Maven复制资源执行两次 for profile once default

Question

我有一个 Maven 项目，我在其中定义了一个基于 profile 的构建，包括自定义 maven-resource-plugin 配置。

...
<profiles>
    <profile>
        <id>docker</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-resources-plugin</artifactId>
                    <version>3.1.0</version>
                    <executions>
                        <execution>
                            <id>resources</id>
                            <phase>generate-resources</phase>
                            <goals>
                                <goal>copy-resources</goal>
                            </goals>
                            <configuration>
                                <outputDirectory>${basedir}/target/classes</outputDirectory>
                                <resources>
                                    <resource>
                                        <directory>${basedir}/src/main/resources</directory>
                                        <filtering>false</filtering>
                                        <excludes>
                                            <exclude>log4j2*.xml</exclude>
                                            <exclude>docker/*</exclude>
                                        </excludes>
                                    </resource>
                                </resources>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>
...

现在当我执行例如mvn compile -P docker我可以看到资源插件被执行了两次。

INFO] --- maven-resources-plugin:3.1.0:copy-resources (resources) @ mma-access-management-auth-server ---

[INFO] Using 'UTF-8' encoding to copy filtered resources.

[INFO] Copying 2 resources

[INFO] --- maven-resources-plugin:3.1.0:resources (default-resources) @ mma-access-management-auth-server ---

[INFO] Using 'UTF-8' encoding to copy filtered resources.

[INFO] Copying 5 resources

这样对吗？我真的必须排除默认构建的所有资源以避免通过默认资源再次复制它们吗？

不要再将插件绑定到生成资源阶段。仅使用配置标签时，可以更改默认执行的配置。

...
<profiles>
    <profile>
        <id>docker</id>
        <build>
            <plugins>
                <plugin>
                    <artifactId>maven-resources-plugin</artifactId>
                    <version>3.1.0</version>
                    <configuration>
                        <resources>
                            <resource>
                                <directory>${basedir}/src/main/resources</directory>
                                <filtering>false</filtering>
                                <excludes>
                                    <exclude>log4j2*.xml</exclude>
                                    <exclude>docker/*</exclude>
                                </excludes>
                            </resource>
                        </resources>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>
</profiles>
