Maven shaded plugin replacing persistence.xml

Question

during maven package i have a strange behavior. I have an artifact "A" that depends from "B".

Within "A" i have a folder META-INF that contains a persistence.xml, also in "B" I have a folder that META-INF with a persistence.xml.

This is pom's file of A relative to shade plugin and dependencies

    <dependency>
        <groupId>com.mycopany</groupId>
        <artifactId>B</artifactId>
        <version>1.0.2</version>
       </dependency>
   </dependencies>


        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.4.2</version>
            <configuration>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>META-INF/*.SF</exclude>
                            <exclude>META-INF/*.DSA</exclude>
                            <exclude>META-INF/*.RSA</exclude>
                        </excludes>
                    </filter>
                </filters>
                <shadedArtifactAttached>true</shadedArtifactAttached>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

How can I exclude the persistence.xml file from "B", considering that "B" is also a shaded artifact?

use a second filtre and exclude persistence.xml like this :

                <filter>
                    <artifact>B</artifact>
                    <excludes>
                        <exclude>path/persistence.xml</exclude>  
                    </excludes>
                </filter>

more details is in this question and in the official documentation

Somehow this doesnot work for me. Can you give an example of "path"? – SSharma Jun 09 '20 at 15:18

One solution I found is to Create JPA EntityManager without persistence.xml configuration file. I have used PersistenceUnitInfo.

Here is the original thread : Create JPA EntityManager without persistence.xml configuration file

This will come in handy for PersistenceUnitInfo:https://docs.oracle.com/javaee/7/api/javax/persistence/spi/PersistenceUnitInfo.html – Gokul G.K Dec 01 '21 at 09:47
