Question

我有一个包含persistence.xml的独立jar。这个jar已作为依赖项添加到具有实体的jar的父pom中。我想启用静态编织。根据{{3}}，我可以将persistenceXMLLocation指定为配置。但是，此位置应该是我的persistence.xml的绝对文件路径还是存储库中的路径。另外，如何在启用编织的情况下构建我的实体jar？执行这个插件的maven命令是什么？

以下是执行插件时出现的错误：

    Failed to execute goal de.empulse.eclipselink:staticweave-maven-plugin:1.0.0:weave (default-cli) on project BRBASE-techl-entities: Execution default-cli of goal de.empulse.eclipselink:staticweave-maven-plugin:1.0.0:weave failed:
[ERROR] Exception Description: An exception was thrown while trying to load persistence unit at url: file:/D:/BRIDGE/BRIDGE-PARTIAL/BRBASE_Branch_selective_fetch/src/core/techl/entities/target/classes/

这里，它在实体项目的类路径中查找persistence.xml文件。

我使用的mvn命令是：

de.empulse.eclipselink:staticweave-maven-plugin:weave

该插件是：

                    </dependency>
                </dependencies>
            </plugin>

使用的EclipseLink版本：2.5.1-RC1

我有什么遗失的吗？

我也像你一样尝试了absolulte路径并且没有用。

我认为外部资源文件不是最好的做法。但您可以使用maven-resources-plugin：2.6：在资源 - 资源阶段将资源复制到＆lt; #maven-module＆gt; / target / classes的资源。

<resources>
    <!-- ... -->
    <resource>
        <directory>D:/BRIDGE/BRIDGE-PARTIAL/DB/persistence-config/src/main/resources</directory>
        <includes>
            <include>META-INF/persistence.xml</include>
        </includes>
    </resource>
</resources>

而staticweave-maven-plugin：1.0.0：weave在process-classes阶段运行。因此，persistence.xml位于此阶段的＆lt; #maven-module＆gt; /target/classes/META-INF/persistence.xml中。

使用相对路径并设置

<persistenceXMLLocation>META-INF/persistence.xml</persistenceXMLLocation>

在staticweave-maven-plugin的配置中。

如何使用Maven在远程persistence.xml中使用eclipseLink启用静态编织？
