                                -Aeclipselink.canonicalmodel.subpackage=metamodel

                                                                -Aeclipselink.canonicalmodel.subpackage=metamodel] was not found. NO GENERATION will occur!! Please ensure a persistence xml file is available either from the CLASS_OUTPUT directory [META-INF/persistence.xml] or using the eclipselink.persistencexml property to specify its location.

这部分的pom.xml是：

<!-- Generate JPA Criteria Meta Model classes -->
<plugin>
    <groupId>org.bsc.maven</groupId>
    <artifactId>maven-processor-plugin</artifactId>
    <version>2.0.6</version>
    <executions>
        <execution>
            <id>process</id>
            <goals>
                <goal>process</goal>
            </goals>
            <phase>generate-sources</phase>
            <configuration>
                <outputDirectory>${basedir}/target/generated-sources</outputDirectory>
                <compilerArguments>-Aeclipselink.persistencexml=${basedir}/src/main/resources/META-INF/persistence.xml
                    -Aeclipselink.persistenceunits=carcmsPU
                    -Aeclipselink.canonicalmodel.subpackage=metamodel</compilerArguments>
                <processors>
                    <processor>org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor</processor>
                </processors>
            </configuration>
        </execution>
    </executions>
</plugin>

我无法理解为什么这不起作用，它与我单模块项目中的相同。 Maven或Eclipselink似乎在多模块项目中不起作用，或者我在这里错过了什么？
